A big part of the drive for PierMesh is that I think based on Meshtastics ability to run on low power low cost boards that can be managed via a cellphone would make them helpful in disaster situations and particularly what Palestinians are going through right now. I've been trying to reach out to anyone in tech who is Palestinian/helping Palestinians who could spare some time to let me know if the efficacy of using LoRa (long range low power radio networking that can connect over kilometers) is worth trying to get some boards in that are preconfigured and encrypted. I have a lot more details I can provide and if you want to do some preliminary research yourself Meshtastics website is a good place to start:

What PierMesh would provide on top of this in its current state is multilingual support and currently I'm working on end to end encryption but even without that I think this technology could be very useful.

Thank your for your time

[ad_1] As someone who's followed the evolution of Meshtastic devices closely, I've been eager to get my hands on the WisMesh Pocket V2 to see how it compares to its predecessor and other options on the market. Based on the WisMesh Base Board RAK19026, this new iteration promises significant improvements in expandability and functionality. Let's dive into what makes this $99 device worth considering for mesh networking enthusiasts.Unboxing and Initial ImpressionsOpening the WisMesh Pocket V2 package reveals a well-presented collection of components:The WisMesh Pocket V2 device itselfA LoRa antennaA USB Cable4 sets of screws, nuts, and Allen keysThe immediate standout is the inclusion of mounting hardware—a thoughtful addition that signals RAK Wireless's commitment to making this device truly user-customizable.The device itself has a substantial feel, continuing the tradition of good build quality from RAK Wireless. The external fit and finish suggest this is a device designed for practical field use rather than just desktop experimentation.However, it's worth noting that unlike the WisMesh Board ONE Pocket which had excellent 3D printing quality, the V2's case quality isn't quite as refined. The mounting screws for the board screw directly into the plastic, which felt a bit sticky during testing and may potentially wear out with repeated use. Despite this, I appreciated the inclusion of screws to easily put together and remove components.Features OverviewThe WisMesh Pocket V2 brings an impressive array of features that position it as possibly the most expandable Meshtastic handheld available:2 sensor expansion: Two accessible sensor slotsDedicated IO slot: Adds even more expansion possibilities beyond sensorsOnboard GPS: Crucially, this doesn't occupy a sensor slot.1.3" OLED display: Larger than the 0.96" screens common on cheaper options, improving readabilityST LIS3DH motion sensor: An interesting addition that hints at future capabilities, though currently not utilized by Meshtastic firmware3200mAh battery with temperature monitoring: A substantial power source with safety featuresBuilt-in BMS (Battery Management System): For safer charging and battery managementSolar connector: Providing off-grid power optionsExternal SMA connector: For antenna customization and range improvementMultiple control buttons: Battery switch, user button, and reset buttonExposed GPIO pins: For advanced users looking to add custom functionalityThe feature set demonstrates a clear philosophy: this is a platform for experimentation and customization, not just a single-purpose device.Flashing the FirmwareThe device comes preflashed with Meshtastic version 2.5.20, but if you want to update it, here's the process:Erase the Existing Firmware:Navigate to the Meshtastic Web Flasher.Select RAK WisBlock 4631 (yeah, I know it's the old board but it works) from the device options.Click on the trash symbol next to the flash button to erase the existing firmware.You'll need to enter DFU mode (Device Firmware Update mode) to proceed.Entering DFU Mode:Option one: Double press the button on the bottom (the one used for reset) and a USB drive should appear on your computerOption two: Click on Enter DFU Mode (After Clicking on Flash and Continue), select the correct COM Port, then click Connect.Erase the Flash in DFU Mode:Once in DFU mode, the WisMesh Pocket V2 will appear as a drive on your computer.Download the Flash Erase UF2 file and copy it to the DFU drive. After transferring, the drive will disappear.Once the device is done rebooting, go back to the web flasher and click on Open Serial Monitor, select the correct COM Port, then click Connect.Give it a couple seconds and it should say done once it is done formatting.Flashing the New Firmware:After erasing the existing firmware, return to the Web Flasher and choose the latest firmware version available.Select Flash, and you will need to enter DFU mode again (repeat the previous step).Once in DFU mode, download or copy the UF2 file for the new firmware onto the DFU drive.The device will automatically reboot once the transfer is complete and will start running the new firmware.The process is straightforward once you know the steps, though having to select an older board model feels like an oversight that could be addressed in future updates.PerformanceBattery LifeThe 3200mAh battery represents a significant upgrade. In real-world testing, the battery lasted an impressive little over three solid days with GPS active and the screen on—a dramatic improvement over the original WisMesh Board ONE Pocket, which struggled to make it through a full day with GPS activated.This extended battery life makes the V2 much more practical for field deployments and multi-day outings without requiring recharging.The battery is also easily accessible once you open the device, which is great if you ever want to replace it in the future.Range & ConnectivityUnfortunately, the range with the included antenna remains disappointing, similar to the original WisMesh Board ONE Pocket. For a premium device at this price point, I expected better out-of-the-box range performance.We got around 500m to 600m from the stock antenna while easily getting 1.8KM on the same environment from the SenseCap T1000E.That said, the external SMA antenna connector remains a crucial feature that separates this device from competitors like the T1000-E. The ability to upgrade to a high-gain antenna substantially increases the device's versatility, even if it requires an additional purchase to achieve optimal range.Screen & Build Quality The 1.3" OLED display maintains one of the strengths. This larger screen size significantly improves the user experience when reading messages or navigating menus compared to the 0.96" displays common on DIY Meshtastic devices.When opened up, the internal build quality is excellent—consistent with RAK's reputation for solid construction. The board components and layout show careful design and quality manufacturing.However, it's hard not to complain about the lack of a buzzer—especially at this price point. With a screen, a buzzer feels almost essential to notify users when a message arrives. You can't expect users to constantly stare at the screen, and if they have to rely on their phone for notifications, it defeats the purpose of having a screen on the device, along with the extra battery drain it causes.Usability & ExperienceThe WisMesh Pocket V2 brings several nice usability touches that make it more user-friendly:The battery switch provides a convenient way to completely power down the device, conserving battery when not in useThe user button offers quick access to device functionsThe reset button is accessible but unfortunately difficult to pressThe indicator LEDs are the same as on the original WisMesh Board ONE Pocket, but disappointingly, they're placed on the bottom of the device. This positioning means they're often not visible during normal use, reducing their utility as status indicators.Another notable drawback: despite the $99 price tag, the V2 still lacks a buzzer for notifications. For a handheld device where users aren't constantly watching the screen, this remains a puzzling and frustrating omission—especially for something positioned as a premium product.The sensor expansion is thoughtfully designed, with slots that are easily accessible once the device is opened. This makes it much more convenient for users who want to experiment with different sensors, encouraging hands-on tinkering and customization.ExpandabilityExpandability is where the WisMesh Pocket V2 truly distinguishes itself from virtually every competitor in the Meshtastic ecosystem. With two sensor slots and an IO slot that are easily accessible, plus onboard GPS that doesn't occupy one of those slots, the device offers unparalleled flexibility.Modular Sensors for LoRaWAN, NB-IoT, LTE-M and other IoT Wireless ApplicationsModular IoT WisBlock sensors that works on LoRaWAN, NB-IoT, LTE-M, WiFi and Bluetooth BLE wireless networks for low power and battery operated IoT applications.The inclusion of multiple sets of mounting hardware transforms the user experience from "can I modify this?" to "what should I modify first?" This approach acknowledges that many Meshtastic users are also makers who enjoy customizing their devices.Some potential expansion scenarios include:Adding environmental sensors (temperature, humidity, pressure)Incorporating air quality monitoringPricingAt $99, the WisMesh Pocket V2 positions itself firmly in the premium segment of Meshtastic handhelds. This represents a significant premium over alternatives, which deserves a closer feature-by-feature comparison:T1000-E (approximately $40): Much more affordable, but offers no customizability, has a no screen, not customization whatsoever, lacks antenna upgrade options (But the range is crazy good out of the box) and way smaller battery yet it performed the same in terms of operating time. Its advantages include water resistance, molded plastic construction, built-in temperature sensor, and a buzzer that the WisMesh Pocket V2 still lacks despite costing more than twice as much.ThinkNode-M1 (approximately $40): Also offers GPS and the ability to upgrade antennas at less than half the price of the WisMesh Pocket V2. It includes a buzzer and a bigger battery, though it can't match the V2's dual sensor expansion capability.T-Deck (approximately $62): can't be customized with sensors unless you want to DIY, and it has a smaller battery, but some versions come with a BME280 sensor (temperature, humidity, and pressure) for even a couple bucks cheaperThe pricing follows RAK's pattern of charging a premium over competitors, but the gap has widened further with this model. The inclusion of solar technology in a handheld device feels like overkill that unnecessarily drives up the cost. For a handheld that will primarily be recharged via USB, the solar components represent features most users won't utilize but still have to pay for.However, none of these alternatives offer anywhere near the expansion capabilities of the WisMesh Pocket V2. For users who will take advantage of the multiple sensor slots and customization options, the price may be justified by the versatility alone. The question becomes: do you need 2 sensor slots and an IO slot in a handheld device? If the answer is yes, the WisMesh Pocket V2 stands alone in the market, regardless of price.For users simply wanting a basic Meshtastic handheld with no plans for expansion, the value proposition is less compelling compared to the lower-cost alternatives that offer 70-80% of the functionality at 40-50% of the price.Final ThoughtsThe WisMesh Pocket V2 represents a significant evolution in the Meshtastic ecosystem, clearly targeted at enthusiasts who value flexibility and expansion capabilities over base price. RAK has created what might be the ultimate modular Meshtastic handheld.At $99, it's positioned at a price point that will likely deter casual users. However, the WisMesh Pocket V2 offers capabilities that simply aren't available elsewhere in a single package.Despite some drawbacks—the still-disappointing stock antenna range, bottom-placed LEDs that are often not visible, lack of a buzzer, and a difficult-to-press reset button—the WisMesh Pocket V2 fills a unique gap in the market. It's undeniably "sexier" than some more cheaper alternatives.I see the WisMesh Pocket V2 as the ideal choice for:Users deploying in environments where customized sensing is valuableThose who prioritize future-proofing and reparability Makers looking to use the device in a versatile setup or connect it to a solar panel later onFor those simply wanting an affordable, basic Meshtastic handheld, the various lower-cost alternatives will likely remain more appealing. But for users seeking the most flexible and expandable option available—and willing to pay the premium for that capability—the WisMesh Pocket V2 establishes itself as possibly the definitive choice in the current market landscape.

Ive been thinking about a generic public services architecture for PierMesh. A BBS, a digital library, an event calendar/registration system and a small publishing platform for media. I think these would be easy to make distributed/widely accessible through both typical technologies and LoRa/Halow. It should be technically simple so almost any device can access it and I think you could run a read only/text only site along with a more robust version easily. I think this might be where I focus for the one box mesh deployment idea. It's very much in line with the idea of disaster preparedness that's part of why I'm so into PierMesh.

This positioning means they're often not visible during normal use, reducing their utility as status indicators.Another notable drawback: despite the $99 price tag, the V2 still lacks a buzzer for notifications. For a handheld device where users aren't constantly watching the screen, this remains a puzzling and frustrating omission—especially for something positioned as a premium product.The sensor expansion is thoughtfully designed, with slots that are easily accessible once the device is opened. This makes it much more convenient for users who want to experiment with different sensors, encouraging hands-on tinkering and customization.ExpandabilityExpandability is where the WisMesh Pocket V2 truly distinguishes itself from virtually every competitor in the Meshtastic ecosystem. With two sensor slots and an IO slot that are easily accessible, plus onboard GPS that doesn't occupy one of those slots, the device offers unparalleled flexibility.Modular Sensors for LoRaWAN, NB-IoT, LTE-M and other IoT Wireless ApplicationsModular IoT WisBlock sensors that works on LoRaWAN, NB-IoT, LTE-M, WiFi and Bluetooth BLE wireless networks for low power and battery operated IoT applications.The inclusion of multiple sets of mounting hardware transforms the user experience from "can I modify this?" to "what should I modify first?" This approach acknowledges that many Meshtastic users are also makers who enjoy customizing their devices.Some potential expansion scenarios include:Adding environmental sensors (temperature, humidity, pressure)Incorporating air quality monitoringPricingAt $99, the WisMesh Pocket V2 positions itself firmly in the premium segment of Meshtastic handhelds. This represents a significant premium over alternatives, which deserves a closer feature-by-feature comparison:T1000-E (approximately $40): Much more affordable, but offers no customizability, has a no screen, not customization whatsoever, lacks antenna upgrade options (But the range is crazy good out of the box) and way smaller battery yet it performed the same in terms of operating time. Its advantages include water resistance, molded plastic construction, built-in temperature sensor, and a buzzer that the WisMesh Pocket V2 still lacks despite costing more than twice as much.ThinkNode-M1 (approximately $40): Also offers GPS and the ability to upgrade antennas at less than half the price of the WisMesh Pocket V2. It includes a buzzer and a bigger battery, though it can't match the V2's dual sensor expansion capability.T-Deck (approximately $62): can't be customized with sensors unless you want to DIY, and it has a smaller battery, but some versions come with a BME280 sensor (temperature, humidity, and pressure) for even a couple bucks cheaperThe pricing follows RAK's pattern of charging a premium over competitors, but the gap has widened further with this model. The inclusion of solar technology in a handheld device feels like overkill that unnecessarily drives up the cost. For a handheld that will primarily be recharged via USB, the solar components represent features most users won't utilize but still have to pay for.However, none of these alternatives offer anywhere near the expansion capabilities of the WisMesh Pocket V2. For users who will take advantage of the multiple sensor slots and customization options, the price may be justified by the versatility alone. The question becomes: do you need 2 sensor slots and an IO slot in a handheld device? If the answer is yes, the WisMesh Pocket V2 stands alone in the market, regardless of price.For users simply wanting a basic Meshtastic handheld with no plans for expansion, the value proposition is less compelling compared to the lower-cost alternatives that offer 70-80% of the functionality at 40-50% of the price.Final ThoughtsThe WisMesh Pocket V2 represents a significant evolution in the Meshtastic ecosystem, clearly targeted at enthusiasts who value flexibility and expansion capabilities over base price. RAK has created what might be the ultimate modular Meshtastic handheld.At $99, it's positioned at a price point that will likely deter casual users. However, the WisMesh Pocket V2 offers capabilities that simply aren't available elsewhere in a single package.Despite some drawbacks—the still-disappointing stock antenna range, bottom-placed LEDs that are often not visible, lack of a buzzer, and a difficult-to-press reset button—the WisMesh Pocket V2 fills a unique gap in the market. It's undeniably "sexier" than some more cheaper alternatives.I see the WisMesh Pocket V2 as the ideal choice for:Users deploying in environments where customized sensing is valuableThose who prioritize future-proofing and reparability Makers looking to use the device in a versatile setup or connect it to a solar panel later onFor those simply wanting an affordable, basic Meshtastic handheld, the various lower-cost alternatives will likely remain more appealing. But for users seeking the most flexible and expandable option available—and willing to pay the premium for that capability—the WisMesh Pocket V2 establishes itself as possibly the definitive choice in the current market landscape.

Like, the problem with making this coms library is that it is inherently integration testing at almost every step. I'm doing a mesh-of-meshes communications library that translate between espnow, ble, and LoRa, every step from the routing to the transmitting is multi device testing. It has made building this out a nightmare because every debug step was like, plug in device, flash device, remove device, plug in device, flash device, plug first device into power, run tests, oh, that didn't report correctly, okay, which device was the issue... Esp32-s3's technically are capable of usb-debugging, but also they're annoying as hell about it. This makes my life way better.

My worker firmware works! It flashed itself over, now just to add some roll back, security, and validation features. But effectively this means I never have to plug in another ESP32 to send them firmware. I can just tell them to post to MQTT from the worker firmware for logging and post the firmware binary to my local file server. This makes my life so much easier while building out this mesh of meshes multi-protocol com lib. Hell yeahhh

This feature optimizes network topology according to specific needs, controls transmission delay, and ensures effective data delivery in complex multi-hop networks, thereby enhancing network flexibility and reliability.

MESH self-organizing network: Developed by NiceRF, the MESH algorithm features automatic routing, forming a network transmission system with no blind spots and no distance limitations.

Precautions for Using High-Power Wireless Data Transmission Radios

Select a suitable DC regulated power supply with strong high-frequency interference resistance, low ripple, and sufficient load capacity. It is also necessary for the power supply to have overcurrent protection, overvoltage protection, and lightning protection functions.

Do not use the radio in environments that exceed its specified characteristics, such as high temperatures, high humidity, low temperatures, strong electromagnetic fields, or dusty conditions. These environments can significantly wear down the radio, shorten the lifespan of internal components, and cause substantial signal attenuation in strong electromagnetic environments, hindering wireless signal transmission.

The ground wire of the data transmission radio should be well-connected to the ground wire of external devices (such as PCs, PLCs, etc.). Otherwise, it can easily damage the communication interface or cause signal transmission instability, leading to errors and other issues.

Antenna Selection Precautions for Data Transmission Radios

To ensure optimal communication distance for the module, follow these principles during antenna usage:

Antenna Positioning: Avoid placing the antenna close to the ground surface and keep it away from obstacles.

Magnetic Base Antennas: If using a magnetic base antenna, straighten the lead wire as much as possible, and attach the base to a metal object.

Yagi Antennas: For Yagi antennas, it is recommended to place the transmitting antenna vertically and the receiving antenna horizontally.

Note: Due to the high power output, ensure the antenna is connected before the radio starts transmitting to avoid damaging the internal power amplifier module.

Antenna Distance: The distance between the receiving and transmitting antennas should be greater than 1.5 meters.

Top IoT powered building automation protocols you must be aware of

https://www.zenatix.com/top-iot-powered-building-automation-protocols-you-must-be-aware-of/

At present, there are more than 12.2 billion active global IoT connections. These interconnected devices communicate with each other and produce meaningful data. However, only communication is not enough. They need to speak the same language. It’s the point where IoT protocols come to use!

What are IoT protocols?

A protocol is a set of rules that allows for the effective communication (i.e., data exchange) of distinct machines/devices in a network setting. The protocols also apply to the Internet of Things (IoT).

Why do IoT Protocols matter?

IoT protocols give smart systems the ability to communicate with each other seamlessly. Moving data from endpoint devices through the IoT pipeline to central servers becomes a matter of a few minutes with IoT protocols.

It is only IoT protocols that make sure data sent from endpoint devices, such as sensors, is received and understood by the subsequent steps in the connected environment. They are as critical to the existence of IoT as the things themselves.

Though protocols work collectively to make IoT work, not all of them are created equal. Some IoT protocols work well in buildings, while some are well suited for IoT deployments spread among buildings.

Some popular IoT Protocols

Several IoT protocols enable either device-to-device, device-to-gateway, or device-to-cloud/data center communication — or combinations of these communications. Here are some of the most common and popular IoT protocols:

BACnet

BACnet is a communication IoT protocol for building automation and control (BAC) networks. It’s designed to enable communication of building automation and control systems for applications including heating, ventilating, and air-conditioning control (HVAC automation systems), lighting control, access control, fire detection systems, and other building equipment.

BACnet provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform. It’s mainly used in building automation systems (BAS) to control the data exchange between different devices and components.

The top features of BACnet include:

Open source standard

No license fee for implementation

Adopted by a large number of manufacturers, making them less dependent on a specific vendor for their implementation

BACnet fulfills all the merits of a standardized protocol.

Modbus

Modbus protocol is used for transmitting information over serial lines between electronic devices. This open protocol is widely used by many manufacturers throughout many industries. It transmits signals from instrumentation and control devices back to the main controller or data-gathering system.

Since it’s openly published and royalty-free, this IoT protocol is popular in industrial environments. It is relatively easy to deploy and maintain as compared to other standards. In the field of process automation and SCADA (Supervisory Control and Data Acquisition), Modbus is the most popular and oldest automation protocol.

OpenThread

Released by Google, OpenThread is an open-source implementation of Thread. It comes with specifications that define an IPv6-based reliable, secure, and low-power wireless device-to-device communication protocol for home and commercial building applications.

Top features:

IPv6 configuration and raw data interface

Extending Thread mesh over Ethernet/Wi-Fi links

Bidirectional IPv6 reachability and DNS-based service discovery between Thread and Ethernet/Wi-Fi

UDP sockets

CoAP client and server

DHCPv6 client and server

DNSv6 client

Child Supervision

Inform Previous Parent on Reattach

Jam Detection

Periodic Parent Search

This IoT protocol is highly portable that supports both System-on-Chip (SoC) and Co-Processor (RCP, NCP) designs.

LoRaWan

LoRaWAN is a Low Power Wide Area Networking (LPWAN) communication protocol that functions on LoRa. Anyone can set up and operate the LoRa network.

It’s designed to wirelessly connect battery-operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility, and localization services.

Top features:

Long-range communication up to 10 miles in line of sight

Low cost for devices and maintenance

License-free radio spectrum but region-specific regulations apply

Low power but has a limited payload size of 51 bytes to 241 bytes as per the data rate, which can be 0,3 Kbit/s – 27 Kbit/s data rate with a 222 maximal payload size.

The rise of IoT is giving rise to radical changes in how devices communicate with each other. IoT protocols will help increase in adoption and importance as the number of connected devices rises.
