DIY: Easiest Standalone Deauther

Previously, I have built a standalone Deauther with an OLED display and buttons over here, but realistically, everyone is just going to use the web interface. So, I recently found an ESP8266 ESP-07 USB module that is perfect for a standalone Deauther, since it has a USB connector built-in and you can just plug it into any powerbank. This module cost me around USD3 and you can find it in AliExpress.

First, we need to download the Deauther firmware. Go to this page and download this file: esp8266_deauther_2.6.1_DSTIKE_NODEMCU_07_V2.bin

Next, set the switch on the ESP module to "PROG" and plug it into your computer's USB. Run Google Chrome or Microsoft Edge browser and go to https://esp.huhn.me. Click CONNECT and select the USB Serial item and click Connect.

Now that it has successfully connected, click SELECT and choose the firmware file you downloaded earlier, then hit the PROGRAM button.

It should now start flashing, so just let it finish the job.

Finally, flick the switch on the ESP module from PROG to UART, and hit the reset button on the ESP module while still plugged into USB, or you can just remove it from your computer and plug it into a powerbank. On your phone/computer, just connect to the Wifi network "pwned" and use "deauther" for the password. Then open your web browser and go to http://192.168.4.1

That's it! You now have a standalone Deauther. More information about using the web interface over here. Also, realize that in most countries, there are laws against disrupting communication networks and Deauth attacks may be illegal.

DIY Smart Home Energy Monitor with ESP32 and Home Assistant

Introduction

Managing energy consumption is a great way to reduce electricity costs and contribute to environmental sustainability. With the help of IoT, you can monitor energy usage in real-time, right from your smartphone. In this guide, we’ll build a Smart Home Energy Monitor using an ESP32 microcontroller, current and voltage sensors (like the ACS712 or SCT-013), and the MQTT protocol for data transmission. This data will be accessible on a mobile app via Home Assistant, allowing you to keep track of energy usage and optimize it effectively.

Project Overview

Objectives

Monitor power consumption in real-time for home appliances.

Display energy usage on a mobile app using MQTT and Home Assistant.

Analyze data over time to make informed decisions about energy usage.

Key Components

ESP32 (or ESP8266) microcontroller: For reading sensor data and connecting to Wi-Fi.

Current Sensor (SCT-013 or ACS712): For measuring current drawn by appliances.

Voltage Sensor: Optional, but adds more accuracy if you want to measure precise power usage.

MQTT Protocol: To send data to Home Assistant for real-time monitoring.

Home Assistant: A home automation platform to display and analyze data.

Part 1: Setting Up the Components

1. ESP32 or ESP8266 Microcontroller

Choose either the ESP32 or ESP8266 microcontroller. The ESP32 has more features and is preferred, but either will work.

Connect the ESP32 to your computer using a USB cable to program it.

2. Current Sensor (SCT-013 or ACS712)

SCT-013 is a non-invasive sensor that clamps around a wire to measure the AC current flowing through it.

ACS712 is a current sensor that can measure both AC and DC current but requires direct connection to the wire, so exercise caution with high voltage.

Wiring for SCT-013

Connect the SCT-013 sensor’s output to an analog input pin on the ESP32.

If you’re using SCT-013 with ESP8266, you’ll need an analog-to-digital converter (ADC) module since the ESP8266 has only one analog input pin with limited resolution.

Wiring for ACS712

Connect the VCC pin to the 3.3V or 5V pin on the ESP32.

Connect the OUT pin to an analog input pin on the ESP32.

Connect the GND pin to the ground (GND) on the ESP32.

3. Voltage Sensor (Optional)

A voltage sensor can be added to measure the actual voltage if you want to calculate power more accurately.

Connect the sensor’s VCC to the 3.3V on ESP32, GND to ground, and OUT to an analog input.

Part 2: Coding the ESP32 for Data Acquisition and Transmission

1. Install the Required Libraries

Make sure you have the following libraries installed in your Arduino IDE:

ESP32 or ESP8266 board support (depending on your microcontroller)

PubSubClient library for MQTT communication

WiFi library for connecting to your Wi-Fi network

2. Set Up the Code

Here’s the code to:

Read values from the current sensor.

Calculate power consumption (voltage x current if you have a voltage sensor, or assume constant voltage).

Publish data to an MQTT broker.

#include <WiFi.h> #include <PubSubClient.h>

// Wi-Fi and MQTT Broker Settings const char* ssid = "YOUR_SSID"; const char* password = "YOUR_PASSWORD"; const char* mqtt_server = "YOUR_MQTT_BROKER_IP";

// MQTT topics const char* topicPower = "home/energy_monitor/power";

WiFiClient espClient; PubSubClient client(espClient);

// Sensor parameters const int sensorPin = 34; // Analog pin for sensor (ESP32) const float voltageCalibration = 230.0; // Voltage in volts (modify as per your region) const float sensorCalibration = 0.185; // Calibration constant for ACS712 sensor

void setup() { Serial.begin(115200); setup_wifi(); client.setServer(mqtt_server, 1883); }

void setup_wifi() { delay(10); Serial.println("Connecting to WiFi..."); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500);

Serial.print("."); } Serial.println("Connected to WiFi."); }

void reconnect() { while (!client.connected()) { Serial.print("Connecting to MQTT..."); if (client.connect("ESP32Client")) { Serial.println("Connected."); } else { delay(5000); } } }

void loop() { if (!client.connected()) { reconnect(); } client.loop();

// Read sensor data int rawValue = analogRead(sensorPin); float current = rawValue * sensorCalibration; // Adjust based on sensor

// Calculate power float power = voltageCalibration * current; // Simple power calculation (P=VI)

// Publish data to MQTT String powerStr = String(power); client.publish(topicPower, powerStr.c_str()); Serial.print("Power: "); Serial.println(power); delay(2000); // Send data every 2 seconds }

3. Upload Code

Connect your ESP32 to your computer.

Select the correct board and port in the Arduino IDE.

Upload the code to the ESP32.

Part 3: Setting Up Home Assistant and MQTT Broker

1. Set Up MQTT Broker

If you don’t have an MQTT broker, you can use Mosquitto on your local network or use an online MQTT service like HiveMQ.

Install Mosquitto on a Raspberry Pi or a computer running Home Assistant.

Configure Mosquitto by setting a username and password for secure access.

2. Configure Home Assistant

In Home Assistant, you’ll add the MQTT integration to receive data from the ESP32.

Go to Settings > Integrations and search for MQTT.

Enter your MQTT broker details and save the configuration.

3. Add a Sensor in Home Assistant

In your Home Assistant configuration file (configuration.yaml), add the following entry to display power data:sensor: - platform: mqtt name: "Home Power Consumption" state_topic: "home/energy_monitor/power" unit_of_measurement: "W" value_template: "{{ value | float }}"

Restart Home Assistant to apply changes.

You should now see a Home Power Consumption sensor in your Home Assistant dashboard.

Part 4: Testing and Using the Energy Monitor

Power on your ESP32 and ensure it’s connected to Wi-Fi.

Open Home Assistant, where you should see the real-time data of power consumption.

Monitor the data over time and optimize energy usage based on the data.

Conclusion

With this DIY Smart Home Energy Monitor, you can track power usage across various appliances in your home. This project introduces core IoT concepts such as data acquisition, MQTT communication, and integration with Home Assistant. You can further expand this setup by adding more sensors or even automating appliances based on usage patterns.

DIY: ESP32 Cam + ESP8266 Combo Flipper Zero Module

Here is my project for this weekend, a Flipper Zero module with both ESP32 CAM and ESP8266 D1 Mini combined. This allows me to use it for Marauder, Deauther, WiFi Scanner, Camera, Morse Flash, etc. in a single module. I did consider doing a Mayhem board with NRF24/CC1101, but I find myself rarely using them and Flipper has CC1101 built in anyway (just with shorter range).

The steps to build it is relatively simple. It just combines the two separate modules and some switches to switch between between the two. Below is a quick guide on how I build it. Note that this is not meant to be a detailed step by step tutorial. If you have some experience with building electronic projects, you should be able to follow along.

Build Steps

Start by cutting the prototype board to the required size and the header pins to the correct lengths (8 & 10 pins). Adjust the position of the plastic thingy holding the male header pins, then bend the pins.

After that, we solder all the header pins to the prototype board and also start soldering the required wires. See the references at the end of this post for all the wiring you need to do to connect the necessary pins.

I used four DPDT switches to switch between the 2 modules. All the required connections from Flipper goes to the switches, then from the 2 poles of the switches to the 2 modules. The same with the antenna as well, as I didn’t want to have 2 separate antennas.

Now is a good time to use a multimeter to check all the connections are good and that there no shorts.

Lastly, we use hot glue to hold the antenna cables securely to the prototype board. Here’s what the completed module looks like.

Now we just need to attach the antennas and insert the ESP32 Cam and ESP8266 modules. Oh, and if you have not mod your D1 Mini to use an external antenna, read this. Flash all the required firmware and test!

Next project, designing and 3D printing a case for this module.
