The frient Electricity Meter Interface 2 LED is a small device that you can attach to the LED of your smart meter. It counts the light pulses of the LED and sends the data to your smart home system via Zigbee.

Pros

• No electrical installation necessary: You don't have to be an electrician to install it. Just stick it on your meter.
• Covers the complete energy consumption: It measures the total energy consumption of your household, including devices like your washing machine in the cellar.

Step-by-step guide for setting up Zigbee2MQTT with Docker

Zigbee2MQTT is an open-source software that allows you to connect your Zigbee devices to your smart home system via MQTT. Here is a step-by-step guide on how to set it up with Docker.

Prerequisites

• A server with Docker and Docker Compose installed.
• A Sonoff Zigbee 3.0 USB Dongle Plus.

1. Create a docker-compose.yml file

Create a new file named docker-compose.yml with the following content:

version: '3.8'
services:
  zigbee2mqtt:
    container_name: zigbee2mqtt
    image: koenkk/zigbee2mqtt
    restart: unless-stopped
    volumes:
      - ./zigbee2mqtt-data:/app/data
      - /run/udev:/run/udev:ro
    ports:
      - 8080:8080
    environment:
      - TZ=Europe/Berlin
    devices:
      - /dev/ttyUSB0:/dev/ttyACM0

Note: You might need to change the devices mapping depending on your system. You can find the correct device with the command ls -l /dev/ttyUSB* or ls -l /dev/ttyACM*.

2. Start the container

Start the container with the following command:

docker-compose up -d

3. Configure Zigbee2MQTT

Open your browser and navigate to http://<your-server-ip>:8080. You should see the Zigbee2MQTT frontend. Now you can start pairing your Zigbee devices.
