This plugin is free and open source, you can use forever and any purpose you like. But further improvement is stopped.

The new script which adds Shelly devices to Domoticz MQTT Autodiscovery hardware is published at https://github.com/enesbcs/shellyteacher4domo and that is currently under development.

ShellyMQTT - Domoticz Python Plugin

Python plugin for Shelly relay devices using MQTT protocol

MQTT parts based on heavily on the [zigbee2mqtt] project (https://github.com/stas-demydiuk/domoticz-zigbee2mqtt-plugin) big thanks for it!

Prerequisites

Tested and works with Domoticz v4.x.

If you do not have a working Python >=3.5 installation, please install it first! ( https://www.domoticz.com/wiki/Using_Python_plugins ) (if Shelly_MQTT does not appear in HW list after installation, read again the above article!)

Setup and run MQTT broker and an MQTT capable Shelly device. (http://shelly-api-docs.shelly.cloud/#mqtt-support-beta) If you do not have an MQTT server yet, install Mosquitto for example: http://mosquitto.org/blog/2013/01/mosquitto-debian-repository/

!!! Please, DO NOT CHECK "Use custom MQTT prefix" on your device settings page if you want to use this plugin as this will render device detection unusable !!!

!!! For Shelly Plus HT, please prefix the MQTT topic with shellies/ on your device settings page to make it send on the same topic as other devices !!!

Installation

1. Clone repository into your domoticz plugins folder

cd domoticz/plugins
git clone https://github.com/enesbcs/Shelly_MQTT.git

2. Restart domoticz
3. Go to "Hardware" page and add new item with type "ShellyMQTT"
4. Set your MQTT server address and port to plugin settings
5. Remember to allow new devices discovery in Domoticz settings

Once plugin receive any MQTT message from Shelly it will try to create appropriate device.

Plugin install&update with plugin manager

I suggest to use a plugin manager for easy updates through Domoticz GUI: https://github.com/stas-demydiuk/domoticz-plugins-manager

Plugin manual update

Warning: if you use this method, Domoticz may duplicate devices after it!

1. Stop domoticz
2. Go to plugin folder and pull new version

cd domoticz/plugins/Shelly_MQTT
git pull

3. Start domoticz
