Digoo DG-R8H Temperature Sensor

5

I have gotten the Digo DG-R8H working on OMG.
I have made a plug-in (that still needs patching up) based on:

Here is what I cobbled together for my Domoticz setup:

/*
OpenMQTTGateway - ESP8266 or Arduino program for home automation

Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal and a MQTT broker
Send and receiving command by MQTT

This gateway enables to:

  • receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data

  • publish MQTT data to a different topic related to received 433Mhz signal
