HomeGW Climate

I'm currently using a cheap 433MHz Wireless sensor to monitor several rooms in the house.

Attached to my RPi3 running HA I've got an Arduino working as a gateway. The code running in the Arduino is provided here.

The serial sensor receives a payload similar to:

{"dev":"digoo","id":8,"ch":3,"batt":1,"temp":20,"hum":56,"raw":"0x8a0c8f38"}

Using the serial sensor platform and a MQTT binary sensor I've created the homegw_climate custom component that looks like a thermostat, but cannot act upon the HVAC.

The platform supports filtering by channel (ch) which is the only parameter the device provides configuration for.

HomeGW Weather

The weather station is by all means a copy of the climate platform (or the other way round). The same serial sensor is monitored, only the Wireless sensor is different.

HomeGW Cover

This is a cover platform on top of 2 relays exposed through MQTT. Each relays is closed for the duration in milliseconds publish to the control topic. delay_time indicates the time needed to go from 0% to 100% cover. Albeit the name, it is not related to the hardware supporting weather and climate components, for more information on this backend see home_mqtt.

Example configuration

- platform: home_mqtt
  covers:
    living_room:
      relay_up: 1
      relay_down: 2
      delay_time: 17000
    suite:
      relay_up: 3
      relay_down: 4
      delay_time: 17000
