Does anyone have any recommendations for integrating a bathroom ventilator master switch into HA. It is a constantly running ventilator fan that boosts based on a switch or humidistat setting which is controlled on the fan itself. I think its very loud when boosted so I’d like to be able to enable/disable it based on time of day or presence information from HA
Any ideas?
The easiest way is probably to use an ESP32 / ESP8266 and hook up a relay. Be careful around high voltage, only certified trained personal should handle that.
Flash ESPHome onto it, use the switch component, connect 3 jumper wires to the relay, bypass the humidistat and you’re basically done.
If you want to get fancy about it, you could even hook up the “master switch” and have the humidity sensor as a speed setting in a speed fan.
Hi,
It is a more simple if you use SonOff basic or similar wifi enabled relay,
Then you can program on/off schedule directly on it, or integrate it to home assistant like I do.
I turn the fan on/off using a home assistant thermostat based on the current humidity level that I read from a temp/humidity sensor, and the desired target/comfort humidity level that I can adjust directly from HA user interface.
Hope this gives you some inspiration.
Please ket me know if you have any questions
Kind regards,
