Hello there, I’ve this MVHR system from Zehnder that I can set via Comfosense 67 which is basically a 4-position switch.
Was wondering if anyone has been able to interface to the Comfosense and integrate into HA to be remotely controlled.
Any tips on the technical possibility to interface is highly appreciated!
Hi,
I’ve also have a ComfoSense controling a Comfoair 200.
I’ve automated the comfoair 200 with GitHub - wichers/esphome-comfoair: ESPHome configuration to drive Zehnder ComfoAir devices.
In order for the COM interface to work, the comfosense must be turned off.
Hey there, actually I was able to proxy the comfosense to use it also with the esp32, I can use both regardless.
You can find here: Zehnder ComfoAir CA350 integration via serial connection (RS232) and MQTT - #443 by samumar my simple schematic to wire everything up and the code I used for reference.
I hope this might be useful also for you!
And we can close the topic
