Domoticz

Hello,
I have developed domoticz plugin which helps me integrate my ThesslaGreen recuperator over RS485 modbus connectivity (available even as basic functionality of the device).
https://thesslagreen.com/product/airpack4h/
Plugin should work with all AirPack family models, however was tested only with AirPack4 500h

supported functionality -
reading temperature: outside, supply, exhaust , fpx, duct_supply, gwc, ambient
reading AirFlow: supply and exhaust

Possibility to turn on/off, read/set special flow mode.

Plugin is available to download from
https://github.com/voyo/ThesslaGreen-modbus

Thanks for the plugin! I added it to the wiki https://www.domoticz.com/wiki/Plugins

Yes, it's possible to add a selector switch for manual airflow levels.

However, I'm not sure I'd use it myself, so my motivation to implement it is pretty low. In my setup, I keep the unit running at 10% constantly (off at night), and just hit the ventilation button manually when needed for a quick boost.

If you have a specific use case where scheduled airflow changes would be useful, let me know - might change my mind.

New version available on github -
Fixed negative temperature readings for outside_temp and fpx_temp sensors in pymodbus mode.
