for ahu facility i’m considering this product:
ATR444 | Regolatore PID 48x96mm

and to control it via modbus. This way i also have an alternative way to set up instead of using home assistant.

Hi there, it seems that the ATR444 is not really suitable for flexible AHU unit control.

But as an update i gave up on waveshare esp32 industrial and started installing a waveshare relay modbus module to start control the pumps which controls were broken on my old honeywell eagle.
And of course i have integrated it inside home assistant.
