I want to integrate ventilation ventik, working on the protocol modbus rtu in home assistant. My equipment is raspberry 4b with usb stick. I managed to change the speed, but I can’t set the target temperature, since it has the data type holding, and the current input. I wrote such code according to the modbus documentation. I see the current temperature, I can change the ventilation speed, but I can’t set the target. Can you help?
Why would you want to write the temp ?
Usually temperatures are only read especially from a ventilation unit.
Temperatures are set in thermostats…
Because the ventilation has an electric heater and it is necessary to record the target temperature so that it maintains it
AH, Thats a new one 
Can you paste the complete yaml?
