IRC with KNX switch -> Adjusting comfort temperature

[Mykel]

Hello everyone,

I just wanted to ask if someone has succesfully implemented integration between loxone's IRC block and a KNX thermostat in that way that it would be possible to change comfort temperature from thermostat and the current setpoint would be synchronised between the loxone visualisation and thermostat display? I have succesfully done such synchronisation and control of manual mode temperature, but if I try to use Tc input for comfort temperature I get a following error: everything is fine until I adjust comfort temperature on loxone by pressing + or - icon, then happens as follows: initial setpoint 25C, + pressed and the setpoint output goes to 25,5, then that output goes to the input of the setpoint of thermostat, then the thermostat gives an output of its current setpoint (25,5) to loxone again, but this time, for some reason, loxone adds up 0,5 again, and now the setpoint is 26 and the loop goes on and on, sand similalry with - button but this time if just goes to the negative side. How can I avoid this, what are possible solutions?

Thank You.

I have a similar problem with a vacation mode control on my heating pump. Controlled with modbus and inputs and outputs connected to a +- switch. Often jumps one day extra when a value is changed with input from modbus.

sounds like you have a feedback loop in your logic - almost everyone else who tried to do something similar ends up with the same

You are using the same group adress for "setpoint" temperature in Loxone IRC and knx device. You should use 2 different
