Command ID 16

Post by minocz73 »

Hello,
I understand correctly that Opentherm gateway firmware does not contain the command ID 16 - W Room Setpoint Current room temperature setpoint (° C)? If not, can this command be added?
Thank you Marek

What exactly are you looking for? The Current Room Setpoint is something a thermostat may indicate. If it does, the OTGW will report it and/or store so it can be included in a summary report. So there is support for MsgID 16.

If the thermostat does not send MsgID 16, then the OTGW has no way of knowing what the Current Room Setpoint is. That's not normally a problem, because boilers generally have no need for this information.

Hello
Thank you very much for your advice. I'm so sorry I'm this beginner. This log generates a room setpoint change of 17 ° C. Can you please send me the procedure to change the room temperature using the Opentherm gateway?
Thank you Mark

Sorry, but I still don't understand what you want to do.

Initially you asked about the Room Setpoint, MsgID 16. Now you talk about Room Temperature, which is MsgID 24.

The log shows the thermostat sends a Room Setpoint of 17. There is no setpoint change. Are you referring to MsgID 9 (Remote Override Room Setpoint) with that remark?

Do you want to change the value in MsgID 16 that gets sent to the boiler? As I mentioned before, boilers don't normally use that information. So, even if you could change the value, it would be unusual for it to have any effect.
