Thermostat not receiving commands from OTGW

[aferrato]

Hi,
I have a Beretta METEO GREEN AND 30 C.S.I. boiler and a BeSMART thermostat from Riello, I connected an OTGW bought from Nodo between the two and I can read the messages they exchange.

The problem is that I cannot control the thermostat with the otmonitor, if I send a Setpoint command the thermostat does nothing.

Is there anything I can do to find the problem or does it mean that my thermostat does not accept opentherm commands?

thank you.

Thermostats don't accept commands. They send commands (requests) and receive responses. If a thermostat never sends a request for a setpoint change (MsgID 9), then the OTGW doesn't get an opportunity to send this information on to the thermostat. So, check the summary tab in otmonitor to see if MsgID 9 is listed. Some thermostats have a menu setting to enable this functionality. If neither of these two is available, then this feature won't work with your thermostat.

Most thermostats that can be controlled via an app, like the BeSMART, will not offer this functionality via the OpenTherm interface. Presumably because you can already do it with the app. Which doesn't mean that all thermostats without an accompanying app support it.

Thank you for the reply!
I am slowly learning how opentherm works.

this is what I see in the summary tab, there is no MsgID 9:

the last page of this manual https://www.vokera.co.uk/wp-content/upl ... Manual.pdf lists the settings that I can change, but I don't see this functionality.

at this point I think there is no way to use this thermostat .
