I’m using a Moes BRT-100 (TS0601) connected through Zigbee2MQTT.
When I turn the thermostat off via a Gladys scene (sending {"preset": "frost_protection"} or {"system_mode": "off"} through the “Zigbee2MQTT message” action), the command never reaches the device – the valve keeps heating.
However, if I set the same command directly in the Z2M UI (device → set), it works perfectly, and Gladys then correctly shows the state as “off”.
So the issue seems to be on the Gladys → Z2M side. Is there a known problem with the “Zigbee2MQTT message” scene action, or am I missing something in the configuration?
