MQTT command for standby mode (no ventilation) #6

Rejo007 commented 2026年03月17日 07:19:17 +01:00

Hello,

I’m currently integrating the device via MQTT and I’m looking for a way to keep it powered on while disabling the ventilation (essentially a "standby" mode).

Is there an available MQTT command, topic, or payload that allows:

keeping the device ON

but setting fan speed to 0 or disabling airflow entirely

If not, is there a recommended workaround (e.g. a specific mode or state) to achieve this behavior?

Any documentation or examples would be greatly appreciated.

Thank you!

Typically the HA/MQTT integration is done with the Faikout module, and the Remote will mirror the setting changes it sees.

hello,
thanks
integration is done but i would like to set fanrpm":[580,581,590] to 0 and keep power on.

Yeh S21 does not send an rpm, it sends low/medium/high maybe auto or night mode depending on model.

I don’t think there is an S21 message to say "off" other than turning off the unit as a whole. Surely fan off would be the same though, as no fan means no compressor running either as no air circulation to extract/inject heat...
