I am using the following scene to set my two thermostats. However, the fan mode does not change if I set it as part of a scene. However, I can explicitly call set_fan_mode and it works…
Interesting timing as just yesterday we had our air conditioning controller upgraded. Same physical air conditioner but changed from MHI controller and intesis wifi module to izone (My Zone 3) controller and thermostats.
Heaps better control and integration with home assistant but still the fan speed cannot be changed with scenes. Weird.
