Smart home skill thermostat set custom mode

[nidhishbhavsar]

Hi,
I am integrating smart home skill for my thermostat, Smart home skill support COOL, HEAT, AUTO, OFF mode of my thermostat but I have two additional mode names "Fan Only" and "Emergency heat". By researching, I found there is a way to define CUSTOM mode by which I can handle user-defined custom mode.

How can I register my custom "fan only" and "Emergency heat" mode? Do I need to tell Amazon or Is there any configuration in skill or lambda? Please help.

Thanks in advance!

I have a similar issue, how can I set fan mode of the thermostat?
In Gactions, they supported that via action.devices.traits.FanSpeed( https://developers.google.com/actions/smarthome/traits/fanspeed), I did not find anything similar in Alexa, so sad.

+1.
My AC also supports FAN-only mode and DRY mode (AKA dehumidify mode).
I need a mechanism to support these in my skill.
