[SOLVED] MAP function or oder to connect Max! Thermostat "Mode" to Dummy item for Google Home interaction

Can someone tell me what is the Alexa voice command to switch the Homekit:HeatingCoolingMode?

Say, to switch a thermostat to off?

Dear all,

I have a strange issue:

“Alexa, turn the heating to 22 degrees” - > “Thermostat heating is set to 22 degrees”
“Alexa, switch the heating off” -> “Thermostat heating does not support this”
(from German)

Can anyone help? Please check Thermostat works well in Google Home, but not with Alexa
