Siri controlling Thermostat with wrong command
Noticed in latest iOS 11 betas that if I issue a 'set thermostat to 72 degrees' command through Siri that rather than just adjust the temp it now changes from cooling mode to Heating & Cooling every time. Whether you issue the command through Siri on an iPhone or Apple TV, same thing. If you use a HomeKit app and just adjust the temp, all good, just sets temp and doesn't adjust cooling mode.

Anyone else seen this and or know about the issue ?

Raised a bug on this and will also reach out on the homebridge-nest forum

Thanks as always
