Assist not working with thermostats

Hello,

I have two thermostats that work partially with Alexa. But when I ask Assist to do anything with “Thermostat - Downstairs” it says it “Sorry I am not aware of any device called thermostat downstairs”. Assist works with all my other devices I’ve tried, not sure what’s causing the problem with the thermostats. Maybe the hyphen?

-Thanks

Probably… Just add an alias to each entity without the hyphen.

Thank you, the hyphen was the culprit. I was not aware you could set aliases for devices. Very good to know!
