Wyze Thermostat multiplying on Google Home

I’ve been living with this for a while and it’s about time I fix it.

I installed a Wyze Thermostat a number of years ago and it has always worked with our Google smart speakers. But, at some point Google started responding to our commands with " Yada Yada two devices. One device not available…"

Well, This week it went up to three devices and I still have no idea why. Anyone have any clues?
