We recently installed a split system with 4 indoor units, and added 4 honeywell wifi thermostats for remote temperature control. I then wanted to connect the thermostats to Google Home app. but I found out that no matter what I don, only one of the 4 thermostats is visible to Google Home app. Is there something I can do to make all 4 thermostats visible in the Google Home app?
Two things happened since I posted the question.
- A few months after the post, the thermostats suddenly all started appearing in the integration.
- Sadly it turns out that the Honeywell thermostats don't really work: they don't measure the temperature reliably, nor do they control the AC reliably. Digging a bit deeper found dozens of people complaining of the thermostats not working.
I ended up throwing the Honeywell smart thermostats away and buying Cielo devices instead. They work much more reliably and predictably. With that, the issue went away.
