Hey Joel!
The RTH9580WF should work! I have three on my desk that I’ve been working with. Just tap the Honeywell 9000 and tap “+ Connect New Device”
@dshokouhi I’m glad to hear that the 8580WF connected!
There are a few issues that we still need to sort out, unfortunately. You can find the most serious ones listed in my post here: Honeywell RTH9580WF is ready
Let me know if you have any questions or problems!
