@timnolte It’s been an ongoing effort to “invest” in devices that have long-term (+10 years) life AND good HA community support. I was an early adopter of Insteon, ISY994, etc (before HA existed) and happy to see this community provide integration support but I started replacing my Insteon stuff when the devices started to fail and it seemed Insteon was coming to its end-of-life. Insteon appears to be going away now but the community is still supporting it. 
Honeywell thermostats have been around forever, appear to be a long-term device, and have never given me any problems (I have never had to replace one that failed) but the HA Honeywell Integration support has been lacking. And I’m not a fan of Resideo/Honeywell cloud service/API.
I too would love to have what you are looking for but also include long-term hardware and HA support. Let me know if you find it.
P.S. There are some great discussions about this under other topics like Zigbee vs Z-Wave vs WiFi
