I have a number of devices that can’t integrate with Hubitat, but my Mysa baseboard thermostats are top of mind. I have multiple thermostats in multiple rooms.
What is the best/“correct” way to bridge this integration? The Mysa work with both Google home and HomeKit, and with HomeKit being local that sounds most appealing.
Do I need to create a virtual device for every single Mysa? Can I set this virtual device to a number, then have Mysa mimic it on the other end? Or do I have to do more of a “heat on” / “heat off” sort of device toggle?
I think you might be able to get it fully into HE, via HomeKit, but only if you use Home Assistant as the apple home hub HomeKit Device - Home Assistant . Then you would have to use another app/plugin to share it to HE.
Other than that I think you only option would be to use a virtual switch just for on/off as you said, either a group tied to one or a switch for each one. I dont think there is a way to pass values back and forth due to the automation limitations of the other platforms.
Is there a reason why Home assistant can fully control the homekit device, but hubitat (with it's new non-beta homekit integration?) cannot? I'm not at all familiar with that side of things
It is two different types of integrations. The new HE integration is to make HE act as a HomeKit bridge which allows you to share devices from HE to HK. Home Assistant also offers an integration like this.
The integration I linked to for Home Assistant is different, where HA takes on the role of an actual home hub I think (similar to an Apple Home Pod). So you are actually pairing the devices to HA directly, with apple Homekit pairing. I suspect it is a reverse engineered design, somewhat experimental and could be broken by apple at any time.
