I definitely wouldnât recommend putting a safety device into a hybrid HomeKit/Hubitat setup. Join them directly to Hubitat.
If you just want to see their status in HomeKit, thatâs a different story, but donât rely on HomeKit connections for the device itself. Not stable enough.
An exception to devices of almost any kind on another hub would be HA with Home Assistant Device Bridge. Thatâs been very stable for more than two years now.
