[RELEASE] Home Assistant Device Bridge (HADB)

How to do it is in the quote from me you posted above

If you want to use a button device that cannot be joined directly to Hubitat, you should check out the Hubitat Integration from @jason0x43. It does the opposite of this integration and imports Hubitat devices to Home Assistant. With Jason's integration, you can create Hubitat virtual switches and share them with HA. Next, you would create an automation for each button in HA, so when a button on the device joined to HA is pressed, that will activate the virtual switch in Hubitat.
