Porting of Keenect to Hubitat?

No problem, 2 things: I switched to the nst integration app for long term, personally. And I refactored keenect to this Keenect Lite (Release)

It is a lot simpler in code and usage. You use your nest/household thermostat in the master, and create a virtual thermostat for each zone.

I will continue to support this version, but if there is any future development, I will do it in the lite version.
