Using Homey APP / HA integrations?

Hi

I’m hoping to have the following questions answered, apologies if they have been but wasn’t able to find them to my specifics:

  1. Has anyone used HA /w Homey STD or PRO for Airtouch 5 AC control and HDL Buspro lighting & automation control?

  2. Does the Homey APP provide the ability to customise pages and group devices by area/zone or living room lights, AC, blinds etc and set each instance of the ApP to a different landing page ie living room?

I’m trying to find a way to use an APP that is easy to use and look good and not build a UI from scratch or modify an existing template so open to other options also.

Also, does any 3rd party offer the service to write the “drivers” for unsupported brands/systems for Homey that you could suggest? Again, don’t have the time or bandwidth atm to do myself.

Thanks in advance
