Hi @emil, thanks for asking.
My ideal setup would be modular hardware - perhaps design the units so that they can be strung together with wired connectors and presented to the cloud as 1 unified unit.
The reason I don’t want to install multiple separate units today is that the additional hardware required for common wire sharing drives up cost and complexity - and it just looks messy too. When I sell my home I want it to look right.
I think such an arrangement could open up a some commercial markets for you too.
Presumably, it should be fairly easy to refactor the software for additional zones.
