I don't know how much other people would value observability, but I feel blind without it.
I would like it too.
Most of these Home Automation product companies seem to be focussed on making their own stuff operate, rather than being good tech citizens in a wider eco system.

I'd like to see some report of when things were turned on, how much by (i.e. brightness of lights, temperature of thermostat, etc).
If I had visibility over the house then I could improve automation. And I'd understand the most likely trigger for the event.
