[Bloating]

When I built my house years ago (well before Thread/Matter), I went through the dog & pony show with the local lutron, creston, vantage dealers. There are a few others around also, like centralite and loxone. It always came down to 1) I didn't want to be beholden to a dealer to change the timing on a light 2) those systems (other than loxone) were/are antiqued.

Ended-up building a PLC based system. Its been rock solid reliable & I can do pretty much anything I can imagine with it. Its a little risky, in that if I ever need to sell I've limited potentional buyers. But, I think thats the case with just about any centralized system. Not long after I looked at a lutron system, the local lutron tech passed away. One house under construction using lutron was brought to a dead standstill. AFAIK, there are no nearby lutron programmers to this day.

However, PLCs are easy to obtain, relatively easy to learn (if you're technical) and just about any small+ city is likely to have control engineers that might be willing to support as a side hussle.
