I picked up a 5 v a couple months back because nothing else fit in that niche. Its a damn good phone. Only thing missing for me is a removable battery. I’d like a slightly smaller size overally but compared to everything else in the market, its small already.
If it was setup properly, you just us an if statement like, “if communication lost to control for t>5 seconds, release balast” or something like that. I had 0 issue with the controller being an ots consumer good. The rest was an idiotic design, I won’t even say it was engineered.
