Funny..I try telling this to people all the time. I usually get shunned. I received a free Prime membership a while ago and probably by a few hundred a month online on average. Ironically the smart wall outlets were the closest thing to being the 'cheaper' on Amazon. But buying a 5 pack from Jet ended up being quite a bit cheaper. They thrive on pure laziness of the consumer...which is killing it for them. Ie: the link above for the Etekcity switch 5 pack...was found at $24.99 (With no tax) and free shipping in like 30 seconds.
There's a reason Jeff Bezos is darn near the richest man in the world. Somehow he gets people to pay a membership fee..to over pay for stuff.
To answer your main question. For my pins I'm using a Veredge controller with smart wall outlets. This setup can get expensive as the wall outlets (one per machines) are about $35 a piece. I only have half my pins set up on this now. You can also setup scenes that are pretty cool.
For example When I hit 'Play Pinball' on my phone. All the track lighting turns on at 100%...then the first 4 games turn on. 5 seconds later the next 4 games turn on. 5 seconds after that the next 4 games turn on. 10 seconds later the track lighting gets dimmed to 10%.
You can set up scene however ya want. You could very well do another scene called 'Play Pinball Now' that turns everything on..and set the lighting at 10%
I have a scene called 'Play turds' ..and all the Stern turn on =)
I'm still waiting on a smart 20A standard wall switch for my arcade games..I would need 4. There was a company that made them a while ago... and stopped making them. There's a ton of choices for 15A stuff. You can get a 20a relay switch that fits in a standard wall switch box. But there is no manual way to turn the games on which would suck in case of a communication failure.
Which reminds me.. I haven't checked in a while for a 20A smart wall switch
