Any projects or products that can work with HA or ESPHome?
#Christmas Tree Train

Hi @raven heath, so I'm not trying to be an ass here, but the question is a bit broad.
It’s all too easy to fall into the trap of the XY problem. If you describe your goal first, then others can understand what you’re trying to achieve.
Do you have a train, do you need a train, is "train" a acronym?

Now that you ask is there a way to make this three-way switch electronic with some D1 WeMo?
upbeat field
Yes, most likely.
You just turn it on and use a wall-wort zigbee plug on the transformer
Or you take the engine apart and replace the switch with relays.

Was thinking the relay route that could be doable. Like zigbee can fit it coal car with battery, have the wires go to the switch
Not many relays can run with less than 12v though

Sonoff SV works on 5v.

ok, that in theory should work, but wondering about battery power/life
im starting to rethink this whole thing now, maybe using a switch-bot finger bot thingy could work. There would have to be some physical modification of the train, but it would work out of the box and battery lasts a year of those.....ahhhhh
