I once did that with a Samsung powerbank I have. Daisy chained the powerbank to charge itself and a phone in sequence.

The only thing that failed afterwards was one of the cables, but suffering a loss was definitely the reason I didn’t attempt to do that again.

Well, I did mention the Hue bridge so I’ve got Zigbee around the house (as well as some other Tuya wifi devices).

I’m currently in the process of converting to an additive setup so my wife and I don’t need a smartphone to do smart home stuff. I think I can work with the info, thanks a lot.

I’ve come across Shelly relays as well, they seem like a viable option to me. I’d probably prefer a separated network like Zigbee, but that should be doable. Thanks!
