Shelly 1 to control another shelly 1? (alien.top)

Hello everyone,

I have a question about shelly 1, didn't use it so far. Can I connect one shelly device, and depending if that shelly is currently getting some power then turn on/off another shelly?

First shelly will be connected to device, and if that device shares power through to shelly, then second shelly should turn on another device.

Is that possible with that? or should I use something else?

So, first of all, this solution will be cleaner and easier if you could power the first Shelly all the time and wire the switch into the switch input. But if that's not possible, you can still make it work.

If you can wire the Shelly for permanent power, I think you can even make it work with the original Shelly firmware. It can call webhooks so the first Shelly can call the HTTP API of the second Shelly. I didn't try it out though.

Otherwise you'll have to flash Tasmota: Original Shelly series Shelly Plus series

Then you can configure the first Shelly to periodically (e.g. every 55 seconds) call Tasmota's HTTP API on the second Shelly and use PulseTime on the second Shelly to turn off after 1 minute.
