Tasmota Shelly1 as 3 way switch

Hardware

Hello folks,

just tried to use a Shelly1 with Tasmota on board as 3way switch following this sketch with no fortune (the power went down):

I think that this scheme is working only with devices with the original firmware on board… Anyone can confirm?

Thanks a lot

Hi
This will also work with Tasmota Firmware if SwitchMode in Tasmota is set to 1

Have a look at the Tasmota Command Wiki, everything is well documented.
