Hey Guys, sorry if its been asked before.
Shelly 1 mini gen4, i have successfully wired in single switches and all them work.
On a 2 way switch not as much luck.
I have got to the stage where i can control the light via the shelly device but if i use either of the switches they dont do anything.
What i have found:
Measured the voltage between sw and neutral on the shelly device in both states of the physical switchs.
State 1 = 240v
State 2 = 150v
Ive checked my wiring multiple times and i have no shorts. But clearly the reason it doesnt pick up the state change is due to the voltage.
I have tried setting as a edge switch with no success.
All neutal and live feed i have at the light feed switch.
Does anyone have any ideas as to how to rectify?

Just wire one into the light fitting, and forget trying to wire one into each switch.

Yes. Call an electrician to wire it correctly.

In order for us to help you it might be worth to provide two types of information:
In which country are you located?
What does your wiring diagramm look like?
If you are located in Europe this is what your wiring should look like:
thankyou, i think thats where i went wrong, i ended up parralelling the light feed which obviously was causing me to power the lights full time unless i turned off via app.
thankyou so much for that diagram, it clears it up for someone whos had little sleep.
FPro, is the wiring diagram for a Shelly 1 Mini Gen4 to use with a 3-way/ SPDT (single pole, double throw) switch in the US the same as the one you posted for Europe?
