Shelly 1PM - 2 Way - Manual switches need to be toggled twice after app toggle

I just installed a Shelly 1PM in a two way switch configuration. It’s working great except for one thing and that is that I need to toggle the manual switches twice if I turned the lights on or off from within the app. I did not expect that, is that normal?

PS: I installed the Shelly in the light outlet and not behind one of the two switches to that I did not have to pull a neutral wire.

No, I don’t think it is normal. I don’t have a shelly1PM, but I have 10 shelly 1’s installed, and none behave like this.

I found the problem! I needed to put the Shelly in edge mode.

@TheNr1Guest:
Great, could you tell me please how to set the edge mode in HA? thx

@lj80driver
Sure, just go into your Shelly app, select a device and go to settings. Under button type you can select edge mode.

PS: You cannot do this from HA.

Great thanks! Totally forgot that there is such an app :rofl:, managed to do everything in H.A. so far…

@TheNr1Guest, I just got the Shelly 1pm https://www.amazon.com/gp/product/B07RN42JC7/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1, can you share the wiring diagram?
