I am not sure about forum etiquette, so apologies if i have posted in the wrong place but i thought it would probably be best to start a new thread for this.
I have purchased the Shelly 1L and Bypass for a 2 Way Switch, single light, setup and have fitted the bypass without issue. However, the wiring in both switches are as shown in the attached image and I have wired in the shelly 1L as suggested by Dimitar Dimitrov, and shown in the image below. Sadly though, at this stage all I can do is turn the light on/off via the shelly and the switch it shares a wall box with. If I then flick the other switch on/off it cuts power to the shelly and the switch in the wall box with the shelly.
Unfortunately i do not know the circuit is wired in the walls, all I know is what i have posted above and that, before installing the Shelly, both lights would alter the state the light was in when flicked - regardless of the current state of the other switch or the light itself.
Any help/insight here would be appreciated. All I can think of is that the light itself might be in between the two switches in the circuit and that putting a Shelly 1 in the ceiling with the light might work. However, I have the Shelly 1L already and would prefer to find a solution that utilises that if possible.
Thank you all in advance and i look forward to hearing your suggestions.
