Hi,
I saw another thread about similar issues to this but it's marked resolved without a solution so will try and raise again.
I have a Shelly 1L installed without a neutral and with an physical switch wired into SX and SW2. It powers a LED lamp (compromising 7 individual bulbs) which is wired in parallel with a bypass. when I power it up one of two things happen.... either it works for a bit then goes into fault mode if I switch it too often or just starts up in the fault mode.
When in the fault mode the bulbs are dim and flicker a bit and it drops off the WiFi. Sometimes I can get it to work by switching the switch and sometimes it stays like that no matter what until I switch off the breaker.
Does anyone know how the bypass it's supposed to work exactly? I've tried other (inferior) switches before also with limited success that just just use a 400V 1uF cap as the bypass.
Has anyone had anything like this and got to the bottom of it? I'm tired of messing with it 
The load when fully on could well be more than 20W so maybe the bypass is doing nothing then when it tries to turn off the lamp suddenly passes no current and the bypass doesn't kick in quick enough and the 1L loses power.
It's wired like this except SW1 is not connected: https://shelly.cloud/wp-content/upl…tral_wiring.jpg
Ideas anyone?
Thanks,
Peter.
