Shelly 1L without neutral and flickering LED bulbs

    • Autor

    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.

    I am facing similar problem, using shelly 1L with a line of two 23w Bulbs. I tried without bypass at first and in off condition the bulbs are not completely off and also little flickering. I added one bypass one bulb was off completely and the other still behaving the same(not completely off and also little flickering) after searching I found that some people solved the problem using 2 bypass so I installed 2 bypass one on each bulb. still I have the same one bulb was off completely and the other still behaving the same(not completely off and also little flickering). did you find any solution for that issue. i can see many threads for the same issue however no solution for long time. why shelly developers didn't take this seriously! what is the use of Shelly 1L if it keeps behaving like that! :( :( X( X(

    Same issue here, but I was able to resolve it! The Shelly bypass was having no effect on multiple (8) tested LED globes, 9W - 24W, $5-$13 AUD. All the LED globes had the same flickering outcome, some wiping the Shelly's configuration. I then realized that I had the bypass wired improperly, and instead of running parallel to the globe(load), I had it running between the globe and the neutral wire which just passed the neutral wire electricity. In the end, with the bypass installed correctly, I'm now not able to find an LED globe that doesn't work, testing the same batch as before. Hopefully this image will help someone else.

    I also got it to work using a 43W OSRAM Classic Halogen bulb, without the Shelly Bypass, but those Halogen Bulbs run so hot!

    What would be really helpful is if Shelly could provide a list of the makes and models of the globes/bulbs they used for successfully testing neutral-less Shelly implementations. I know that in this case, it was my own damn fault, but having a "known working" list of globes would have moved my troubleshooting efforts to the real problem instead of taking my frustrations out on the Shelly Support Forum. ;)
