Flickering LED bulbs with bypass Shelly 1L

    • Autor

    There has been lot of problems with flickering led bulbs when Shelly 1L has been used with bypass. Quite many users have same issues as seen here Shelly 1L flickering LED bulbs

    In my case I'm using Shelly 1L to control two led bulb (Airam GU10 4,5W) and I got bypass installed. When the switch is turned on, no problems but when the switch is turned off, there is visible pale flickering from the bulbs. Bypass should solve this issue, but in my case it doesn't. If the bulbs are the issue, please guide me to the right direction to what bulb are known to work in this scenario, thanks

    I did some trouble shooting today and replaced the 2 x 4,5W bulbs with 2 x 10W led bulbs and removed the bypass (since the power is now 20W total). The flickering stopped when switch is off, but now the led bulbs are slightly illuminated - enough to see in daylight. Then I added the bypass and system is now operating as expected. So it took total of 40W to fix the issue. Weird.

    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(

    Amamdouh it won't help you if you repeat this text 5 times in other topics

    But try to answer your question: not every light bulb behaves the same way. 100% compatibility cannot be guaranteed. In this case it only helps to change the type of light bulb or to connect the 1L directly to neutral.

    My Shelly Bypasses are literally not working, with any of my lights. I also have a lamp with 4 7,4w bulbs and still flickering.

    Then tried with 2 outdoor lamps of 30watts and still always on and flickering.

    Any idea?
