Shelly 1L no-neutral+bypass crashes on switching light

Aged#Mud#21623

HI

I just received my Shelly 1L and started to test it on ceiling lamp.

Cabling following the "no-neutral" diagram and using the bypass. There is only 1 switch (configured as edge), 2nd switch is configured as detached.

The lamp is a 13W "corn-style" led lamp with 86 leds format 5050.
Shelly 1L is configured on my Wifi with static IP, MQTT.

Everything is fine except that randomly, when switching it either on or off, the Shelly seems to crash.
It become unresponsive to IP (web, ping, mqtt, ...) and the lamp flickers very quickly at reduced brightness.
However the relay isn't clicking (perfectly silent).

If I unscrew the lamp (E27 socket), Shelly restarts.

Any idea on what could be the problem or a way to debug this ?

Thanks

I have the same issue using a Shelly 1L with bypass, with a test install. For me the unit crashes during a switch for both a physical switch as well as using the app.

I was using the switched circuit using S1 and Sx to the physical switches. I have rewired using RE: Shelly 1L: how to wire with 2 switches to used the switch live to the physical switches and this appear to be working without issue for a number of hours.

Update: Been working for a number of days without any issues.

Same issue: switching Shelly 1L off, it seems to crash and the lamp flickers very quickly (the relay isn't clicking).

I can't get the daroca's solution. Some one can explain me how to rewire?

Could you explain me how to solve it, please?

Thanks a lot!
