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 ?
