Shelly1 physical button switch not working

vave

Hi,

I've installed a shelly1 for a (230V) light exactly as depicted here using a single physical switch: https://shelly-forum.com/index.php?atta…usschaltung-png. Updated to firmware 20190821-094851/v1.5.2@4148d2b7.

Configured shelly1 as edge switch, but it the light is not turning on/off using the physical switch. The internal web page on/off switch works fine.

I've measured (using a digital voltmeter) the AC voltage on the [SW] terminal and confirmed it receives 230V when I flip the physical switch. In the off position there is a small residual voltage of about 35V which seems to be "phantom voltage" or inductance from other nearby wires.

I've already tried a factory reset, but nothing I have tried is working. Could it be the "phantom voltage" or is there some options for me to try?

Hi and good morning vave , welcome to the forum.

Have you tried, to configure it as "Toggle-Switch"?

Wether this is the cause, you can check:

disconnect the SW-line
connect "L" of Shelly with a switch to "SW"

Function ok?

Good Luck.

Thanks for your suggestions. Tried toggle switch mode, but that does not work either

I've configured another switch directly between [L] and [SW] inputs, but no change in either edge or toggle switch mode. FWIW: that "phantom voltage" I mentioned was now only about 4V, so definitely a red herring.

Unless anyone has other suggestions, I'll try to get the Shelly1 RMA'd.

I think, that's the right way.

I had 2 Shelly 2.5 where one SW terminal on each had a contact problem. Therefore the physical switches did not work properly. Alterco replaced them quickly and without fuss. So, they are aware that such things happen and react accordingly.
