I want to replace my existing upstairs/downstairs traditional on/off change-over wall switches (3-way switch) with pulse switches, not sure about the exact terminology. The Shelly Dimmer (v1) will be placed in the central ceiling box. I want to use existing wiring.

Option A would be to wire everything basically identically but use to the pulse based change-over wall switches (3-way pulse switch).

Option B would be to use some Wagos and use basic single pole pulse based wall switches (2-way pulse switch).

Is this correct?

What would be "best practice"? Option A or B?

Also I intend to use a Shelly dimmer for a three wall switches for a single light setup that is traditionally wired to use two 3-way switch and one 4-way switch in the middle. Option B seems to be the only way to achieve that using the existing wiring?

Any help would be appreciated

Follow up: Ordered another Shelly1 which came in today.

Installed it and the physical button switch is finally working as expected.

After tidying up the wires and configuring MQTT for integrating with home assistant, I am quite happy with the results

Thanks all

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.

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?
