Are you referring to the audible click the paddle makes when you press it? Or are you referring to the sound of the relay that sounds more like it’s coming from within the switch?
If you could take a video, that would be super helpful actually.
When the LED bar flashes cyan and yellow, it typically means it’s resetting itself. Can you let me know the answers to these questions so I can better help?
What load are you controlling (ie: LED Bulb(s))
Do you have a neutral wire installation or non-neutral?
Is this a single-pole (ie: one switch to your load) or multi-way (2+ switches to your load)?
If it is a multi-way setup, can you let me know if you are using an auxiliary switch or a dumb/existing switch?
One random thing it could also be is that maybe the wires in the back are not secured tightly. It’s rare, but I’ve seen this happen too.
Can you let me know what hub you’re using (ie: SmartThings, Hubitat, Home Assistant, etc)?
Basically, there is a parameter that has the ability to turn on/off this click. If you’d prefer it to be on, there is a parameter called, “Disable Relay “Click” Sound” (or something like that). It’s Parameter 261.
0 = Sound is on
1 = Sound is off
I can help you more specifically once I know the hub you’re using.
Really weird I was going to suggest that, but I’ve only experienced it on the Blue Series and it does something different (it just goes into a boot-loop and clicks right away rather than when it is pressed – like you can’t even control it).
Good to know this is the behavior on the switch when line/load is swapped.
Ahh, nice – this didn’t even cross my mind, but makes complete sense. In the non-neutral setup, the On/Off is simulated and it doesn’t use the relay (which makes the clicking sound) but rather uses the MOSFET.
So, if the neutral wire popped out, that would for sure cause it. I would’ve never guessed that, so nice detective work!
