Plug won't turn power off #36

Open synthc opened 3 months ago

synthc commented 3 months ago

Communication with the plug seems to be working fine and I can turn it on and off both wirelessly and manually via the button (and the LED indicates the appropriate state); but the power is stuck on - it will never turn off the device that's plugged into it.

I've tried doing a full reset and re-adding it to the network and it worked for a little while before starting this behavior again. Now it won't work no matter what I do.

Can you hear the relay clicking? Pretty weird for it to work and suddenly not work. Sounds like a bad relay. E-mail me and I can send a replacement. brian@kaufha.com

Yes, I hear it clicking. I sent you an email, but your email server rejected it:

That's a pretty weird error. Email is working for me. Maybe try sending from a different email address or computer.

I tried again, the email didn't bounce this time.

The replacement is working. Thanks.

This issue is has now started occurring with the replacement plug. Exact same issue, I hear the relay click when I switch the plug on/off but it doesn't cut the power to what's plugged into it.

I have a single LED tube shop light plugged into it. The plug itself is plugged directly into an outlet (I had it on a power strip and moved it to the outlet, thinking maybe the strip was interfering somehow). The plug is the only thing plugged into this outlet.

I have three other PLF12's and all of them work just fine. Do you have any idea what might be going on here? If I turn the switch on/off repeatedly it eventually turns the light off.

What are the specs of the light that is plugged into it? Sounds like the symptoms you might expect if you were plugging in a large inductive load that created an inrush current and welded the relay open.
