Intermittent failure of a smart plug to switch itself off

OwlPaste

One of the plugs I got managed to get into a state where it sometimes does not physically switch itself off, not quiet sure what causes it.

Happens using its own web interface or via the physical button or via home assistant
Web interface will then appear as off, however the devices remain powered
Also no physical click is heard when the switch off happens in this state, however enabling the plug will generate the click
Sometimes it gets out of this state and manages to power devices off normally, but eventually it gets into this strange state
I have 4 other plugs that do not have this problem at all

Are there known occurrences of this?

FW 15.0.1, recently upgraded to this fw, I cannot say for 100%, but I think it did not happen before this issue? But not certain.

Hi @OwlPaste

Thanks for stopping by. I’m sorry to read one of your smart plugs is misbehaving.

It is odd that it only fails intermittently. We are aware that a small number of the relays in our plugs fail prematurely. However, when this happens, the relay never switches.

You could try flashing an older build of the firmware? Instructions for doing so will depend on whether you have the ESPHome or Tasmota variant.

But if that doesn’t work, I imagine you have a relay failure, just not a typical one! If that’s the case, please contact me directly with your order number and the plug’s batch code. Please email: help@mylocalbytes.com
