Fibaro wall Plug, off but still giving/leaking power?

Hi
I’ve been using Fibaro wall plugs for a while now and never had any real issue with it. However last week I noticed that the the led on my coffee machine was glowing very dim, but still. So I unplugged it and the dim light dissappeared and re appeared when I plugged in it back in. If I turn it on the machine actually starts heating.
This "electricity leaking’ is actually new to me, I’m quite sure it didn’t happen before. Anyone else has this? Tips or tricks? Reset it maybe?
Cheers

Don’t think that homey has anything to do with that :wink:
