@Wayne-TP the smart plug is comnected to home office setup so I think load is not the issue here. Will try contacting the local support.

Thanks!

I have the same problem and mine was used to control a 45W phone charger - the support document says anything over 75W.  Has the P100 degraded even at that wattage?

  @AJ_ this is a very common problem. Many many p100 units are failing because the contacts are sticking. You can temporarily fix it by tapping the plug unit, whilst it's unplugged, to dislodge the contacts. But my solution has been to throw the unit out because it is unreliable and you shouldn't be tapping electrical contacts to free them up. Check the warranty and get it replaced if you can, or just bin it.

  @Blert I have had this a number of times, what solution I have found that has worked is to delete it from the app, then add it again.  Done this a dozen of times, and it worked every time.  The problem only happen to the one in the same as the router, all the others work OK, even if I fit a new one in it's place, it happens.  Only think it is due to been so close to the router and it throws a wobbly every to often.  It happened again today, so done as I said above and it's back working. Good luck.
