Good day.

Sorry for the delay.

Have you tested the Tapo P100 with other devices, like your smartphone, or lamps?

By the way, what do you mean switched power supply (12Vdc-5A) and can I have a specific model so that I could have a further check?

Thank you very much.

Hi Brook,

I tested the Tapo with a multimeter and didn't switch.  

With switched power supply I mean a 230Vac-12Vdc (5A) power supply, to lit led strips up.

Yesterday I received a new Tapo and I have tested with the same power supply and is working perfectly, so I asume that it was a defective unit.

Tapo plug is now working with my power supply.

I have exactly the same problem. Not at all impressed with TP-Link, this is the first smart plug I decided to buy and straight away it's a fail. It's all fabulously smart communicating with Google and Samsung and all but it fails to do the one thing it's been designed for - supply electricity. Tried different sockets and different appliances to no avail. Probably don't even have the receipt to return it because i didn't anticipate any issues so really annoyed.
