@Craven unfortunately the "customer service" and "technical support" is very poor, which is surprising as it's a well established brand. 

I've had this happen to 3 of the 5 C320WS cameras (I bought a 6th as a spare to swap when one fails whilst I await them to exchange under warranty, which also takes longer than it should)

However, I have found the only thing that works is to factory reset the camera, which gets it working but it's random how long before the issue reocurrs

I had the same problem with spotlight turned on permanently last week following two short power cuts, and after support couldn't resolve the issue via chat, email (24hr wait between them) or beta firmware, took matters into my own hands and reset/removed and reinstalled the C320WS via the app (not reset button)

This fixed it (at least for now... doesn't inspire confidence)

  @robfol agree with you on that, had 3 of mine do the same but tp-link don't have a clue. one camera has done it multiple times but it's been going about a week so far without issue following the last reset

  @robfol 

Removing and reinstalling the camera from the APP (I am also using Tapo Beta app) worked as you said.

Thank you because I thought that I had to use the ladder to get up there and do a hard reset and as I said I really straggled to install it just because I am getting vertigo with heights. Luckily I am pretty handy and I could install it in less than a minute but still on just the thought that I had to go up there in the corner of my balcony....

Thank you guys again for the advice!

I have the exact issues with my CW320WS.l 2.0. The spotlight is always on and the proposed solution is not working for me. I also have the hotspot in my Wi-Fi list.

Firmware version 1.0.5 build 230316

  @energiya Have you tried to do the following steps?

1) Remove the camera from the application (not reset)

2) unplug the camera from the electrical outlet and plug it again after a few seconds

3) wait until the led on the camera starts flashing red and green successively

4) add the camera from the app and follow the instructions.

If you dont do the steps 2 and 3 you wont be able to add the camera back.

  @energiya are you guys still suffering the same problem?kindly share the solution...or any way to return this tapo device as it's of no use as it was intended for

  @ASB8687 factory reset from the app but you will have to put all the settings back in works. 

If you bought it from Amazon you should have some luck returning it, but if it was directly from TP-Link then judging by the "customer service" I received you'll have more luck getting blood out of a stone.

  @Wayne-TP this is the way. I  same problem and the only way to fix it was doing a hard factory reset.
