Model: Tapo P115  
Hardware Version: V1
Firmware Version: 1.1.3 Build 240523 Ref 175054

I have a box of four of these devices. I have a dozen or more Kasa devices running on my HA.

 

I just pulled another P115 out of the box to plug in my compessor. It paired to the app just fine. It was found by Alexa just fine and is controllable by Alexa. I don't use the app at all except to pair up devices. 

 

This new P115 was detected by HA no problem, but won't authenticate. 

 

  • I reset the P115 and re-added it to the app. Same result, same IP address
  • I pinged the P115 from the LAN, it pinged fine
  • I restarted HA, same result
  • I verified my creds with KASA. They are correct. I keep them on 1Password, so not typos.
  • App and Alexa control the P115 device just fine
  • I have another P115 from the same box active on HA and it works fine.

 

Ideas?

  @JimS1954 

I'm having the same problem with 8 tapo cameras. They worked fine until about a week ago. Now HA wants this re-authentication. I can login to all of the tp-link/tapo accounts that I want, but the same login does not work for these HA requests from tp-link. Have you gotten any answers?

 

Thanks.

  @SteveF1950 

As of yesterday, TP-Link L2 Tech Support has said nothing more useful than to point out that Home Assistant is not officially supported by Tapo. I have a phone call scheduled for tomorrow, but they blew off the last appointment, so I'm expecting nothing more.

  @JimS1954 I gather they blew you off? This ticks me off because I missed the deadline to return them, so for me it's a waste of money and time.  My guess is that whoever wrote the integration has not updated for Tapo and Tapo has done nothing to address it, another promising brand out. I bought them for the energy monitoring feature.  

 

Another brand that works but does not really integrate is eWeLink, which a creates a separate work space that blows off HA areas and rooms.  Why bother? 

 

TpLink Kasa is the only brand that has been consistently reliable for me, including self recovery from power/network failures.

  @SamAtw Yeah, they blew me off. It is very disappointing, since TP-Link had been my go-to vendor for switches, etc. I did find a decent alternative for energy monitoring plugs. The Iotrero PG03. Seems to work quite reliably.
