Adding Tapo P115 fails with Server response doesn't match our challenge #133164

p4cketw0lf · 2024-12-13T17:12:43Z

The problem

Receiving an error when attempting to add P115 Plug. I have other models working fine.

Invalid authentication: Server response doesn't match our challenge on ip

This issue has the same error as #132526 which was opened for cameras.

Using known good cloud auth username/password
Have enabled the new button in the tapo app settings > tapo lab > third party compatibility (this is a new setting but did not work before setting was introduced either).

Could you post more logs including the earlier log message which includes DISCOVERY.

dhilltx · 2024-12-13T20:22:27Z

I'm receiving the same error message when trying to setup a new P115 plug using the updated Tapo app with third party compatibility enabled.

I have multiple working TP-Link Kasa plugs but this is my first TP-Link Tapo plug.

Everything works in both Kasa and Tapo apps for iPhone.

I can sucessfully add Tapo cameras (C120 & C325WB) in HA via the TP-Link Smart Home integration, but none of the new P115s will work even thou they are detected (have also tried to add them manually via IP).

When I connected the new P115 plugs to my Tapo app via bluetooth on my iPhone it did successfully complete a firmware upgrade process, current version is 1.1.3 Build 240523 Rel.175054

Digging through the logs in HA there is nothing else with the IP nor DISCOVERY. Do I need to enable some other debug?

My previous understanding was that you should be seeing those as long as the debug mode was enabled on the integration page (and that you had restarted homeassistant after turning it on), but if not, you can modify your homeassistant logger configuration to include kasa and homeassistant.components.tplink with the debug log level to force logging from the startup.

This is all I'm seeing now after enabling debug and restarting HA

How did you provision the device? It says tss but I’m not sure what that means. The most standard is for it to say tplink

p4cketw0lf · 2024-12-14T00:19:47Z

Its being discovered. I also tried doing directly with add device and then entering IP address. Results the same.

Same issue on #113137 but no clear resolution on that. I did try rebooting the device by pulling power and that did not help.

crag364 · 2024-12-16T00:24:58Z

I had a similar issue with one of my smart plugs. Try removing it from the Tapo app and then completing an hard reset by holding the power button on it for 10 seconds until it blinks a green flashing light. Once it has done this, re-add it to tapo app and then try adding it to HA again. I think on my plug it hadn't synced the username/password correctly and doing the hard reset seemed to resolve this.

I just did this on 1 of 3 new plugs and it fixed my problem, same prompt for username & password but it worked this time, thanks for the 101 suggestion!

p4cketw0lf · 2024-12-16T01:32:45Z

Odd, its not working for me. It never blinked green only blue? Remove from app, it resets on its own. Hold down for 10 seconds and it blinks blue fast then goes to orange/blue. Re-set up in app, same error in home assistant after. It fails so fast its almost like its not even trying to hit Tapo cloud auth before it fails.

crag364 · 2024-12-16T01:41:20Z

Looks like blue is correct for the p115: https://www.tapo.com/uk/faq/30/ mine was the p100.

My experiences were different, but all sucessful. I do not have the Matter (BETA) installed but still have the Third-Party Compatibility On in the Tapo app, I haven't tried turning it off yet).

Plug 1 = I removed from Tapo app, held the button for 10 secs and it powered up my device (e.g. reset to on). It popped up in my app to add, but I ignored and setup manually via Bluetooth instead. During setup it detected a previous configuration and asked if I wanted to reuse or discard. I chose discard and completed setup normally. When I returnned to Home Assistant I had to enter email address and password (not username) and it worked!

Plug 2 = Similar process but never mentioned previous config or disgard, and honestly I didn't notice any green lights, just blue & orange under my finger. When I returnned to Home Assistant I had to enter email address and password (not username) and it worked! I just clicked add on the detected things, not via Integration or IP like others have suggested.

Plug 3 = Similar process, but this time no discard option either and I wasn't prompted for username & password in Home Assistant. This time I just clicked add and it asked me to confirm the area.

I'm good to go!

Are these 115s or another model?

p4cketw0lf · 2024-12-16T02:09:19Z

Ok so I got 1 working using the methods that @dhilltx pointed out!

Remove from App
Reset plug
In app, add new device manually by model number and setup as normal. There was nothing about previous config.

Here is the interesting thing. When setting these up in the app. When it discovers them on its own, it shows an image of a European style plug either P105A or TP10 NOT the P115. I think that perhaps its discovering them as a wrong device in Tapo app and apply some sort of other config?! Possible GDPR protection maybe or something? When telling it the specific model its the correct image during setup. That's the only thing I can think of.

I can confirm I saw a foreign recepticle icon in the app auto detection also, glad you are up and running!

dcb200270 · 2024-12-17T06:35:21Z

Same issue except with a bunch of P100's. This fix worked perfectly as described above.

Remove from App
Turn plug off and on
Add device manually via Tapo App

Home Assistant then allowed plugs to join with no user/password errors.
