Tapo P110 no longer works in home assistant - unsupported device

[pgit2345]

The problem

Over the last week or two, one of my two P110 smart plugs has stopped appearing in Home Assistant. It was showing an SSL type error when trying to reload it.

I have tried setting third party services to on (it was off). Tried toggling it on and off too. Tried re-loading the device in HA. Checked the tapo app was up to date. Tried upgrading Home Assistant OS. Tried updating the firmware on the plug. Tried factory resetting the plug and re-adding it to Tapo app.

Tried deleting the device from home assistant, now when trying to re add the device in Home Assistant I get:

Connection error: Unsupported device 192.168.1.114 of type SMART.TAPOPLUG with encrypt_scheme EncryptionScheme(is_support_https=False, encrypt_type='TPAP', http_port=80, lv=2)

Although it wasn't working on earlier versions too - upgraded all in an attempt to see if a fix was already available.

Mine was working this morning until I rebooted my HA server and now it refuses to connect.

Connection error: Unsupported device 10.0.0.100 of type SMART.TAPOPLUG with encrypt_scheme EncryptionScheme(is_support_https=False, encrypt_type='TPAP', http_port=80, lv=2)

Interestingly, it is only the P110 and none of my other Tapo/TP-Link devices are having the same issues.

Similar happened to me, not sure why but going back into the Tapo app and enabling 3rd party compatibility again made it work.

You'll find that here

Tapo App → Me → Third-Party Services → Third-Party Compatibility → On

[adamtiley]

I've managed to find a fix by going into the Tapo app on my phone (Android), clicking the "Me" tab at the bottom > Third Party Services > Enabling "Third Party Compatibility".

Once I enabled this, I reloaded the failed devices and they just worked again!

Oh you posted as I was typing! 😄

[pgit2345]

Unfortunately enabling third party services has not helped in my case.

[pgit2345]

Actually, scratch that, just gave it one more try.

It worked this time. Toggled it off. Saved. Toggled it on, saved.

Quicky went over to HA and re added the IP, it worked this time.

Not sure if it was a speed thing, if you have to do it quickly, or if something else has occured that made me lucky this time.

Fingers crossed the entity remains consistently available as it was a bit flaky before it completely failed to appear and the other P110 disappeared for a bit yesterday too.

I would imagine the plugs did a firmware update that enabled TPAP encryption, and this setting allows Home Assistant to be able to bypass this, so hopefully we won't see any re-occurrences of it (especially considering the platinum grading of the TP-Link integration itself)

Glad you've got it working now though!

Had 4 out of 10 P110 plugs refusing to connect to HA. Tried reloading each device, did nothing. Checked IPAddress all online and responding to ping. Tried reconfiguring a device and got 'Connection error: Unsupported device 192.168.1.114 of type SMART.TAPOPLUG with encrypt_scheme EncryptionScheme(is_support_https=False, encrypt_type='TPAP', http_port=80, lv=2)'. Went into Tapo App (had to login, since I don't use it) and checked 'Third-Party Compatibility' to find that it was already on. Went back to HA and all 4 devices had refreshed and re-connected! All 10 P110 devices are awaiting a firmware updated so not sure that its a firmware issue, maybe its was logging into the Tapo app that did it for me.

Anyways all working for me at the mo :-)

[pgit2345]

Actually that could be it.

I did clear the cache and cleared data and force stopped the tapo app, then logged back into it.

Maybe that was what got it working in the end, the next time I tried toggling 3rd party (after many attempts) then re-adding the plug to HA it worked.

[craigchambers]

I had to update the phone app before I could get this to work. App auto-update enabled on phone, but app was still out of date.
Once the app was updated and I checked the option, 3rd party compatibility worked.

Solved, you have to go to tapo app - >me-> third part services- enable. Apparently with firmware upgrade it automatically turn it off..

Tapo app, me, third part services-, enable.. now it works again

[adamtiley]

This can probably be closed now as we've already found the resolution.

[Wlanfr3ak]

TLDR: Tapo App -> Me -> Third Party Services: Disable, Save, Enable, Save... Now its run without problems.
