[TheMitch]

Same issue applies to the p115

[dye87]

I have also the issue with my p110's

[Kamil3001]

Hi, I am having the same issue with P110 but not all of them. 3/7 have this issue.

EDIT: I have managed to fix this by relinking the plugs with the Tapo app. Hold the power button for 10+ seconds and then re-add the device in the app. Then immediately add it to HA

[jnsw]

Having the same issue, stating "Failed to connect" but I managed to add 2 devices, sometimes mutilple tries help, but its really painful always to fill out the fields

someone into that issue? logs saying:

EDIT: issue resolved, just had to update my tapo plugin from hacs

[achie188]

I'm having the same issues - have reinstalled the tapo integration through HACs as well as readding devices in the Tapo app itself.

[NathanPeake]

installed did the setup was working fine for a few hrs restarted HA and now its not working as expected. just looping on the retry.

[alx-xlx]

I am having the same issue, the device had previously worked well. Now I have readded the device on the Tapo app with another name and then trying to add it to HA on the same previous IP address and I am unable to connect

I get this error, I have no idea what to do next

I got new Tapo P110s this week and none of them can be connected to by Home Assistant but I can ping them from Home Assistant.

[omega015]

Same here, new P110's home assistant (all latest versions) cannot connect. "Failed to connect" error.

[hwharwig]

Same here, 2.3.0. 1x P110 was working other 3 not yet connected. Now connected all 4 and updated firmware on all 4 to 1.3.0. All 4: "Failed to connect".

[Babacooll]

Same here with all P110 😞

[peruggini]

I don't know what happened, just gived a "desperated" try and one device was added successfully. Then the other two, ok with them, too! Is there something I can do to provide useful data?

[peruggini]

HomeAssistant restart and issue appeared again

[jc12col]

Same issue here "Failed to Connect" Although I will add that I have some tapo cameras, and having the same issue.......... searched high and low for answers on how to get these working again, but getting to the point where I may just go to a different brand, any suggestions?

EDIT - I am an absolute beginner with HA - so struggle with most things!

[whoisthedaddy]

Hi all, not sure if this is helpful and a bit of a ramble I'm afraid but I have 23 x P110 connected via the integration and they have been flawless so can't help thinking it may not be the integration but something else within the system? I did encounter problems when ticking the box 'track by MAC address (experimental) so I now leave this unchecked. I also assign static IPs to all my P110's. I also had some issues with the KASA and TAPO apps (still have a few HS100s) but it turned out they each had different email addresses associated with them and as soon as I changed this those issues disappeared. My process to add is to connect them via the Tapo app - they are all called 'Socket: xxxx' - then update the firmware (the last one I did last night after the integration update as it shows Hardware version 1, Firmware 1.3.0 Build 230905 Ref 152200. Take a note of the MAC/IP address and assign this as static on the router and then add into HA. I'm running HA on a RP4. I also have them alll on their own IOT network. Although the logs might suggest otherwise based on the above I can't help thinking there may be a conflict elsewhere - as an example I've had all sorts of problems recently with HA 'randomly' restarting and each log was different, I tried disabling integrations, add-ons etc but ultimately the problem was that the PSU for my PI wasn't sufficient - upgraded this and no random restarts anymore.

[jc12col]

Hi all, So, I still cannot get this to work and agree that it is probably not the integration.

I have just deleted all previous Tapo integrations on my HA. I have set up a new Tapo account on a different email, (all lowercase) in the app and added a P110 plug device - successful.

I have downloaded and installed from HACS again

• Started the process of adding a device
• Input the correct IP (have pinged and all ok)
• Correct user email
• Correct password
• Failed to connect.........

Does anyone have suggestions on what to do next?

[whoisthedaddy]

Hiya - that does seem strange - you can add one but no another would immediately suggest there is something one with the only thing that is different, i.e. the plug - perhaps the second one is faulty - reconfigure using the app and try again? (What did you call the first plug and is the second one of a similar name - perhaps it doesn't like the name you used in the setup? Firmware versions on the plug the same? Sorry nothing specific but a few things to try....

[stephencoe]

I was having the same issue with this after a recent update. One thing that stood out for me was the IP it was trying to connect with wasn't the IP of the device (I would use 192.168.68.115 yet the logs show 192.168.68.107).

It felt like it was cached somewhere, my suspicion was that something relating to mac addresses prior to the update.To verify the underlying code I ran a test with this and was able to connect successfully

I can't be certain which change was finally responsible but this was fixed for me through one of these changes:

• static IPs for the plugs
• remove all tapo devices
• remove the tapo controller in HACs altogether and re-download / install again
• Using a different browser (not the app) re-add the integration

Once I did this for a single plug the others were auto discovered and the integration is now operational again

[Rusketh]

Found out there was a capital letter In the email when I signed up, tappo does not show you the capital letter. Created a new account with out using any caps and it works fine now.

[jc12col]

Hey all, Going to give my Tapo one last try before moving on to maybe TUYA.

What's the best way to remove all previous Tapo integration and data so I am starting afresh?

I have a feeling that deleting the integration would not do this.....happy to be proved wrong.

Do I need to also Create a new Tapo account and register my plugs there?

Then, with a clean sheet, the best way to install 4 x P110 plugs?

Happy to follow suggestions to get the best outcome, ie Tapo integration working!

I am a beginner, so please feel free to write your comments as if I am an idiot, (maybe I am, as I cannot get the current integration to work!)in simple terms so that other beginners like me will also be able to benefit from your knowledge.

Appreciate anyone who takes the time to respond to this!

Thanks

I'm getting a similar issue that's described in this ticket. All my Tapo devices were working fine until a few days ago.

My username and password as all fine, I'm getting any errors with those.

It looks like others are having the same issue: https://community.home-assistant.io/t/tapo-devices-fail-to-connect/675178/8

I'm running the following if that helps:

• HA Hardware: Raspberry Pi 3 B+
• HA Core: 2024.5.5
• HA Supervisor: 2024.05.1
• HA Operating System: 12.3
• Tapo Control Integration: 3.1.2

The devices I'm trying to connect are:

• P100 plugs x4
• L530B blubs x2

Here is the latest error I get in my logs when trying to add a device:

This error originated from a custom integration.

Similar issue as @blackthorn87, 2 out of 4 P100 devices stopped working (I didn't notice this until today, so not sure when exactly). Tried downgrading & upgrading the plugin and removing and readding the devices, but gettimg the same tapo.errors.CannotConnect error.

What's interesting is that the 2 other plugs from the same package of 4 with the same firmware version work.

I figured out my issue, it was user error (https://github.com/petretiandrea/home-assistant-tapo-p100/issues/774).

I managed to get one of the non-functional P100s integrated back. Not sure which of these steps is significant:

1. Remove plug from HA
2. Downgrade Tapo plugin to some older version
3. Restart HA
4. Upgrade Tapo plugin back to 3.1.2
5. Restart HA again
6. Change account password
7. Update plug firmware
8. Dismiss the auto-discovered plug (I'd bet this is the significant one)
9. Add the switch manually
