Hi everyone,
I’ve just set up a fresh installation of OpenHAB 4.1.3 on a Raspberry Pi and I’m trying to integrate a Tapocontrol device. However, I’m encountering a communication error:
COMMUNICATION_ERROR
invalid http-response (9001)
Builded the snapshot solved the error:
git clone https://github.com/openhab/openhab-addons
mvn clean package -DskipTests -pl :org.openhab.binding.tapocontrol -am
Hi,
facing the same issue. Just updated my docker container from 3.4 to 4.1.3 to overcome the communication issue that was introduced by a new Tapo firmware just to run into this issue.
I already tried to uninstall / reinstall the binding (incl. reboot of the container in between) without any improvement.
Unfortunately I’m not sure if your solution on a Raspberry Pi would also help with that issue on a docker container and what I would need to do exactly.
Any hint would be appreciated.
Thanks.
Hello,
you just need to manually install the jar of the tapocontrol on the snapshot release
Thank you so much for the prompt reply. Awesome.
Ok I guess I got what I need to do.
-
Setup a box that has maven installed (e.g. on my PC)
-
Clone the latest version of the add-ons repo (GitHub - openhab/openhab-addons: Add-ons for openHAB) as this one contains a fix
-
Use maven with the cloned repo to build a jar
-
Uninstall the current binding and reboot the container
-
Copy the jar to the add-ons folder for the container and reboot the container
Does this sound correct?
Yes you can download maven 3.9.2
Then git clone
Go inside the project of the tapo control (sorry Im from phone)
mvn clean package -pl -am

Hello all,
could you maybe explain why this should be necessary and what changes when rebuilding the same sources?
I am facing the same issue.
When executing the mvn command i get an error:
[ERROR] Could not find the selected project in the reactor: :org.openhab.binding.tapocontrol
Any thoughts on what Im doing wrong?
Complete newbie by the way so keep any replies simple please! Although I did work out how to download and run maven 
Thanks

Hi, I have now with 5.02 the same problem with my P100, do you have an idea? (was fully functional some weeks ago..), two devices and same problem.
I have the same issue with P100 and P110 Plugs.
3 of 12 plugs stopped working the last 2 days.
The problem seems to be related to new Software 1.4.0 deployed some days ago on 3 devices.
The plugs running with the previous SW 1.3.4 are all working fine with the binding.
All plugs updated automatically the last 2 days are stopped working with the error 9001.
I disabled the automatic update on all of my remaining TAPO devices.
Hi, I have the same problem since today on a P110. Yesterday everything was working fine with the unchanged Version openHAB 5.0.2
I just found the solution - with a hint in another thread.
You have to enable the 3rd Party Option in the original TAPO App.
I enable the new option and all plugs became ONLINE again

I can confirm this is the Solution. Many Thanks!
I can also confirm, that this Issue was introduced with the Firmware Version 1.4.0 of the P110

Hi,
for me it is not a stable solution. The state of the plug (P110) switches back and forth between green and red.
Can anyone confirm that he also sees this behaviour? This leads to a behaviour where sometimes the command (switch on) is not executed, whiile a second later it works.
Someone pointed out that this behaviour is triggered while the TAPO App is in use. I cannot confirm this.
Furthermore I wanted to ask whether anyone has resolved this problem on openhab 5.0.2. If so how?
Exactly! It is the item at the bottom “Compatibility with 3rd party vendors” in the Tapo App with the title “services from 3rd party vendors”. You need to enable only this. Then my 2 P110 plugs responded immediately. (I hope my translation is correct) Thanks!
I can agree, I have enabled third party in the Tapo App. The P110 power outlet is switching between online and after a some minutes to offline. Then online again and so on. It’s a new P110 Plug with firmware 1.4.0
I can’t observe this with an older power outlet running firmware 1.3.1; it seems to work there.

I also have 1.4.x Firmware. How do you run openHab? Docker? Could it be that you have recently upgraded to openHab 5.x?
I‘m experiencing exactly the same issue. Any idea on how it can be solved?
As someone mentioned above - for me it was the new Tapo security settings recently introduced into the Tapo app. You need to allow 3rd party services in the Tapo app….
