Tapo P110 shows cant create handshake (1100)

Setup, Configuration and Use Beginners

Hi! I am using openHAB 4.2 and a couple of Tapo device (plugs and lighs). Since a couple of days openHAB can not connect to the P110 plugs, I receive the following message:

COMMUNICATION_ERROR
cant create handshake (1100)

The events log show this messages:

2024-07-24 10:20:32.059 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing ‘tapocontrol:P110:de2c94f5cb:5C628B86F980’ changed from OFFLINE (COMMUNICATION_ERROR): cant create handshake (1100) to UNKNOWN
2024-07-24 10:20:34.068 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing ‘tapocontrol:P110:de2c94f5cb:5C628B86F980’ changed from UNKNOWN to OFFLINE (COMMUNICATION_ERROR): cant create handshake (1100)

Any ideas?

Have you tried setting Things to use KLAP protocol?

Yes.

I have the same issue here, also with a P110, Firmware Version 1.3.1 Build 240621 Rel.162048 and TapoControl Binding 4.2.1 and the KLAP protocol activated in the advanced settings…

Did you happen to resolve this? I am getting this issue too :sweat_smile:.

  • Model: P100
  • FirmwareVersion: 1.2.5 Build 240411 Rel.143808
  • Protocol: KLAP
  • openHAB: 4.2.2

No, I still have the same issue…

Any solution yet? I am in the same boat.

I had to swap one P115 with a spare one that was sitting in my drawer, because the old one had its relay contacts welded.

I had the same error after the swap but after update of the Tapo firmware everything works.

Hi :slight_smile:
Found a solution which fixed it for me. Keyword is “TP-Link Simple Setup”. I was very frustrated because I had the latest versions of all of it: P110M devices as well as OH 4.3.3 but I always got the handshake error with the second devices. Actually, the first added device of TP-Link was helping the second device and that was the problem. Removed every TP-Link / tapo device, added each device separately through the app and handshake worked.
