Device Tracker on TPLink not working

Configuration
1

I just set up a new instance of home assistant V49.0 on Hassbian. The device_tracker had been working for me previously on the V43.0 using all-in-one installation.

Here is the log:

I had used an encrypted password before with no problem. I also tried using an unencrypted password.

Configuration.yaml

device_tracker:

  • platform: tplink
    host: 192.168.1.1
    username: admin
    password:
    interval_seconds: 12
    consider_home: 240
    track_new_devices: yes

Any ideas?

I replaced tplink.py file from V49.0 with the one from V43.0 and it is now working as expected. Perhaps a bug was introduced at some point?

Hi,
I have the same problem with V50 too.
How to get tplink.py from V.43.0?
Regards

I had issues to get the tplink TL-WR841N up and running with device_tracker tplink.

After a FW update even a custom script wouldn’t work with their way of integration.
I read that tplink seems to have different mechanisms for different models - device_tracker tplink seems broken for a lot of models (just my impression).

Easy way to fix that for me: Flashed openwrt on my TPLink (took 5min via WebIF + reconfig of WIFI) - works like a charm with device_tracker luci.

NICE!!

Yes,
It is a solution.

The code for using a tplink router as a device tracker has been removed from Home Assistant. However if you are still interested in using that functionality, I have moved the code into a custom component here.
