Latest #homeassistant update (2026.3.4) breaks the super useful tplink_deco custom integration: connected devices are listed, but all have a status of "unavailable" and no further data. Logs show lots of 500 errors querying the AP.
Rolled it back to 2026.3.3 and it's all working again.
Unfortunately the tplink_deco integration is unmaintained, so I hope this can be fixed somehow 😕
I started a thread on the #homeassistant forums for the problems with the #tplink #deco #hacs integration:
https://community.home-assistant.io/t/tp-link-deco-integration-broken-on-2026-3-4/998749/1
And opened a Github issue:

I upgraded HA to 2026.3.4 recently and the TP-Link Deco integration broke. It appears to still connect to to the main Deco (I have 3x M5), find the other units, and gets a list of connected clients, but no further data and the client statuses are all listed as “Unavailable”. I tried deleting and reinstalling the integration, restarting HA, etc., with no change in behaviour. Looking at the logs in HA there are a lot of 500 API errors relating to it. Rolling back my docker container to 2026.3.3...
This seems to have been the underlying issue, fwiw:
