Discussion Kasa smart bulbs don’t work in HB after firmware update 1.1.1
TP-Link / Kasa devices were recently discovered to have a vulnerability CVE-2026-76784, and they released a firmware update for several devices.
In my home setup I have 4 Kasa KL125 smart bulbs. Two of them seem to have self updated their firmware to 1.1.1 in the last two days and I can no longer control them from HimeBridge or HomeKit / Apple Home app.
I reset the two bulbs and re-joined them to my home network with the Kasa app and I can control them fine in the Kasa app, but they do not appear in homebridge or the home app.
I am running HomeBridge 2 with the HomeBridge TPlink Smarthome plugin v8.0.4, which does not even seem to be able to find these two bulbs on my network. My WiFi and router both show the bulbs on the network and they have been assigned valid IP addresses. Even entering these IP addresses as manual discovery they still do not show up as homebridge accessories, and do not appear in Apple Home app.
Not sure how to fix this at this point, the bulbs don’t seem to support rolling back the firmware (not that that would be a good idea anyway).
