HS110(UK) v4.1 beta firmware times out with the HomeKit probe in 0.11.0.1 #1788
Description
Three of my HS110(UK) plugs stopped working in Home Assistant after updating to 2026.10.1. I can reproduce it outside Home Assistant with python-kasa.
All three are hardware 4.1, running 1.1.1 Build 201203 Rel.135822. This is the old TP-Link compatibility beta that restored the local API (I think my plugs may be locked on this old compatibility firmware and can't be changed).
Testing the same plugs from the same machine:
- python-kasa 0.10.2: discovery and updates work.
- python-kasa 0.11.0.1: discovery succeeds, but updates time out.
- 0.11.0.1 with Module.IotHomeKit removed during module initialization: updates work on all three, including a second update.
A fourth HS110(UK), hardware 2.1 on 1.5.10 Build 191125 Rel.094314, works with the unmodified 0.11.0.1.
To reproduce:
import asyncio
from kasa import Discover
async def main():
device = await Discover.discover_single("PLUG_IP")
try:
await device.update()
finally:
await device.disconnect()
asyncio.run(main())The update fails with:
Timeout after 5 seconds sending request to the device PLUG_IP:9999
Direct system.get_sysinfo requests still work. Debug logging shows that the update now includes smartlife.iot.homekit.setup_info_get, added in #1566. Skipping that module fixes the timeout. Third-Party Compatibility is also enabled in the Kasa app.
Could the HomeKit probe be skipped for these devices, or handled so it doesn't prevent the rest of the update?

Do these devices support HomeKit natively or not? Sorry, not sure. If they do, can you get a fixture for them with the latest python-kasa? Trying to figure out why they timeout with the query. Thanks!

@ZeliardM no my HS110(UK) do not support HomeKit natively.

@AlecRust ok, thanks. My older HS300 and KP115 don't either and my EP25 do. Those are the devices I tested this on originally. I will go back and do some further investigation on the polling and answers and how it's actually handled. Thanks!

@AlecRust So it seems to be an issue with the older firmware as others who have reported this with the same plug I have but older firmware get the errors but I don't on the newer firmware. So it stands to reason that something in the older firmware has something to do with the ordering of the calls or calling items that are not supported right after system calls. We can re-order the calls but I don't think that removing it completely is the right call. Can you test by putting the HomeKit call later in the list instead of right after the system call? See if it still works after you reorder them? Let me know.

@ZeliardM yes, moving IotHomeKit to the end of the module order fixes it!
Also to be clear, I've confirmed with TP-Link that although I was on some old beta firmware for HA support, there is no new firmware available for these plugs.

Cross-linking, since this thread and #1791 haven't met yet: #1791 tracks the same regression with a protocol-level repro (#1803 was closed as its duplicate today). #1792 is an open fix that sends the HomeKit query in its own request instead of batching it.
On the reorder-vs-separate question above, here's the evidence from all the threads:
#1792 (ee5061e) has been run on real hardware: EP10 hw 1.0 / fw 1.0.2 (two people, one of them inside HA), HS103 hw 5.0 / fw 1.0.3 (9 plugs across two people), and KP115 hw 1.0 / fw 1.0.7. It hasn't been run on this issue's HS110(UK) hw 4.1 / fw 1.1.1 yet. @AlecRust or @igiannakas, could one of you try ee5061e on those plugs? That's the one gap #1791 calls out.
More reports of the same thing: #1799 (KP100 hw 3.0), #1803 (HS200 hw 5.0), and downstream home-assistant/core#185971, home-assistant/core#185900 and home-assistant/core#185859. HA 2026.10.2 (released yesterday) still pins 0.11.0.1, so affected HA users stay broken until a python-kasa release lands in HA.

@psiberfunk tested #1792 on all three of my HS110(UK) plugs and it works, including after reconnecting. Energy readings work too. Thanks!
