Thanks Baldhor. I’ll look into this.
New test version available : ESPhome | Homey
The fix is proposed by TDonselaar (Tim Donselaar) · GitHub , thank you for your pull request!
It should fix the device reconnection issue based on Tim tests!
I cannot test this version (I don’t have a Homey running anymore). I will publish it to live only if I get several positive feedbacks!

I installed it and it works well so far. I’m going to do some more testing with it. Thank you for doing this!
I published latest version to live. Within 2 weeks, only 9 users used it, and there was no crash at all. Seems more stable than previous version.
Hi @Baldhor, thanks so much for all the work you’ve put into this app!
At IFA I spoke with the Open Home Foundation team about the ESPHome integration you’ve built, and we’re all very interested in working together to make this an officially supported app.
Since it looks like you might not be actively using Homey anymore, would you be open to discussing a possible transfer of the app, either to us at Athom or to the Open Home Foundation, depending on the path we choose?
If you’re open to it, feel free to reach out to me at partners@athom.com

The experimental version works for several Apollo devices. I’m using this version for the R-Pro-1 mmWave radar works well. I beleive PLT-1 and Air-1, MR2 mmWave are supported in the experimental version.
Hi @Baldhor . Thanks for this great app!
Im currently learning esp/arduino and ive downloaded your app. Ive had lots of problems connecting but now i think i found the problem, i think maybe your app needs to be updated to support the latest esphome firmware. It worked for me when i downgraded.
Ive used gemini ai to install and learn everything but im pretty sure that the firmware was the issue. This is a more detailed message gemini made:
Issue: The Homey app (manual add) fails to connect to devices running recent ESPHome firmware.
Details:
-
A device running ESPHome v2025.10.3 (compiled via the
esphome/esphome:latestDocker image) was online. It was confirmed working (pingable, web server accessible, and OTA updates from the dashboard worked). -
When trying to add the device manually to the Homey app (using the correct static IP:
10.0.0.10and no API key), the app would always time out after ~15 seconds with a connection error. -
The ESPHome device’s live log showed the following during the connection attempt from the Homey Pro (IP
10.0.0.108):[D][api:160] Accept 10.0.0.108 [D][api.connection:1383] homey (10.0.0.108) connected [W][api.connection:1880] homey (10.0.0.108): Reading failed CONNECTION_CLOSED errno=128 -
The immediate
CONNECTION_CLOSEDerror strongly suggested a version or protocol incompatibility.
Solution:
-
We stopped the
latestDocker container and ranesphome/esphome:2023.12.9instead. -
After reflashing the device with this older firmware (and correcting the
ota:syntax in the YAML for the older version), the Homey app (manual add, same IP) connected successfully on the first try.
It seems the Homey app isn’t yet compatible with API changes in the late 2024 / 2025 ESPHome builds.
Thanks for looking into it when you have time!, no hurry because as i said downgrading the firmware worked
Edit: i now see that you stated that the app is no longer updated
Hi Andreas,
There’s a chance the app gets supported again in the future:
Hi Andreas,
I’m having the same problem. I have a bunch of Konnected devices that got upgraded to ESPHome 2025.10.x and I’m seeing the same CONNECTION_CLOSED error. Digging around I found this:
It’s labeled as a breaking change so I suspect this is the cause. There are also several open issues noting connection problems since upgrading to 2025.10.x
How did you downgrade it? also with existing devices?
If you have Home Assistant
You can use older ESPHome Version through the add-on store
