Homey recently showed me a lot of OTA updates for my Matter devices.
The updates for my Heiman smoke sensors went relatively smoothly. Only one device stopped during the process, but retrying the update worked fine. I was also able to update one IKEA Bilresa button, although it took at least 10 attempts.
However, I am now unable to update the two remaining Bilresa buttons or any of my window contacts.
I tried pressing the middle button every 10 seconds during the update, but that did not help. I also placed the buttons in the exact same location as the one that eventually updated successfully, but still no success.
The update process starts normally: first “Waiting for device”, then “Updating”, and the percentage starts increasing. Sometimes it only reaches 3%, sometimes it goes as high as 78%, but it always ends with “Update failed”.
For my Aqara U200, clicking the Update button in Homey immediately shows an “Invalid arguments” error. In the Aqara app, however, the firmware is shown as up to date.
From what I have read, Bilresa buttons and window contacts seem to update fine under Home Assistant. So I am wondering: what is going wrong with Homey here? Or am I missing something?
To update the billresa buttons, you have to try… and try… and try again…
It’s as if, with every unsuccessful attempt, it still updates a little bit. After 4 or 5 retries, they update.
I updated all my bilresa buttons with a lot of patience, first by “waking them up” (ie pressing the button), then starting the update and doing retry after each error
I cannot really say how well it works in general. In my setup it often dropped from the network and had to be repaired. However, since firmware 1.7, the device seems to have become really stable.
According to Heiman, firmware 1.7 also added support for triggering the alarm from automations. However, I do not see such a card exposed in Homey.
I was told that Homey may intentionally suppress this function, possibly for legal or safety reasons, but I cannot confirm whether that is actually the case. At the moment, I can only say that the functionality seems to exist on the device/firmware side, but is not available as a Homey flow card.
They are affordable and monitoring or triggering a flow when they detect smoke works very well.
I can simply tell you that I was able to update all my Eve devices via my Homey Thread network without any problems after using the battery trick. You might find an explanation here.
I can just tell you that it does nor work with any Ikea device for me. What I see is that it is like playing lottery, some rare cases, probably less than 1% it works.
