Hey everyone, I wanted to share my recent experience with integrating my Roborock E25 vacuum cleaner into Home Assistant using the xiaomi_miio.vacuum integration. Initially, everything was working smoothly, but after a few days, the vacuum suddenly disappeared from the frontend. I was a bit puzzled and started digging into the logs to figure out what went wrong.
The logs showed an error related to timezone handling, specifically an AttributeError: ‘dict’ object has no attribute ‘upper’. This was a bit confusing, but I decided to approach the problem step by step. I checked the obvious things first—ensuring the IP address was correct, verifying that the vacuum still worked with the Xiaomi app, and even power cycling the device. None of these steps resolved the issue.
After some research, I came across a suggestion to update the firmware of the vacuum cleaner. I wasn’t sure if this would help, but I gave it a try. Lo and behold, after updating the firmware, the integration started working again without any issues!
This experience taught me the importance of checking firmware updates, even for devices that seem to be working fine otherwise. It also highlighted how valuable the Home Assistant community is for troubleshooting and finding solutions. If anyone else is experiencing similar issues, I’d recommend checking for firmware updates as a first step before diving deeper into the logs.
I hope this helps someone out there who might be stuck with a similar problem. Happy automating!
