We moved this year and couldn't get my old(ish) Roomba i5 to work in my new wifi easily. I've been meaning to debug the problem further, but if it can be confirmed that it's an iRobot issue and there's nothing I can do, it would save some effort.
It sucks, though, that I can use my fucking vacuum cleaner because a remote server of the manufacturer has decayed. Does anyone know if there are robotic vacuums that work fully locally without remote servers?
I can't give 100% confirmation, but it was working one day and not the next, with no changes to my network along the way.
Yes, it is an absolutely infuriating state of affairs and one could claim we were naive to not see this coming. Needing to be this cynical is the root of crisis of trust. The only thing we can rely on is that everything is a race to the bottom.
That being said, there aren't many commercial offline robot vacuums. I bought a secondhand roborock unit that is on the approved list put out by valetudo. I got one that required some disassembly to flash, which maybe lowers the market price. It's been working great and the home assistant hooks are working. There isn't a company on the planet that is in between me and my robot vacuum now.
