Das Auto, meet door slam
Volkswagen blocks Home Assistant by requiring client assertion
VW locks out Home Assistant and fans are calling it a self-own
TLDR: Volkswagen appears to have changed its login system in a way that blocks Home Assistant from connecting to cars, cutting off a popular smart-home workaround. The community is furious, with users calling it anti-user, anti-competition, and another embarrassing software blunder from a legacy car giant.
Volkswagen has apparently slammed the door on Home Assistant users, and the internet is reacting like someone just unplugged the smart home mid-coffee brew. Owners say the old login flow stopped working, even though Volkswagen’s own app and website still do, which has led many to one spicy conclusion: this wasn’t an accident, it was a deliberate move to block unofficial tools. For regular people, that means car owners who liked checking battery, charging, or lock status in their home dashboard may now be out of luck.
The comment section quickly turned into a full-on roast. One camp sees this as classic big company nonsense, with users mocking the corporate language around “non-approved third parties” and asking why VW is “shooting themselves in the feet.” Another group went bigger, turning it into a symbol of why traditional carmakers keep fumbling software. One commenter painted a savage picture of German executives in dark suits versus younger, more engineering-minded Chinese rivals, basically saying: this is why legacy automakers are losing.
But there was drama on the other side too. Not everyone was sympathetic. One commenter gave the cold-shower take: if you’re not an approved app, don’t act shocked when the company kicks you out. Still, the mood was overwhelmingly anti-VW, with one person literally crossing VAG cars off their next electric car shopping list. The darkest joke of all? Several users said VW support was so clueless it sounded like AI that lost the plot after one sentence. Ouch.
