• Mention Update advice after falling off the update treadmill · Reddit · 2026-10-06

  I have a ClareOne alarm panel that I was basically only using for door chimes. The house already has Clare 433 MHz door contacts and a PIR motion sensor, so I really didn’t want to replace perfectly good sensors just to get them into Home Assistant. I couldn’t find an existing C…

• Mention 2026.9.0+ Bricks HA Cloud · Reddit · 2026-10-01

  Did a bunch of diagnosis- while HA thinks its online, the DNS resolution keeps failing. There are a good number of threads about this being a recurring issue sometimes. Manually setting bypass sometimes works temporarily but the cloud link will quickly stop working after a resta…
