Reconnecting or swapping a device
Sign-ins expire and hardware gets replaced — here's how to recover cleanly.
A link says "Error" or "Reconnect"
Sign-ins expire from time to time. On the Links page, a link in error shows a Reconnect action — tap it and sign in again with the same account. Nothing is lost.
Replacing hardware (e.g. Honeywell → Hive)
- Fit the new hardware and add its link on the Links page.
- Its devices are discovered — drop them into the same zone.
- Remove the old link once you're happy.
Every link row shows its status — Connected, Connecting or Error — plus when it last had data, so you can spot a problem at a glance.
