Likely causes

How to fix or prevent it

  1. Check that the router or access point is on, and that other devices can connect.
  2. Move the product or the access point closer, or add a repeater.
  3. Re-enter the Wi-Fi details if the network changed.
  4. Check cables and connectors.
  5. To prevent it: a stable access point within good range, and a wired link for important equipment.

What the HEART does by itself

It goes on working without the network: it keeps watching, keeps private events on the product, and may try to reconnect. It sends this alert when the link is back, so a watcher may first see system.flatline. It resolves when the link works again.

When to call service

If the link drops every day, or the product cannot rejoin a network that works for everything else.


Inside a message a code is written bare, "code": "storage.full". In logs, tickets, documents and searches it is written HEART storage.full. Things that simply happen, such as system.started, are event types, not faults. The codes are defined in Part 3, Section 5.4, and their H-numbers in Section 5.7. All of it, as data: fault-codes.json.
