Likely causes
- The Wi-Fi access point or router is off, restarting or out of range.
- A changed Wi-Fi password, or a router replaced by a new one.
- No mobile signal, such as a tracker in thick woods or underground.
- A cable unplugged or damaged.
- The network operator or internet provider has an outage.
How to fix or prevent it
- Check that the router or access point is on, and that other devices can connect.
- Move the product or the access point closer, or add a repeater.
- Re-enter the Wi-Fi details if the network changed.
- Check cables and connectors.
- 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.
