Self-diagnostics

Installation self-diagnostics — detecting communication failures and bad measurements

An unattended installation can run with an error for weeks. Self-diagnostics notices the problem first, tries to fix it and tells you what happened.

What you get

Problem detection

Device or connector offline, stale data, physically impossible values, mismatching sources.

Safe repairs

Retrying the reading, a controlled API retry, restarting the connector’s communication process, switching to a backup data source.

Limited mode

When data is uncertain, Energy Autopilot switches to the safe strategy instead of controlling blindly.

Loop protection

At most 3 attempts per incident (after 5, 15 and 45 minutes) and 6 actions per device per day. A problem that keeps coming back stops automatic repairs.

How it works

  1. 1

    HEMS constantly compares measurements with expectations.

  2. 2

    Each incident goes through defined stages: from detection, through repair, to closure.

  3. 3

    You get a notification with a description and the history of actions.

Details

  • Never: restarting the inverter, changing protection settings or electrical operations.
  • Alerts have a button that leads straight to what needs fixing.
  • Event log and connector crash dumps available in the panel.

What you need

  • Any installation in HEMS — self-diagnostics works from the first measurement.

Frequently asked questions

Will self-diagnostics restart my inverter?

No. Only “soft” communication-side actions are allowed. HEMS does not touch the inverter, protections or electrical circuits.

What does “flapping” mean?

A problem that comes back at least 3 times within an hour. Automatic repairs are then paused, because human intervention is usually needed.

How will I learn about a problem?

Through an alert in the panel and a push notification in the app on your phone and computer.
