FROM READINGS TO UNDERSTANDING

Get to know your tank.

Compare temperature changes with available sunlight and discover how your tank behaves overnight. Water use, backup heating and thermal delay all play a part.

Sunlight correlation

—

Association between hourly collector-plane radiation and tank warming. Needs 6 well-covered hours. Correlation does not measure efficiency.

Low-sun warming

—

Median temperature change with 5–150 W/m² radiation. At least 3 paired hours are needed.

Collection quality

—

Successful and failed polls in your selected time range.

Incoming sunlight power

—

Based on the latest hourly weather estimate and gross collector area.

Provisional gross area · not heat delivered to the tank.

What the numbers mean

Strong-sun warming uses hours with at least 300 W/m² estimated on the tilted collector plane. The assumed tilt affects these comparisons; collector count does not multiply W/m². Incoming sunlight power multiplies W/m² by the combined gross area; the next-24h estimate integrates that incoming energy. Gross dimensions include frame and gaps, so these are provisional incident-sunlight estimates, not thermal output or efficiency. Roof shading and evacuated-tube optical performance are not modelled. Nighttime cooling uses hours below 5 W/m² with a negative temperature change. Each group needs 3 paired hours. Net stored heat assumes a uniform tank temperature; a single internal sensor cannot account for stratification. This estimate is not total solar production. Temperature predictions need additional history and are not included.

Gross area uses width × height × collector count; depth is recorded only. Incoming sunlight estimates are not useful tank heat or collector efficiency. Tilt defaults to an assumed 40°. Azimuth: 0° south, −90° east, +90° west, ±180° north.

Database backups

EXPORT / IMPORT

Download a complete SQLite backup with readings, weather, settings and notification history. Backups include webhook authentication headers: keep them private.

Restore a SQLite backup · up to 100 MiB

Import replaces the current database and saved settings. A safety backup is kept in the server database’s backups/ folder. Queued notifications in the imported file are cancelled to prevent old webhooks being sent again. Your server access token and Midea login are not stored in these backups.

Alerts & milestones

YOUR RULES

Choose thresholds before enabling temperature alerts. Hold requires a sustained condition; reset margin avoids repeated crossings. Cooldown limits new episodes after recovery. Stale threshold is seconds. Fault alerts trigger on a positive error code.

Event	Threshold	Reset margin	Hold · sec	Cooldown · sec	Recovery

Persistent conditions send once. Failed deliveries retry up to six times. Receivers can deduplicate using X-MSmart-Event-ID. Alerts supplement your tank’s physical temperature protection.
