Data sources

Data sources decide which reading comes from where. When more than one source can report the same value, LocalSky picks a winner per reading, and this is where you steer that. Edit it under Settings, then Devices, then Data sources. Changes apply to the live engine on the next reading, with no restart.

Per-field priority and backup chain

Each headline reading (temperature, humidity, wind, rain, pressure, solar/UV) has an ordered chain of sources. The top source that is reporting now wins; if it goes quiet the next one takes over, so a reading is never lost.

  • A reading you have not touched shows the smart region default order, tagged Automatic.
  • Drag a row, or use the up/down arrows, to make your own order, tagged Custom. Reset to automatic drops your custom order.
  • Each row is badged with the honest nature of that source for that reading: your device and measured and radar measured are real measurements, real-time is a live analysis, and model forecast is a prediction. So the same cloud service can read “real-time” for temperature and “model forecast” for rain.
  • A live marker shows which link is reporting now, which are on standby, the backstop at the end of the chain, and any that are off.

No weather hardware? A cloud weather service can supply any reading’s current value, so the chain is where you decide which service backs up which, even with no local station.

Forecast source

A separate picker chooses which service drives the whole forecast: the daily and hourly outlook, the rain expected tomorrow, and the evapotranspiration estimate the engine waters from. “Auto (follow the chain)” keeps Open-Meteo (free, no key) as the low-priority failover; pick a provider to pin it to win regardless of ranking. A pinned source that goes offline still falls back, so a pin never blanks the forecast.

What lives elsewhere

Soil moisture is governed per zone, not as a per-reading chain, so it is bound in the zone editor via each zone’s soil sensor, not here. The underlying config keys these controls write (field_source_chains, field_source_overrides, and forecast_provider) are documented in the configuration reference.
