Smart Irrigation

A Home Assistant integration to optimize irrigation

Glossary

One word for each thing in the panel; these pages follow as they are revised. The code, the services, the entity ids and the attributes keep their names, so automations that use them don't change. The column "In code" gives that name.

When you translate the panel, use the word in the second or third column for the thing in the first; a language without a column yet is free to pick its word, as long as it keeps to one.

What it is Panel (English) Panel (German) In code
The water a zone's root zone has, counted from field capacity, in mm (or inches). Zero means it holds what it can; below zero it is short, above zero there is a surplus that drains away. Water balance Wasserbilanz bucket
What a zone is short of, the water balance below zero, as a positive amount. Deficit Defizit (negative bucket)
The largest surplus a zone keeps above field capacity. Maximum water balance Maximale Wasserbilanz maximum_bucket
How fast a saturated root zone drains, in mm/h. Drainage rate Entwässerungsrate drainage_rate
The water lost to evaporation and plants. ET0 is the reference value from the weather, ETc that value times the crop factor. Evapotranspiration (ET0, ETc) Evapotranspiration (ET0, ETc) —
The factor between ET0 and what the planting uses. Crop factor (Kc) Pflanzenfaktor (Kc) multiplier
The way a zone's water loss is calculated: from the weather (PyETO), a fixed amount (Static), or a value another sensor provides (Passthrough). Module Modul module
The sources a zone reads its weather from: a weather service, your own sensors, or both. Sensor group Sensorgruppe mapping
An online service that provides weather data and forecasts. Weather service Wetterdienst weather_service
How long a zone is watered at the next start, worked out from its water balance and its flow. Duration Dauer duration
What starts the watering: a time, sunrise or sunset, or the sun's position. Start trigger Startauslöser irrigation_start_triggers
A set of zones watered together on a schedule (full controller only). Program Programm programs
Smart Irrigation opens and closes the valves itself. Full controller Volle Steuerung full_controller
A soil or planting nobody picked: the zone is calculated with the value it started with. Not chosen yet Noch nicht gewählt soil_type / plant_type empty

Words that are not used

Instead of Say
bucket (in a text), Vorrat, Eimer water balance, Wasserbilanz
engine, calculation engine, Berechnungs-Engine module, Modul
mapping (in a text) sensor group, Sensorgruppe
crop coefficient, multiplier, Pflanzenkoeffizient, Multiplikator crop factor, Pflanzenfaktor

"bucket" stays where it is code: the attribute bucket, the action set_bucket (and, until they go in 2027.11, set_all_buckets, reset_bucket and reset_all_buckets), and the entity ids ending in _bucket.
