"""Proaktivní notifikace "auto doma + nepíchnuté + levné/přebytek → píchni ho".
|
||
|
||
Tenký orchestrátor: veškerá doménová logika (kdo je doma, odpojený, výhodná cena,
|
||
SoC pod cílem) i dedup jsou v ems.fn_ev_presence_nudge_due(). Python jen zavolá
|
||
funkci pro každou aktivní lokalitu a pro každý vrácený (= nově due, ještě
|
||
neposlaný) řádek pošle jeden Discord nudge.
|
||
|
||
Dedup je čistě v DB: funkce zapíše řádek do ems.ev_presence_nudge_sent
|
||
(on conflict do nothing) a vrátí jen ty, kterým insert skutečně prošel — tedy
|
||
jeden nudge na "epizodu" auta doma+odpojeno. Opakované 20–30min ticky proto
|
||
nespamují, dokud se auto nepíchne nebo neodjede (čímž se klíč epizody změní).
|
||
|
||
DEFAULT-OFF: funkce nevrátí nic, dokud není na vozidle
|
||
asset_vehicle.presence_nudge_enabled = true. Job tedy běží inertně.
