Bazén: sezóna (schedulable), filtrace dle teploty vody, Loxone čidla
- V092: ems.loxone_sensor + telemetry_loxone_sensor (hypertable) — generické čtení Loxone hodnot (poslouží i ohřevu/akumulačce); pool sloupce teplotní funkce (ref/base/per_c/min/max) + water_temp_sensor_id - R__098 fn_pool_daily_runtime_min: clamp(base+per_c×(t−ref)) z poslední teploty <24 h, fallback daily_runtime_min; JSON detail pro UI/solver - collector poll_loxone_sensors: /jdev/sps/io/<name>/state, LL.value parse, no-op bez čidel - sezóna = schedulable přepínač (dokumentováno vč. SQL); hranice filtrace × ohřev TČ (oddělené logiky, sdílí jen čidlo) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
