Modbus-integratie toegevoegd: https://github.com/senalse/ha-alphaess-modbus
(Hillview is de bron van veel AlphaESS modbus-integraties, deze modbus-aansturing is onder water ook hetzelfde. Senalse heeft deze doorontwikkeld naar een echte HA-integratie die te installeren is via HACS waarbij je out-of-box een grote set aan entiteiten krijgt en deze reageren ook erg snel, wat bijvoorbeeld weer goed is voor de grafieken.)

Deze voegt deze entiteiten toe:
- switch.alphaess_inverter_dispatch
- select.alphaess_inverter_dispatch_mode
- number.alphaess_inverter_dispatch_power
- number.alphaess_inverter_dispatch_duration
- number.alphaess_inverter_dispatch_stop_at_soc

Entiteiten die meetwaarden opleveren:
- sensor.alphaess_inverter_battery_state_of_charge
- sensor.alphaess_inverter_battery_power
- sensor.alphaess_inverter_grid_power
- sensor.alphaess_inverter_current_house_load
- sensor.alphaess_inverter_current_pv_production

De trigger kijkt naar:
input_select.dao_batterij_operating_mode
input_number.simulatie_batterij_vermogen

en de automatisering zorgt ervoor dat wanneer DAO zijn planning aanpast, de AlphaESS opnieuw wordt aangestuurd.

AlphaESS Self-Consumption setting:
AlphaESS in de Self-Consumption mode gezet, zodat wanneer DAO niet specifiek aan het laden of ontladen is, de batterij gewoon gebruikt wordt voor huisgebruik en opgeladen kan worden via zonnepanelen.

In het kort:
DAO stuurt de 2 helpers aan, de automatisering reageert op de helpers, de automatisering stuurt de batterij aan via modbus

Alternatief:

bovenstaande stuurt de alpha aan via dao via de power feedin (grid) optie, maar de hillview integratie stuurt de inverter aan met laden en ontladen en niet op grid niveau. Je kunt ook aansturen met "from battery" om hem volledig aan de dao planning te kunnen houden.

Uitleg:
DAO → AlphaESS Mode 2 via Hillview — automatiseringstoelichting

Achtergrond:
De Day Ahead Optimizer (DAO) berekent elk kwartier een optimaal laad/ontlaadplan voor de batterij op basis van day-ahead stroomprijzen. De AlphaESS wordt aangestuurd via de Hillview integratie in Home Assistant, specifiek Mode 2: State of Charge Control, waarbij je Power, Duration en Cutoff SoC instelt.

Automatisering 1: DAO → Mode 2 Trigger: Elke 15 minuten op :00:15 (15 seconden na het kwartier, zodat DAO zijn berekening heeft afgerond).

Condities:
DAO moet actief zijn (operating_mode != Uit) Als DAO aan staat én de balance switch aan staat, wordt niks gedaan — de omvormer regelt dan zelf nul-op-de-meter

Vermogen (dao_from_battery):
DAO geeft het gewenste batterijvermogen als kwartiergemiddelde. Bij een korte dispatch (bijv. 8 minuten) wordt dit vermogen omgerekend: vermogen × 15 / duration, zodat de juiste hoeveelheid energie in de kortere tijd wordt geleverd. Begrensd op ±10 kW.

Duration:
Berekend op basis van dao_stop_inverter. Als DAO geen stoptijd heeft ingesteld staat deze op 2000-01-01, dan wordt 15 minuten gebruikt als fallback.

Cutoff SoC:
DAO's berekende SoC ±2% marge, zodat de omvormer iets verder laadt/ontlaadt dan het exacte target. Minimaal 15% bij ontladen.

Dispatch herstart:
De duration wordt eerst op 1 minuut gezet, dan na een korte delay op de echte waarde. Dit forceert altijd een state change waardoor Hillview de dispatch herstart — ook als de duration niet verandert. De boolean wordt alleen aangezet als hij uit staat.

Automatisering 2: Dispatch off → batterij stilzetten

Trigger: Als alphaess_helper_dispatch op off gaat.

Doel: Als de dispatch afloopt (target SoC bereikt of timer verlopen) valt de omvormer terug naar zijn standaard modus. Als de balance switch uit staat betekent dit vrij laden/ontladen zonder sturing. Door Mode 2 opnieuw in te stellen met power 0 blijft de batterij stil totdat de volgende DAO-berekening op het kwartier een nieuwe opdracht geeft.

Conditie: Alleen als de dispatch niet door de DAO-automatisering zelf of de DAO off-automatisering werd uitgeschakeld, DAO actief is, en de balance switch uit staat — als de balance switch aan staat regelt de omvormer zelf nul-op-de-meter en hoeft er niets te gebeuren.

Automatisering 3: DAO uit → batterij stilzetten

Trigger: Elke 15 minuten.

Doel: Als DAO uitgeschakeld is wil je voorkomen dat de omvormer de batterij vrij laadt of ontlaadt. Power 0 houdt de batterij stil zodat PV ongestoord naar het net of huis gaat.

Conditie op PV: dao_from_pv < 50W — bij hoge PV-productie op DC-installaties kan dit anders interfereren.
