# batterie. Depuis le 07/10 il chauffe en HC de nuit les jours faibles

# l'heure — EDF si le reseau fournit plus de 300 W, solaire si la production
# couvre la maison, batterie sinon. C'est une ATTRIBUTION par heure, pas un
# comptage par electron : une heure moitie soleil moitie batterie est classee
