Protocole pour comprendre pourquoi le Cerbo ne voit qu un pack sur deux

Le hub reconnait les deux groupes — LED verte et trois bips, son accuse de
reception — mais le Cerbo n en enumere qu un : 4 modules et 400 Ah la ou le parc
en compte 9 et 650.

Le releve de reference apporte le fait qui manquait : a 20:14 les quatre US5000
debitent 24 A au total pendant que le Cerbo annonce 41 A au parc. Les 17 A
d ecart sont le pack 2, qui porte donc bien du courant sans etre enumere. Le
courant mesure au shunt n est pas un indicateur d enumeration — seuls
nombre_de_modules_en_ligne et capacite_installee le sont.

Quatre etapes par risque croissant, la premiere ne touchant a aucun cable : un
redemarrage du Cerbo, l inventaire ayant deja change une fois le 13/09 a 21:35,
evenement isole verifie comme n etant pas un redemarrage de Home Assistant.

Regle de securite tiree de l incident d aujourd hui : fermer EDF AVANT toute
manoeuvre. Couper la communication du BMS arrete la gestion batterie, donc l
onduleur, donc la maison — 72 secondes dans le noir a 16:24. EDF deja ferme, la
maison passe en direct et ne voit rien.

L etape 4 renvoie a la documentation constructeur et n avance aucune theorie de
cablage : sur du materiel batterie je ne raisonne pas de memoire.
