Поменял ЕСПху и всё завелось из коробки. ХЗ что это было, но главное завелось. Результат не сильно понравился - в родной прошивке не хватает ограничений для нумберов, слабо представляю как ползунком из веб интерфеса подтянуть до 13.5 вольт что либо если там диапазон 32 миллиона, может для НА не критично, но в целом почему бы сразу не добавить.
С другой стороны - значения не меняются и имеют какие-то не интуитивно понятные названия.
Кто может подсказать можно ли управлять float и charge величинами? И на каких оно адресах? То что получаю сейчас не похоже на мои настройки инвертора - Inverter Battery high voltage 15.0 V ; Inverter Battery low voltage 11.3 V ; PV Charger Float voltage 13.6 V (на вид оно, но подписан как ПВ - тоесть речь о солнечной, а не городской, или не важно?);
И что значит PV Charger Absorb voltage 14.2 V ?
Пока ещё колдую, но может кто ответит и пояснит, если интересно для себя пилю прошивку тут https://github.com/cahbegit/HA/blob/main/esphome/must.yaml, убрал все упомнинания про PV так как нет панелей, может перебдел?

диапазон 32 миллиона,
зависит от step:
речь о солнечной, а не городской
не важно
