JKBMS s Pylontech simulací

Souhrn tématu

V diskusi je popsáno, jak připojit pět let starý JKBMS k měniči s Pylontech protokolem pomocí ESPHome a ESP32. Autor využívá UART GPS port JKBMS a RS485 optoizolátor pro simulaci Pylontech baterie, čímž umožňuje monitorování bez nutnosti kupovat nový BMS. Sdílený kód a nastavení pomáhají zájemcům integrovat starší JKBMS do moderních systémů s Pylontech protokolem.

JKBMS s Pylontech simulací

Nový příspěvek od proasnet »

Už tu je něco podobného nespočetněkrát, ale jestli to někomu pomůže, řešil jsem jak připojit svoji 5 letou JKBMS k měniči s pylontech protokolem, která už byla monitorovaná pomocí ESPHome.
Samotná BMS nemá RS485, jenom port GPS (UART) a tam jsem měl připojený ESP32. Kupovat novou s pylontech se mi nechtělo, tak jsem hledal řešení, jak to zkloubit do jednoho ESP.
K ESP kromě JKBMS je připojený také RS485 optoizolátor, který je následně připojený k měniči, a ten vidí Pylontech baterii
