FVE s podporou z DS

[rva]

U elektromobilu chci vyšší dobíjecí proudy z fv elektrárny - počítám s regulací do nějakých 32A (až vyměním současný jistič 25 A) dle:
1. kolik okamžité energie z FV panelů je k dispozici
2. kolik je k dispozici volného výkonu měničů
3. abych netrápil baterie vysokým vybíjecím proudem.
Čínský "wallbox" je integrovaný v HomeAssistant přes tuya (mám ho přes tuya local, takže nepotřebuje cloud) a umožňuje za dobíjení měnit proud. Ne teda z jedné hodnoty přímo na druhou, ale když nastavím jiný proud, tak na chvíli přestane dobíjet a pak začne na nové hodnotě proudu. Zvažuji jestli v automatizaci pak nesledovat i napětí na wallboxu. Pro detekci případného uvolněného kontaktu a vypnutí dobíjení než někde začnou sršet jiskry.

Podívej se na soft evcc. Umí to milion wallboxu a truhle logiku, aby to něco nepresvihlo nebo vymezovalo to má. Do ha pak jde napojit přímo evcc

Díval jsem se na to. Výrobce wallboxu který mám jsem tam nenašel, třeba je to kompatibilní s nějakým jiným. Ale i tak jsem usoudil, že když mám HA, tak raději budu realizovat maximum v něm a když to půjde, tak nebudu instalovat další software okolo. Tuya zařízení nepreferuji, ale je pod nimi snad nejvíc věcí a cenově jsou atraktivní. Pro věci, kterých funkčnost je pro elektrárnu zásadní, dám přednost třeba Shelly.

Pár FV panelů je připojených na mppt regulátor EASUN 48100 (100A) a tak jsem doplnil sběr dat do HA pomocí převodníku RS485/TTL na esp32_C3. Na RS485 už ani nedávají konektor, tak se musí pájet. esp32_C3 mám s displejem, tak na něm rotují základní hodnoty.
