Solar Assistant

Už jsem se na to koukal, je to asi to, co by se mi líbilo, jen v seznamu není typ BMS, kterou mám (JK-PB2A16S20P v15). Bude to fungovat i s touto BMS?

Nevím, ale neočekávám, že by výrobce změnil způsob komunikace a sám si komplikoval život.

Zda sa ze problem vypadavania USB je vyrieseny.
Odsledovane uz dlhsiu dobu.

Chyba bola pravdepodobne na poskodenom filesysteme.
Po oprave fsck -fy -C0 /dev/sda1 to slape ako ma.
Cely adresar /var je teraz primontovany na usb kluc.
Takze na flash pameti je len system , ziaden zapis.


Zatial sa mi nestalo ze by zber dat vypadol.

FS za vzdy poskodil ked sa vypol RP. Spravne musi byt najskor shutdown.
Lenze pri vypadku elektriny to jednoducho vypadlo.
Preto som zacal napajat RP priamo z bateriek. Treba k tomu menic na DC-DC 60V->5V.
Co je tazke zohnat , pretoze nie kazdy vyhovuje.
