Hi all,
I have an EG4 48v Lifepower4 100ah server rack battery (NOT the LL version) and a raspberry pi running Venus OS acting as a Cerbo GX to monitor my Victron solar charge controller and inverter.
Is it possible to connect the battery to the RPi/Cerbo as a device so it can see SOC?
I have the USB to RJ45 cable that came with the battery and I can see the battery fine on my laptop with the EG4/ Qualtech BMS Test software but I'm unclear on whether it's possible to connect to the Raspberry Pi or not.
Unfortunately, the LL version having a different BMS and communication protocol is muddying the waters of what I can find online.
I tried installing the dbus-serialbattery package but couldn't get it to work.
Before I keep spinning my wheels here does anyone know for sure if it's possible or not? Or would I have to buy EG4's "LiFePOWER4 Communications Hub" to do it?
Thanks in advance!
P.S. I think my question may be the same as here, but since I have the 48v and I'm using VenusOS, it might be slightly different so didn't want to hijack that thread:

EG4 to Victron Cerbo over RS485?
I have a V2 EG4 12v 400ah battery. The manual and front panel show RS485 ports on the front. Can I connect that to the Cerbo GX to get Battery monitor information into my VRM? Battery: https://eg4electronics.com/categories/batteries/eg4-lifepower4-12v-400ah-lithium-iron-phosphate-battery All...
