Hello it’s my first post here, but i’m a bit of a lurker that have digged a bit around the subject before.

First of, i own a decent little installation based on Victron solutions, (except my two LiFePo Batteries) to power my 4x4 RV.

  • 2x Ultimatron 12v 200Ah in //
  • Mutiplus II - 12/3000/120
  • MPPT 100/50 with 600w solars pannels
  • Orion TR charger 12/12 - 30A
  • Lynx distributor modded (BEP switch and Shunt directly mounted + self-powered board)
  • 2x Battery Protect 65A
  • Raspberry PI 3B+ with Venus OS + some little boards to Ve.Direct and a 7" touchscreen

The main subject that i would discuss here is about the legitimity of RPI to still act as a CerboGX for (small) DIY application, because i’ve heard a lot about issue like the graphics acceleration on 5.32+ Gui-V2 and difficulty fo work around ADC and resistive tank senders ?

And on the other hand, discuss about the extension boards (HATs) that are available on the market that would help the RaspberryPI to plateform with succes the task of beeing the center of a Victron installation.

Somes features for exemples looks usefull like :

  • SMPS power-supply.
  • RTC Clock.
  • Relays.
  • CAN interfaces.
  • ADC for resistive levels senders.

What do you think about this one : https://thepihut.com/products/multi-io-8-layer-stackable-hat-for-raspberry-pi ?

By the past a user called Rob Duthie designed an extension board called the Stetson that was kind of optimised for the usage with VenusOS and an alternative to CerboGX.

But it seem to have been discontinued… ? https://communityarchive.victronenergy.com/articles/38710/victron-raspi-hat.html

Thank’s you for reading, if you hare an Hatted RPI User, please let me know what’s style of hat you like on you own :slight_smile:

I have a “Waveshare RS485/CAN-Hat (B)” on a Pi 4, which I use to connect to my JK-BMSes via RS485. I bought it because the CAN and RS485 are isolated (from the Pi, not from each other), it could also power the Pi from up to 28V, but I’m not using that with my 48V system…

Nice and cheap, that allow you to work around with CAN bus. But still a bit too less function for me.

Hello, good initiative, as said upper, an RTC clock and a 12-24vdc input SMPS would be nice.

I already own this product from DuPPa for the VE.Direct communication with my Victron’s devices.

ADC analog tank sensor that work out of the box would also be a massive improvement.
