Cerbo def worth the 200ish. No hassle and probably cheaper in the end.
Your VRM link goes to the HBR instance and I can't see a way to see a bigger listing? That forecast section is pretty sweet looks like I'll have to get a cerbo-s versus making do with bt connectivity and virtual connect.For a small, simple system, an RPi is fine. You might have noticed "Steve's RPi" in my VRM list. That's just an RPi I'm using to monitor a JBD BMS battery.

Using a pi instead of a Cerbo doesn't get you the included relays in the Cerbo for controlling external devices, generators, etc, (but you could add external ones) but if you were looking at the smaller -S Cerbo you are probably ok. Take a look here, be careful of which pi you use, etc, and enjoy:Cool. Yeah, been doing Linux since Slackware 0.94 (back when you could install Linux from 4 1.44mb floppies...) I have pi's stacked all around here - use to use them to control cybercoin mining gear.
There was a big surge in pi pricing that's just recently eased off to reality levelsI wonder why people don’t offer Pi all programmed ready to go on the resale market.

Off the top of my head...
RPi were almost impossible to get for a few years, and are still comparatively "rare" and expensive.
It's crazy easy to do.
RPi people are already cheap, somewhat savvy and aren't likely to pay a premium for the effort.
I remember looking and small kits on Amazon in 2022 were almost a wash price wise with a cerbo (minus the display) once you factored in all the USB converters.Off the top of my head...

You cab get a relay hat with a variety of specs and voltages. Slide it over the gpio and it works. Wouldn't surpries me if the common used pi ve software isnt already coded for a specific one.Biggie for me is the Pi's lack of relay ports. Yeah, one can add them to the GIO pins, but by then its likely the Cerbo is cost competitive. Close already once, as someone else pointed out, you factor in cableing. Plus no CAN support for batteries.

Got to be just a bit careful is your using a AC-DC power supply for the Cerbo and that power supply is on the AC OUT side of inverter. Apparently the inverter won't power up until the Cerbo does, so you can get yourself in a catch 22 situation - or so I've read. Therefore, powering off the batteries directly is superior. That's easily said with 12V systems, not sure what to do for a 24V or 48V system.For what it is worth, I power my pi via a POE Hat, which is connected to a DC-powered POE network switch which itself is connected to my battery. I have a PtP WiFi antenna back to the house, also on the same switch....For a real cerbo, I'd probably do USB power from the battery if I didn't want to go AC for the Cerbo with a small ac-dc power supply.
CAN hat
The only issue I've heard about is the double sometimes switches addresses during reboot and changes the battery device ID number.
Here is what I do for CANBus to my EG4 LLv2 from the pi:CAN hat
