Raspberry Pi 4b beult with venus os (series)

[Suijkerbuijk]

I have beult my Raspberry pi4b with screen and heatsink's for the victron mppt and inverters
This is a topic how i have beult .
What you need .
How its done easy .
Links from Dutch Amazon parts
But i set the parts numbers with it .

So the start .
Whats is a Raspberry Pi serie
Its really a mini pc arm base systeem that you can beult and program .
In this case we gone make one with Victron venus os support.
Its a cheap solution for the venus gx systeem what cost a lot of money.
In that attach files you see what i use for the this beult .
I set YouTube from other people that help and explain more than i can do .
Its more easy that way and my English is not all the best .
For the rest the systeem is working process means i adjust over time .
I use a Raspberry pi4b and not a Raspberry pi5 serie
The reason is heat and the power use from the pi5 that use a lot more and have to be active cool.
And you do not need that extra power for the setup

So what i gone use for this.
Raspberry pi4b 2Gb model
A heatsink for this unit
A case with a 4.3 monitor (have the space for a heatsink)
And somting to power this systeem .

What makes it special? Each port has the digital isolator. The computer and your target board are electrically isolated. The 4 ports can work at different voltages and the ground is not in common. The noise coming from your computer doesn’t enter in your target board, this can be useful when you...

You can use multi wifi adapters.
One in your Raspberry Pi and a usb .
This way if you like you can make a fall back system.
In my case if i'm thare the wifi onboard of the Pi connect to my phone .
If i'm away the other usb wifi adapter go to the wifi point from the port whare my boat is .
Its switch automatic .
How it works
First install the os.
Than connect pi wifi first to a network.
After that stick a usb wifi in .
And select a other wifi point for that one and your done

Small things with venus os and no start.

Venus O/S cannot run from USB mounted drives, it must run from /dev/mmcblk devic
So you need to use a sdcards by the pi series up to pi4b .


Warning i upload multi time for i'm done with this .
So long this teks on it at the end .
I'm not done write this
Thank you for understanding.

The git hub “setup helper” is a godsend for getting my pi up and running.

I love using Venus OS on RPi. I have mine installed on a RPi Zero 2W, and Home Assistant talks to it over MODBUS/TCP (thinking of switching to MQTT though). My biggest problem right now is if the power drops. I'm taking a look at the video you posted about that. I have several RPis that are in danger of power loss, which I want to protect.

You can set some battery back up in to it.

Here you have some models you can select

I've tried a few options from Amazon, but they all sucked, frankly.

Powering the RPi from a battery is easy. The hard part is the next step of making that into a real UPS that does not allow the RPi to lose power when the power source has problems, and to shut down the RPi when the battery is low, but not yet dead. I don't want my devices to shut down immediately, but to keep running and only shut down if the battery gets low before the power is restored. So far, everything I've found pre-made is missing one critical feature or another. So, I am making my own (one of these days). I want the ability to proactively let the battery cycle down and then recharge it, to keep them from degrading over time due to infrequent discharge. Also I must be able to just press a button to have the device boot up or shut down, or even monitor the power and do those automatically.

For the button i have set a YouTube link for it.
Even a hardware button can be use

How to add a UPS to your Raspberry Pi projects (and do it on the cheap)

Want your Raspberry Pi to carry on running when the power goes out? You need an uninterruptible power supply. Here's how to add one.

With this the Raspberry see a battery .
So i think you can use this with program to shutdown if the volts go low.

This is really venus os problem on a pi.
I do not think you can shutdown by low volts .

My victron SCC has a load port powering one of these

https://a.co/d/ik4o0sp

They also run off 24v so no issues powering it directly from the battery bank.

My ra pi4 with display and adapters draws about 7-8w, victron connect says about 160wh/day.

It’s an off grid system so yeah it’s an ups to start.

I do the same .
I have set a other model beult in usb charger
And use the load outputs from the victron 75/15 for connect that usb charger .
Program the Victron that the load output is connect to the battery..
This way the pi is 24/7 with power.

Its about 0.3a on 12volt use 3.6watts

This is what powers my Home Assistant and Venus OS RPis on my RV for now, until I get a good UPS circuit for them.

It's plugged into the HA Pi, and the Venus Pi is getting power from the HA Pi from a USB port.

They make 48v to usbc raspberry pi power cords.. I use the solar batteries .. and no power outages

I use a PoE Hat to power my pi 4b with VenusOS. The Ethernet port is plugged into a DC powered PoE network switch, which itself is hanging off my solar battery pack.

I run my barn with solar, and a point to point WiFi antenna also hangs off the PoE switch, pointing to an identical antenna at the house, which is how I get VRM for my system.

I like the idea of a PoE hat. I'm using a DC PoE adapter to power my Access Point and WiFi uplink in my RV.
