Dave I have found that using non isolated serial to USB made up leads work most of the time , but as you add more leads to more devices they will stop working, you need isolated serial leads, I brought a Isolated 4 port USB to TTL UART FTDI from Duppa that will run 4 devices via one USB device along with 4 made up leads cost me $100 AU, Also if you install the large image of Victron Venus you also get to run Node-Red and SignalK, SignalK is great if you have a boat as it is a standard protocol with a lot of boat comms
Yes I recently read this on GitHub about DIY cables not working after awhile, I have since bought one from Victron to get the Galvanic Isolation Thanks for the tip.
Unfortunately the homemade usb cable you describe is not always reliable with all victron devices, I found you really need to use a Duppa isolated adaptor from Italy for total reliability, I saw this on Andys Off Grid Garage channel
Good question, the Pi 5 is really over kill for Venus OS the reason is a Pi 2 can run Venus even the 4 is completely under utilized , Victron hasn’t released any Venus OS version of the software for the 5 yet, I’m sure someone will just try and load the 4 version on a 5, it won’t run faster or have anymore capabilities than the 4 even Node Red or other large capabilities are nothing for the 3 or 4, it’s just not a large compute program you can load the program with an 8 G SD card it’s a very small piece of software.
I just found your video this looks good to the point I have a like and a sub do you have any videos of setting the pi up and stuff ? I just got in to the work of victron and would love to have a cheap hex style system in my van.
I also added a Pi 4 with Victron 150/45 and ordered the wires like you suggested but my PI is at the front of my RV while the Victron is in the rear basement with all my solar stuff. I am going to try and figure out if I can do a wireless usb hub/dongle or ? not sure what will work for a wireless connection. Of course the PI has blootooth and WiFi and you would think that the Pi could read the Victron which is also Bluetooth. Kinda confused but wiring all the way from back to front really is not an option.
Wally I have it on good Authority from the Victron staff that MPPT chargers and other VE direct devices like the Cerbo GX and Raspberry Pi’s can not connect via Bluetooth only connection possible is VE direct cables. You can but a super long USB extension cable I have seen them 20’ on Amazon not sure what the usb limit is but 40’ is probably doable hope this helps
@@davethemmp Thanks Dave! I am going to try this solution: I ordered Wireless HDMI Transmitter and Receiver, 2.4G/5G Plug & Play,100FT Range which is only 20 bucks on Amazon. I will put the raspberry Pi next to the solar charge controller and connect via Victron Ve cable and then connect transmitter to PI and connect receiver to monitor in the living room 35 feet away. I hope it works.
@@davethemmp Hey Dave. Well it worked! I added a HDMI wireless TX/RX from the Raspberry PI rear of RV to the 13" monitor in the front of RV. It was only 20 bucks on Amazon. So that solved the wiring and distance problem. The only adapter that the Raspberry needed was a micro HDMI adapter. The ports are already there.
I also made my own VE direct cable and it works perfectly. I have no latency or drops. I wired the PL2303TA USB to TTL Serial Cable and JST PH 2.0MM 4 Pin Female Single Connector like this: NEG NEG TX RX RX TX POS POS The two outside wires run straight red to red, black to black while the two center wires criss cross. which is the transmit and receive wires. Just noted all this for viewers just learning.
Hi Dave, thanks for the video. Can you please advise if the Venus OS over raspberry have an access from anywhere in the world or just via internal network and how to make it accessible over the internet.
With this, you should be careful although it’s cheaper now if you need to add all the different communication into faces and lots of other things you very much could be costing yourself a similar amount
I showed this option of DIY the cables but I have purchased the Victron cables they have galvanic Isolation required on a boat Vans can get away with DIY

I agree I have since purchased the Isolated ones from Victron for marine applications
However, for most common communication standards isolators exist and they are very cheap
This is a fairly new video (4 months at the time i am watching) , Have any readers here used a Pi-5 with Victron OS ?
Good question, the Pi 5 is really over kill for Venus OS the reason is a Pi 2 can run Venus even the 4 is completely under utilized , Victron hasn’t released any Venus OS version of the software for the 5 yet, I’m sure someone will just try and load the 4 version on a 5, it won’t run faster or have anymore capabilities than the 4 even Node Red or other large capabilities are nothing for the 3 or 4, it’s just not a large compute program you can load the program with an 8 G SD card it’s a very small piece of software.
Watching this and some other videos, cool projects.
Awesome, thank you!

I am Actually working on a video right now on how to setup the Venus OS on a Pi, it’s pretty involved to make it work like a GX device

Yes sir you can see the Venus OS over internet via the VRM internet portal
The Pi needs internet connection same as the Cerbo GX
Thanks, I’ll try this out !

@@davethemmp all may need it it just depends on if there is a random issue but you can get isolated usb to serial
another great vid
Thanks I appreciate it.
