Hello, new install. All victron. A lot of stuff seems to be from RV community and/or folks with multiple brands trying to get things to talk to each other. I have a boat on a mooring with no internet connection. I want to do a simple (seems to me) change with node red to keep my orion dc/dc from charging when Im on shore power (not often). Orion seems stuck in bulk mode all the time (settings?) Regular lead acid start batt, 12v victron Li batts,(2) lynx bms, phoenix 43 12/50 (1+1). Aux on phoenix goes to start batt. Orion reads phoenix aux input as alternator input, and starts up.
Question…does Cerbo have to be connected to internet to let me play around/learn node red? Figure I know the answer, just want to hear it. Is there a way I can play with node red at home and then download a change when I get an internet connection, I suppose is the main question?
The amount of information out there is massive, sorting thru all of it takes days. Just need a couple of y/n answers(hard to find around here as you know :)) can figure it out from there.
No, nodered runs locally over the LAN. Internet is only needed to update the GX image to the large type that includes nodered.
You can install a test venus install at home on a Pi or supported device to experiment.
Flows can then be exported and imported elsewhere, some changes will be needed after import so the devices and nodes are pointed to the correct instances.
Thanks so much for the reply Nick. I was able to get to the node-red on the boat. If I could only remember my pass word! I’ll dig it up
All I want to do is kick off the Orion if I’m on shore power. Thinking about it more…is that necessary? Do they actually “fight” each other? It’s just another load for the system to figure out…between the cerbo and bms, shouldn’t matter, although they may have different charging algorithms. My Orion seems to just hang in bulk (no idea why, new to all of this…another thread..). Does one override the other? I think I’m just trying to be cute on this…I’m only going to be on shore power to get stuff back to peak. Rest of the time alt will charge start batt, and house. I see most people have an elaborate system and tons of solar, etc, trying to do things…I have a very simple system. Do I care if both are running at the same time in the few times I’m on shore power? Seems to me, same thing if I start my engine at the dock…is that bad? IDK. Admit was just curious about playing with node-red and things I could do, but we know how curiosity and the cat turns out!
Feel like Forrest Gump reading some of these posts…I’m not a smart man, but I do know what computer logic is Don’t know how old you are, and don’t fall out of you chair laughing, but I kicked butt programming basic and fortran! Actually googled LAN just to make sure it stood for what I thought it was!
I’m thinkin a should just let sleepin dogs lay on the orion/IP smart charger thing. Just don’t want my boat blowin up on the dock one night! Coast guard was all over the radio yesterday about a boat on fire at some Puerto Rico marina.
Thanks again for the reply earlier…you ever on St Croix give me a shout, I’ll take ya sailing.
Psychologists would say the hallmark of a smart person is knowing their limits and underestimating their abilities, so maybe you’re not giving yourself enough credit
you ever on St Croix give me a shout
Deal.
When I started with computers as a small child, we learned logic via logo..
Then it was programming basic on a ZX81/Spectrum, eventually some assembler, pascal and finally C.
It has all changed a lot but the basic logic is the same, not difficult to learn.
As much as I despise all things AI, one of the areas it is really strong at, is helping to teach programming in modern languages.
I don’t encourage using it to do 100% of the job, but rather breaking down the steps and functions so you can learn to be self-sufficient.
My philosophy is always to Keep it simple. When you’re mobile the consequences of it going wrong are somewhat more severe than my pool pump getting a life of its own.
