A quick tip from a network engineer. Document every single connection in visio or an equivalent software. Print that out and laminate it. Document all your IP addresses you use and be sure everything is statically assigned. Make sure you have redundancy factored in. Don't just build 1 SD card build 2 so you have a backup in case the primary fails. label both ends of every cable so you know where it is going to / where it is coming from. These small things will save you immense headaches in the future.

One little tip on the newer Pi's from my experience using them as embedded monitoring systems, load your OS onto a really good usb3.x stick (or even better a proper nvme/pci drive) as opposed to an sd. I have had an almost 100% failure on PI's using sd cards (from all different manufactures and quality levels) when putting them into a real production environment. most if not all SD cards just are not designed for the constant read and write cycles that a main hard drive on a pc experiences. I know you had mentioned you were likely going to be using a different PC on the final system but might help a little with some of the headaches.

You may want to run your box cooling fans on a relay using a bme280 (temp, press, humidity) and node red software to minimize power consumption. Since the bme280 is i2c, you could also monitor the box temp in KIP.

Great video, love the board, I used to do this at work, I am an industrial electrician, I used to build panels with AC drives PLC’s and computers controlling industrial manufacturing machines, same process as yours then move to an enclosure when fully functional Looks like we are on the same wave length with our projects I now monitor pi cpu temp to determine box cooling keep up the great videos I’m learning from you 😂

This is a really cool project! Excited to see where you take it. As someone else pointed out, the SD card on your pi is the single most likely thing to fail. I would strongly recommend you use an SSD instead of an SD card if you can help it. If you must use an SD card, invest in a "high endurance" card. Several brands make them - most will be branded as "high endurance", "industrial", or "edge". Still, an SSD is definitely the way to go IMO. Edit: I believe the pi 5 has a dedicated PCIE interface, that you can use to directly attach a PCIE (NVME) SSD. If this were my project, I would do exactly this.

Not sure how I came across this video (probably doesn't help that I'm friends with @DeadlyDragon_) but as a fellow Floridian who does IT for a living, I love this project. I've always had fun with OpenCPN and a cellular modem when on friends boats. Also, I'm jealous of your test board with all the NEMA connections and all the labeling. Keeps making me want a boat...

Oh, man, that's such a joy to see that you can do such things yourself and on a limited budget nowadays :)

Running VNC probably also consumes alot of resources from the PI, better connect directly to a monitor and if this is going run over the network in production run it headless(no ui/displayserver installed) and if possible a webui on another PC (prob need to configure alot over SSH if you can do that).

I do a lot of network installations on island homes where there is a lot of sea blast, so similar environment to a boat. If you can get away with not bringing outside air into your enclosures for cooling, it would be better to run things a bit hotter that bringing that salty air into your enclosure. I have a lot of PoE network switches in sealed enclosures, and they run pretty hot because of the lack of external cooling, but I have found that actually is still better than bringing in external air. Even though you are exhausting air, it will still be sucking in air from somewhere. If you do need some active cooling of the enclosure, it might be better to move air around the inside of enclosure and move some of the air past a heatsink that is coupled to the outside, but doesn't let any air in.

Do you have 4.7k pullup resistors on the ds18b20 temp sensors? If not you will see junk data.

Cool!

Agin just use Honme assistant as the core to control and monitor all the systems. Reinventing the wheel but doing it worse . Most other open sourced tools you need can be integrated easily enough.

Tip: Sdcard have a slow read write performance that could be the cause of it crashing. You might want to consider using a ssd drive instead. You can get a 512gb ssd cheaply these days. Also Sdcard tends to go bad easily.

Very cool. Congrats. Sometimes playing with boat stuff is more fun than boating

I don’t think the whaler needs this lol😮

Are you doing fuzz testing?

everything wireless would be so much easier...
