Blatant self promotion, we do this at some scale: https://floathub.com https://floathub.com And there's a guide to using our open source software-only option on a Pi: https://medium.com/@floathub/open-source-boat-monitoring-7ea8b97c5acd https://medium.com/@floathub/open-source-boat-monitoring-7ea... Contacting the author of the parent version now to compare notes :-)

I'd love to use this for overnight drops from the hi n dry. The one thing I didn't see mentioned is powering the unit with DC-only. I'm a PI newbie and I don't run an AC inverter on board.

  Super easy to power a Pi from DC only. Many (most) USB ports will work (the amperage draw can be a bit much for some older lighter-style USB power adapters). The power draw from our dedicated device (https://floathub.com/store https://floathub.com/store) is much lower than a Pi, but you don't get the advantage of a general purpose computer that can run other stuff at the same time.

    Appreciate the reply. It looks like there's a bunch of sensors I can hook up to the pi as well. Again, really appreciate you sharing this!

      There are some great sensor options out there and they are dirt cheap (cents or a couple of dollars). ESP32 and ESP8266 are my chips of choice and they are also very cheap. Some great projects are easily achievable from Arduino. It seems to be slightly looked down on as a platform, but I’m not skilled enough to know why. It has an IDE and a language that’s easy enough to use. There is also a huge community and a mass of projects out there. ESPHome is another excellent project which takes the coding down to just yaml config files and then you can makes automations one Home Assistant.

  Absolutely, and I certainly don't keep my inverter running when I'm not on board.

  you can get really small dc-dc converters that are suitable for the power draw of a pi. Take input of 12, 24, 36, 48VDC, whatever, convert it to 5VDC and power the header pins of a pi. take a look in some of the subsections here: https://www.pololu.com/category/131/step-down-voltage-regulators https://www.pololu.com/category/131/step-down-voltage-regula...
