  • We have 3 theoretically identical systems here and this same issue occurs on 2 of them. The 3rd one... has bigger issues right now. That would be interesting to see what happens if I swap the Pis around but I'd give it >95% chance the same thing happens.

  • Largely for safety reasons, anytime the system is turned off power is instantly cut to the entire system. All of our CAN devices boot up much faster than the Pi does. Once the Pi boots, it sets up CAN communication.

  • The date/time aspect is an interesting thought. For a bit more context, this machine is a Raspberry Pi connected to several other devices, some via USB and some via a CAN network. The system gets powered on manually, the user performs a task, then shuts it down until they need it again. We only use the date/time for logging. The system is connected to our wifi at our facility but after we ship it then it's likely it will never be connected to the internet except maybe when we're servicing it and updating code. I don't think the Pi has a RTC. I don't really see how the date/time could be causing the issue I'm seeing (seems to be lag in communication with the devices on the CAN network) but I guess stranger things have happened.

  • Trying to reproduce a bug that consistently only shows up the first time we boot up our machines that day. Currently testing to see how long the machine needs to be off in order for the bug to show up again. I'm at an hour now.

  • Hey OP, I'm just starting my self-hosting journey as well. I can program a little bit in Python and C++ but I haven't needed any of that so far. As others have said, some familiarity with Linux would be very helpful. The things I've done so far:

    • Wireguard VPN server on my router(no programming or linux commands, just some config of my router which I was able to do in the router's GUI.
    • Wireguard VPN client on some of my devices. My phone setup was easy, still working on setting that up on my Windows/Ubuntu laptop.
    • Home Assistant on a Raspberry Pi (WIP).

    Eventually I plan to set up a NAS with Immich and some local IP cameras and Plex or something similar.

  • I started drinking diet sodas not long after I was diagnosed with type 1 diabetes but now I prefer the taste of diet coke over regular coke. A lot of diet sodas are pretty bad in my opinion as well. Diet 7up and Sprite zero are pretty good.
