HA on RPi5 shut down

Configuration
1

Hi all together,
my system, HA on RPi5 always shut down and I can’t find out why. The system is installed in my motorhome. The system already installed only view month (May 2024).
On first time I see the problem was in the summer time. Therefore I thought it is to hot inside the motorhome. Therfore I changed the housing of the RPi to a bigger one, but it doesn’t resolve the problem.
Somebody knows the probleme or have a solution to find the fault?

Many thanks in advance for yours help.

Greetings Ug,
Welcome to the forum. Let’s see if I can be of any assistance.

There needs to be a little more information passed along here for us to help you I believe. This I’m predicting is something that has to be fixed in person unless you have some logs showing a problem.

  • IS HA running when it quits, does it restart correctly, ie there anything in the logs?
  • Is it a power supply problem, how are you generating the 5 volts for the PI, is that able to supply 5 amps continuous?
  • Is the power to the PI power supply stable, you battery up to voltage and stable, charging system(s) not giving you E-noise. (Bulbs, heaters and motors don’t care, electronics do…)
  • You mentioned heat, the pi power supply can also overheat and shut down, all those kinds of things.
  • This is a mobile unit, all the wiring tight and not rubbed thru intermittently.
  • ETc…

Hi Sir Goodenough,
thanks for your response and your intention to help

  • Yes, the HA starts correct and in the Log/Protocol I can’t see any problem.
  • I thing so. My motorhome have always more than 13V and 10-14 A. I’ve a seperatly distribution for the 12VDC site for my USB power outlet.
  • I don’t use the pi power supply. I’ve conneted the pi direct to a USB power outlet, that is connected to my 12V power supply.
  • All cables are save, because the distance between 12V power supply an pi is only 30 cm.

That’s your problem right there. A direct usb outlet can only supply 2A of power at most. The pi5 needs 5A, so basically you’re feeding it with less than half the power it needs.

You can even see the under voltage warnings in your screenshot above. Your pi is restarting because it’s not getting enough power.

Hi ShadowFist,
you’re right. I’ve resolved the problem with a seperatly inverter who gives stabiliside 5A.
Until today HA runs permanently.
Only one time HA shut down against. I thing it’s a problem with heat, because I’ve stored the RPI inside a wardrobe, where are also some other technical equipment placed. At moment it is ok, but in the summertime the problem gets again.

If you’re using the official pi5 plastic case, you’ll probably run into heat issues regardless.

There are some decent metal cases which are effectively a huge heat sink. Some models even come with 1 or 2 fans which make a drastic improvement to internal temps on the pi. They’re comparatively cheap if you order from the usual Chinese sites.

I used to run my pi4 in one of these cases. It’s been a few years now, but I seem to remember the temperature dropping by 10-20 degrees.

Note that you might still have to remove it from the wardrobe. If that thing has other equipment and no holes to let heat escape, it’s practically an oven.
