Raspberry Pi, powersupply

Hello

How did you power your raspberry pi's? As you should not just cut power off, I was looking for a powersupply with a little battery to allow it to perform a clean shutdown. Sadly i have not found anything usefull.

How did you solve it?

I have that installed already, thats a good way of doing it. But my Venus has no display, as i use HomeAssistant to control the functions.

Therefore a HW solution would preferable.

Hi,

I use the "strompi" HAT for this. As I was not able to get the config program running under Venus OS, I used an other Pi to program the HAT.

I do not know if it is allowed to put external links into posts, so please just search for "strompi" in Google or Bing to see if it fits your needs.

I have a small 5v 1A switch mode regulator that connects to the main storage battery (26Vinput). The pi then draws about 100mA from the main battery bus, (also with 2 x VE direct usb, 1 x rs485/usb and 1xMk2)this is 5 small components on a pcb. There is a diode and switch as well. This has been working fine for over a year. I have never had any issues relating to just 'cutting' the power, and only a few hangs when powering up. This pi stays on all the time. (The power is also fed to the pi via the 40 pin header, not through the 'official' power connector - I found it impossible to source a re-wireable plug for this.

I routinely just turn off the power to my PI and have never had an issue.
