I have a unused RPi4 (the 8Gig one) running DietPi. I did use it as a playground but ever since I am renting a Hetzner machine for (playground) stuff that I want web accessible, I don’t have particular use for the Pi.
I am currently running (outdated) Home Assistant on it but there isn’t much I can connect it with (yet, getting the flashable/compatible ikea smart lightning zigbee? bridge thingy is on my bucket list). Obviously I do have a pihole there.
Shoot me any other ideas I could run there. Some kind of monitoring of my rented infra would be cool (I already have uptime kuma on the dedi hetzner box). One idea I had was if there are some OSS security scanning “daemons” I could use on to monitor my other infra.
Thanks a lot!
I’ve been wanting to use multiple raspberry pi zero w with sensory hats to feed data to a central home monitoring system. Would be a fun project.
It is! Especially if you want to write the code yourself. It’s an interesting design problem if you start to consider cases where the PI may be offline (mobile on a battery in my case). Do you lose that data? Store and forward? In memory or to a local data store? It’s a fun rainy-weekend project.
Word of caution - HATs can be a rather inaccurate in their temperature monitoring. The Pi gets warm. I had done my work using a PTC thermistor that was distanced from the Pi itself. I’ve got a friend using a HAT and it’s been very off (up to 10C above ambient!). A Pi Zero may not give off as much heat as, say a Pi4 though. YMMV.
