Advice on Zero W 2 cooling and powering #857
-
Hello friends, I only very recently stumbled upon this project and I am quite excited to implement it. I have a couple of questions which I hope the community can answer. I am in a 2023 Model Y, UK spec.
Thanks a lot for reading. I know these may seem obvious but I just want confirmation before committing to hardware, and hopefully these haven't been asked before - I did do a search first! |

Hi Jonny,
Its cost me £28 all up so far, so definitely worth playing with - there are other projects using the Pi Zero 2 W to get stats out the CAN bus ports too!. |

I also use a Zero 2 W with a metal case for last couple of years. It can get very hot where I live with summer days with ambient outside temp hitting 112F / 44C. That is only magnified on the inside of the car - you could fry an egg in there and a passively cooled Pi would fare about the same. On the hottest days I use cabin overheat protection which besides not being foolproof will turn the Pi on while the car is roasting hot. One of my Zero's went offline during that so I decided it's better to just pull the plug when I park and it's over 100F/38C outside. I suspect even active cooling will not be enough when the car is that hot. In these temps I use a split config with a standard USB for Sentry and just my music on the teslausb. This way yanking the Pi does not interrupt Sentry. Fortunately we only get these oven-hot days around one month of the year. |
