Must fight temptation to buy an overpriced raspberry pi

Any photos of the boat and setup?
ATM the boat is being rebuilt inside. Replacing everything.
So the system is in bits. Hidden in the engine bay.
I have old pics of the boat before we regilt all the electrics etc. if it's the shape etc your interested in.
If your a Brit who knows the canals. Think small sprinter but with a flat hull. It's not actually a springer but same steel standards etc.

Like: using the pi to manage your HVAC more efficiently.
Why use a pi instead of a microcontroller?

You are probably right for something like a Pihole, which can easily run on a RPi 3 as well (I think I'm running it on a 3... maybe even a 2.) My fear is something like Jellyfin (which it is not suited for anyway, I know), combined with the fact that my stack of Pis is in my meter cabinet, so a fairly confined space with very little air movement, also passive. Running Jellyfin without transcoding has my Pi 5 running at just under 50 °C.
It's impressive what a gentle breeze will do - if you can get a fan on your cabinet it will help a lot.
I filter my air and positive pressure the cabinet so the dust doesn't build up (as fast).

Why use a pi instead of a microcontroller?
At the HVAC control level it would be a Pico - for the development / maintenance time efficiency: I know how the tools work, I know the community support is there, the hardware is easy to find and available relatively reliably, although ESPHome on the ESP micro-controllers is pretty good too.

my 20 year old pc runs at ~5°C above room temp under load
You really shouldn't be spending your days in a room at 45 °C.

you are joking, but my room actually feels like that.
