Additional information regarding Home Assistant:
The sun component (which should be enabled by default) already computes the sun position for you.
Elevation and azimuth are available as standalone sensors sensor.sun_solar_azimuth (might be disabled by default) or as attributes on the sun.sun entity.
Not an expert but these systems are fairly self-contained and robust. A few things that can be checked easily is that the fan spins, the radiator is free of debris and some compressors might have a sight glass for the oil level.
Any other checks regarding performance of the system, leaks and refrigerant level require you to perform a full refrigerant discharge and recharge. That takes special equipment and some time so no one in their right mind would do that for free, unless they can then force/guide you into some kind of upsell situation.
Larger systems might have some kind of oil filter/catch-can that you might be able to check easily but I’m not too sure on that.
After all heat pumps are just plain old A/C units with a reversible cycle.
I don’t have any experience with it but this might do something along those lines(?):

Seems like you can just add it to one or more of your existing esphome devices.
Und an dem Punkt könnte man die Routen und Fahrzeiten dieser Fahrzeugverbände zentral steuern, damit sie immer grüne Welle haben.
Dieses Werk könnte man zB ein Stell-Center nennen.
The 44.1% battery failure figure is regarding the “starter” battery (12V) and is combined from all vehicles in the study (EV and ICE).
The HV Battery for the traction drive is grouped together with any kind of motor failure and comes in at 22.8 %. But this figure also includes ICE vehicles ejecting piston rods etc.
The only EV vs ICE numbers stated directly are the total breakdowns per 1000 vehicles at 1.9 (EV) and 3.6 (ICE).
I’d be really interested in a chart showing the failure categories separated by EV and ICE.

Out of curiosity I’ve let it rate Low<-Tech Magazine, a website run on an ARM SBC powered exclusively with off-grid solar power, and that only achieves 87% / A.

You can use their online web-editor (similar to OverLeaf for LaTeX) or download the open-source engine and run it locally (there are extensions available for many text editors).
Compared to LaTeX I find it much more comfortable to work with. It comes with sane, modern defaults and doesn’t need any plugins just to generate a (localized) bibliography or include links.
Since Typst is very young compared to LaTeX I’m sure that there are numerous docs / workflows that can’t be reproduced at the moment but if you don’t need some special feature I’d recommend giving it a shot.
Seeing these little IT gems all over Lemmy always makes me smirk :)
