@discuss.tchncs.deWhy not set up backups for the Proxmox VM and be done with it?
Also makes it easy to add offsite backups via the Proxmox Backup Server in the future.
That's for a single one but at tens of MW even a bunch of satellites isn't going to get solar panels to produce an appreciable amount of power.
This video goes into the details of what kind of performance we can expect from the constellation
No the observed power on the ground is on the order of mW/m².
Comparable to moonlight and so far no one has classified that as a weapon.
As always with these revolutionary startups, be careful with what you believe:
EEVblog 1637: Solar Freakin' Space Mirrors! - Reflect Orbital DEBUNKED
At least this one is actually possible and doesn't attempt to defy the laws of physics.
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.
