Home Assistant is indeed quite nice and relatively simple to set up with the Docker images provided by the team. Device setup on iOS was a little inconsistent, but has been rock solid for over a year. Check out Homebridge as well. I run both.
I ought to take a break from my Docker Compose work and get back to migrating off Homekit and into Home Assistant. The Home Assistant Yellow has been a real champ thus far, and once it’s set I can then tie the Unfolded Circle 3 into it for better control.
What value do you get out of Home Assistant you don't from HomeBridge? I use HomeBridge for a few devices, my Windmill AC, some Govee lights, and previously my Ikea smart lights (Tradfri, but now Dirigera supports HomeKit).
They have access to guns, stingrays and flock cameras. They tap every email, message and phone call you make. You wouldn't even know if you are subject to warrantless surveillance as it might be illegal to tell you under the patriot act.
I'm pretty sure being able to access an Airtag that was put into stolen mode by the owner is the least of your concern. I'm not even sure what failure mode you are worried about because you didn't elaborate.
Please don't think I'm trying to be all high and mighty because I live in the UK and am surveilled even worse than you are (although at least our police are very rarely armed).
Perhaps a CSF leak due to a dural sack tear in the spine? Was his symptom only having headaches while standing? Happened to my wife. 6 weeks of absolute hell.
On second thought — the opposite. A bulge/blockage of CSF?
Apparently, as I've recently learned due to a debilitating headache, CSF pressure (both high and low) can cause a whole host of symptoms, ranging from mild headache and blurred vision to coma and death.
It's pretty wild that a doctor wouldn't have that as a hypothesis.
