A friend makes game cabinets for casinos and they have a 100% uptime requirement from some customers. And they use odroids for that. And a casino cabinet has more sensors than I ever though possible.

Edit. With that said the machine in the elevator does not need to have 100% uptime a restart is fine, the security systems and locks are controlled by other systems that are not connectied to the carriage in the hoist way.

The computer in the elevator just places floor calls on another system over a bacnet connection. So it handles media and floor calls.

Edit2. Source misspent youth. I can recommend https://www.youtube.com/watch?v=oHf1vD5_b5I and there is one more I can’t find right now.

There is 2 things to this, its cheaper to buy hardware like a raspberry pi or similar with 8gb of ram and use that to build the elevator. And it might genuinely easier to source the parts and future spare parts.

But as a developer I want to be snarky and say why does a elevator need 8GB, it should have 256MB and use 168 MB max where 100 MB is display graphics and music, 5 is the control system with 3 copies of the variable for redundancy and the rest is telemetry and a memory leak that eats 1MB every 2 weeks because someone is resizing the audio buffer for floor announcements everytime.

But its probably just a mini pc that’s using 512Mb all in all running some linux distro. and the 8GB is just not being used.
