My LG does picture frame looking pictures it came with (never connected to internet).

They seemed to have thought the brightest white of the sun would be the best choice.

Nighttime does not exist if you turn on the TV and the Shield is sleeping.

Set of cron jobs that check services, then send a Matrix message if there’s an issue.

For the cron jobs, I pipe stderr to another script that watches those and does the same.

If all fails, and internet is unavailable and the router crashes, a Pi will toggle a relay, cutting and resupplying power.
