This isn’t so much a vision for the future, as it’s an option right now.

I can’t wait until work puts in car chargers- Top off the battery for free during the day, come home and sell that juice back to the grid, baby!

It may or may not be a string.

If I wanted to access my Jellyfin at home from a smart TV elsewhere, is that possible (securely)? Or would I need something that can run a vpn?

The SD card reader has nothing to do with the serial port, so you’re fine on that point.

I would just try and roll back to the bigtreetech firmware for the 1.3, even if it’s for an older Marlin. Once thats working, build Marlin 2.1, updating the configuration to match the known working one.

I’m imagining a situation where the caller does not want it to be known that they have called emergency. Hostage situations, domestic violence, home intrusions… Last thing you want when you’re hiding in a dark cupboard from an armed stalker is your phone to start blasting at full volume and flashing lights because a well intentioned operator wanted to see through the camera.

It’s a dangerous road to walk for something that would be ‘kind of nice’ in very specific situations.

I want to use Signal. Not everyone else on my contacts list does.

It was much easier to convince people to switch to Signal when you could just say it takes the place of your SMS app. Now it’s just another app to keep track of.
