Can we please have a standby mode?
My printer lives in a living space. I also want it to be available via connect whenever I want to print to it. However in standby with the chamber dimmed it's still very bright.
Can we please have a standby mode option that turns off the chamber lights, light bar and screen after X hours of not being in use? I imagine any interaction with the controls, door or connect would wake it up again.

I use a switchable smart power plug (Shelly Plug S, any will do), so I can turn the printer on and off remotely. This also uses less power than any standby mode possible with that beefy Core One power supply.
Integrating with Home Assistant for example, you could even monitor nozzle temperature and prevent power off if still too warm after a print, the possibilities are endless...
That's a recipe for trouble. Any standby period is just time for the filament to absorb moisture and spoil - ordinarily you should unload the printer when removing the print from the bed and put the spool in a dryer. Then when you're ready to print again you should load fresh, dry filament and start at once ...
I consider Prusa's pandering to requests for remote printing to be a great mistake; the sort of users dumb enough to try it are also likely to be the loudest complainers about the resulting low quality prints.
Cheerio,

Thanks for your concern but I print from a drybox anyway. I find filament can sit out in my fairly dry environment for a couple of weeks without noticing any print quality differences.
Even if the printer is unloaded, I'd like it to still be in standby and on the network so I can upload files as I design them.

I use tasmota sockets all over the house and for the printers I put a widget on my phone screen using the Android-App "HTTP Request Shortcuts". That way I can switch my Prusa on and off using my phone (or the physical button at the socket, or the WebUI, or HomeAssistant, ...). Maybe that could be a solution for you, too.

RE: Can we please have a standby mode?
Thanks, that issue seems to cover pretty much everything I asked for here, chamber and LCD dimming. I do also run Home Assistant and have some spare smart plugs, so will look at setting that up in the meantime.
RE: Can we please have a standby mode?
I just noticed another aspect of a real standby mode: After printing, the motors stay "on", i.e. they make some noise. After turning them off in the menu, the printer is truly silent and power consumption went down ca. 3.9W.
I guess that's a remnant from MK4 printers where they "hold the gantry in place"? On Core One, the head cannot sag, and the build plate should not sag by gravity alone due to the flat screw angle of the rods?
