Did Bambu Lab change something on the A1 recently? (sh.itjust.works)

I have my A1 plugged into a soecial surge protector that provides power to the rest of the outlets if the one trigger outlet draws enough power. So the printer is always on so that I can send stuff to it but doesn't draw a lot of power. When it's heating up and printing the power draw increases enough to trigger the rest of the outlets and a desk lamp turns on so I can see what's being printed better. This is especially helpful at night when the desk lamp is the only light in the small office my printer is in. It's been set up like this for 2 years and it's been great.

This morning I was not actively printing anything and I went into the office and the desk lamp was on. I looked at the printer and it wanted to update the firmware, so I did so. Afterward the lamp stayed on. I rebooted the printer multiple times and while it's rebooting obviously the lamp is off and when it boots back up the lamp stays on.

What is causing this increased power draw? Any ideas or insights?

For now I'm leaving it fully off but I'll have to manually go in and turn it on before sending something to print which is less convenient.

Unless the meassurement in your strip is wrong, I’d guess like you two that something in the FW makes it draw slightly more at idle.

An easy way to test this is to revert to an older FW. Can be done easily in Handy.
If that fixes it, you know it’s the printer. If not, then it’s probably the sensor in your strip.

Good luck!
