Makes me very glad that my printer has a power supply with a big clicky hard-cutoff switch that only gets turned on when I intend to use it.
You don't even need a pi for this option. I'm running octoprint off an old android phone and it works great.
Yeah but now you have a smart plug in your house.
Is the smart plug company going to turn it on in the middle of the night? You've just moved the problem from one closed, proprietary technology to a different closed, proprietary technology.
Not all smart plugs are proprietary. You could even make one yourself with an ESP-01, a relay, and open-source firmware like ESP Home if you know what you're doing to make it safe at that kind of voltage. If you're overconfident in your ability to make it safe, then you've still got an untrustworthy smart plug at the end of the process, so it's not necessarily a good idea, but it's not proprietary.
Hmm that's a good point. Never seen one for sale that I trusted though, and I did have a good look at one point.
There are many that can be reflashed with open source Tasmota firmware. Sonoff is one of the popular ones.
IKEAs Trådfri plug can be adopted into anything that supports Zigbee. Works out of the box with Zigbee2MQTT. No flashing required.
Don't use wifi smart stuff. My house uses zigbee, so you have to be physically close to interact in any way. That really narrows down bad actors.
I've got my smart plugs on Zigbee, through Home Assistant, so they're not on the cloud. But that did require some research so I could get the right devices, because it's a bit of a minefield trying to find smart devices that don't need to be cloud based.
These printers come with that too. Just most didn't have it turned off overnight when this happened.
They should have it turned off because the Bambu lab printed have been tested and shown to draw much more power when idle compared to other printers. It's not much but overtime it adds up.
Same :)
