For "I'm done" notification, I use relay with power metering - looking at the power pattern, home assistant can be set up for notification after x time when that graph drops to floor.
Same here. I’m sitting here reading stuff about reporting time remaining and wondering why that matters? Isn’t the concern just when its done?
I got one of these: https://www.amazon.com/dp/B08LN3C7WK . Connected it to my HomeBridge server (all local), set up a push notification using when the energy drops below 5 watts (which happens about 1-2 minutes after the cycle ends).
I setup a power monitor that resets a 5 min timer every time the power usage goes over X. It would still be nice to have an idea of how much time is left - I've considered setting up a pi-camera to OCR the display.
Shelly has a few relays with power metering and they offer lots of local-first and open ways of communicating. I use one to control power to my 3d printer.
