The washing machine tells me how long it's going to take when I start it, but it's often wrong and takes longer. I've been descending into the basement countless times, usually from the first floor, only to notice it's not done yet.
This is just a small thing but I want to share anyways: I just plugged it in a Zigbee plug with power meter and put an entity icon into the default dashboard. It's conditional and only shows up when power!=0.0.
No more pointless stairs!
I have moved it next to the basement temperature but it's not running right now and I don't want to forge the screenshot so it's showing before the change.
I don't have notifications set up yet, but I certainly thought about it!
Edit: "consumption power changes" seems like a weird trigger though since it's changing all the time while running - or is that further detailed and just not visible in the screenshot?
So I did a quick and dirty "when amperage goes over 2 amps and then falls below 2 amps for more than 10 minutes send me a notification" and it's pretty idiot proof.
Idk if you need estimated time to complete, but you can get pretty far with a very light weight automation.
If I were to improve it, I would time the cycle for the wash and add a helper so that I don't get 'washer is done" when I paused it for a shower or something, but that could be a rabbit hole.
This is pretty much what I did.
It's probably consumption power changes below X threshold for some amount of time
