Dryer notification idea

I'm looking for a small light up button or something I can use so my wife can see when the dryer is done. I'm going to use a vibration sensor. And was thinking of a small led sign but looking for other ideas also

a vibration sensor sends stat every time it detects vibration. in your case, it will chew through batteries in no time.

if you dont need super accuracy, a door sensor will do as seen here https://www.youtube.com/watch?v=x-jIsDXlAeQ

otherwise, an energy monitor plug will do just as well

For energy monitoring I recommend an "appliance module" instead of an ordinary switch plug. Appliance modules are built for a continuous heavy draw. A switch plug isn't designed for long term heavy current draw and will burn out prematurely.

Source: my fridge and a cheap smart plug after about 2 years.

It depends where OP is located, in my case I needed a 220v energy monitor and couldn’t find any on Amazon, so I went the vibration sensors route and made sure to add proper coding/automation so it doesn’t falsely trigger when my laundry is doing a different cycle

It depends, if the vibration sensors is attached to a esp32 you can automate it to wait until 5 mins after las vibration to actually send the notification, that’s how I set it up, I don’t have the light but I get phone + Alexa notifications
