I did something similar except I used a vibration sensor since we have shared laundry for the floor. When doing laundry we take the sensor and then stick it, using the magnets glued to the back, onto the dryer/washer. The distance drops the signal strength of the sensor which is what tells the automation that clothes washing/drying is in progress. Once vibration has stopped it knows that the laundry is done. Alexa then loudly notifies us of it (great fun if it happens in the middle of an interview) and the e-paper display in the living room shows an alert so we don't forget.
- yjftsjthsd-h 3y agoIs that a product you bought or something you made yourself? I've been wanting something like that but haven't figured out how to get it
- marcinzm 3y agoI used a YoLink vibration sensor. The lack of a local mode for YoLink is a big negative but there's also Zigbee vibrations sensors. The positive is that in my experience YoLink has been very reliable across the board while Zigbee has been hit or miss. Also unlike other cloud based services (ie: Kasa for example) they provide a MQTT integration so there's very low latency.
- yjftsjthsd-h 3y agoThanks; I actually do prefer zigbee, but that tells me what I'm looking for
- pengaru 3y agosmart, you could probably do the same thing with a cheap piezoelectric microphone / transducer (actually I wouldn't be surprised if a vibration sensor is basically just that) plugged into an audio line-in port on an RPi running the show.
