Our washer and dryer both lack a buzzer which leads to forgotten laundry, and stinky mess that needs to be rewashed. I decided to create a solution by monitoring the washer and dryer myself with some cheap electronics. -As an avid user of Home Assistant, I decided it would be the perfect application to manage the UI and notification system. Now all I needed was a way to monitor the washer and dryer. I tried using sound sensors but found them unreliable. I ended up opting for an accelerometer attached to the back of each appliance. I also added magnetic reed switches on the doors of the washer and dryer to detect if the doors are open or closed. I connected the accelerometers and reed switches to a Moteino. The Moteino is a wireless arduino clone which can perform the logic to figure out which state the appliances are in and wirelessly communicate that data with my Raspberry Pi MQTT gateway. +As an avid user of Home Assistant, I decided it would be the perfect application to manage the UI and notification system.

I also added magnetic reed switches on the doors of the washer and dryer to detect if the doors are open or closed. I connected the accelerometers and reed switches to a [Moteino](https://lowpowerlab.com/moteino/), an arduino clone with an RF transceiver. The Moteino can perform the logic to figure out which state the appliances are in and wirelessly communicate that data with another Moteino that is connected via serial to my Raspberry Pi. The Raspberry Pi reads the serial data and repeats it over MQTT for Home Assistant to use. This is great because I don't have to run Home Assistant on the Raspberry Pi. I can run it on a faster machine and point the [MQTT component](/components/mqtt.html) to my Raspberry Pi. -After taking some sample data from the accelerometers while each appliance was in operation, I was able to plot the data and determine the proper thresholds of when the devices were running or empty. I had to do this in order to get precise ranges so the dryer sensor wouldn't get tripped by the washer or vice versa. In the plot below you can see the acceleration in the x direction for the accelerometer connected to the washing machine. It's easy to see when the washing machine is in operation here. I used the same technique for the dryer's accelerometer. +After taking some sample data from the accelerometers while each appliance was in operation, I decided to plot the data to help determine the proper thresholds of when the devices were running or off.
