🧺🔔 Homebridge Laundry Present Sensor

This is a Homebridge plugin that notifies about the finished laundry.

🧰 Installation

First, you need to purchase a Zigbee2MQTT compatible smart plug. I've purchased this one.

When you purchase please take a look at maximum load. Mine has 3680 W. Then you need to setup the Homebridge Zigbee2MQTT plugin and make sure your smart plug is visible in Home app. After confirming it, you can install this plugin. When it comes to configuration, you can leave the default values for "Base topic" and "Server" if you installed your MQTT server on the same device as your Homebridge instance. Add your IEEE addresses of your devices to the "Devices" list. You can get them by looking at your Smart Plug serial number (it should start with "0x"). After that, you're ready to go!

⚙️ How it works?

The plugin creates a occupancy sensor which would be used to notify you about the finished laundry. This plugin monitors the power draw of the appliance connected to the smart plug and if there was any power draw in the past and for two minutes there isn't any it turns on the occupancy sensor and disables it after 30 seconds.

The reason behind waiting for 2 minutes is laundry machine power draw does not equals 0 during its work.

📝 Additional notes

This plugin could be used with other appliances than washing machine such as dishwashers - basically every appliance that is not so smart, and you would like to get a notification when it finish its work.
