Hi all, thought Iād share a little project that I made over the weekend. I always forget to fill up the water reservoir in my Tassimo coffee maker so I added a sensor using a Xiaomi Mijia Aqara Water sensor but in reverse so the detection is the lack of water as opposed to the detection of water.
I fitted this using copper tape (conductive) to the reservoir just above the minimum water line and have it integrated using Zigbee2MQTT.
Hope this will inspire others
