So I have a suggestion:\r\n\r\nI recently used a GY-906 MLX90614 non-contact IR temperature sensor, connected to a D1 Mini to measure the temperature of the exhaust stack on my gas water heater as a way to measure how long the heater is running.\r\n\r\nI could have used a temperature probe but I wanted to see how the MLX90614 worked.  It works great and sends the temperature as an MQTT value back to HA every 15 seconds.  I don't care what the actual temperature is, I just want to know when the burner is going, and when it stops, so I have it mounted about two feet from the exhaust stack.\r\n\r\nIt works so good that I bought another sensor and am going to again wire it to a D1 Mini and mount it on top of my desktop PC monitor to detect when I am sitting in front of my PC so as to keep the room light on.  Again, the actual temperature is not important, only an instant noticeable rise above room temperature.\r\n\r\nSo, to finally get to my point -- one of these sensors could be mounted behind your sink and detect when someone is standing in front of the sink.  What makes it so simple is that it only requires 3 items: the GY-906 module, a D1 Mini, and a 5vdc microUSB power supply, and is programmed with ESPHome.  No other support components are needed since the GY-906 module has an I2C interface.\r\n\r\n[https://www.amazon.com/MLX90614ESF-Non-Contact-Infrared-Temperature-Arduino/dp/B07YZVDWWB](https://www.amazon.com/MLX90614ESF-Non-Contact-Infrared-Temperature-Arduino/dp/B07YZVDWWB)","subreddit_name":"homeassistant","author":"Dansk72"},{"body":"Just yesterday I put together a little temperature sensor that only requires a  **Wemos D1 board** and a **MLX90614 IR temperature sensor**.
