Wouldn’t it be nice to know if your dog’s water bowl is empty? Let us build a sensor that measures the water level every 5 minutes. This value is sent to MQTT server and Home Assistant automation takes care of the rest.
This sensor connects to MQTT and Home Assistant. See dogsensor.yaml for adding this to HA. Assumes that one has set up various notification sensors available in HA.
Things needed:
- 3D Printed Case
- 18650 Battery
- ESP8266 12E
- Rain Water Level Sensor
- Arduino Code
