One of my more useful & simple automations is a dog water bowl sensor. It uses an Aqara Water Leak Sensor to monitor when the water dips below a certain level. Then I use Node-RED to get a text and a pushbullet to refill. Keeps our dogs hydrated, especially in this hot summer. Huge points on the WAF scale.
Details: All made for easy disasembly & cleaning. Single core wire extensions to the Aqara allen screw posts. Velcro’d the sensor to a sturdy plastic clip. Twisted the wires through the middle and through tight holes in the orange clamp jaw. Node-RED monitor of the trigger state. When Dry construct a message out to text and pushbullet with email optional. Easy Peasy
I’m curious. How long do you think you can make those cables? I want to use the same mod for our water tank but configure it the other way around. Notify me if the sensor does NOT detect water so I know the water is below a certain level. I could put the sensor in a waterproof housing and have the cables submerged until the water is at low level.
