I have a simple ESP32 board with two ultrasonic sensors mounted on the ceiling of my garage. The sensors are pointed at my cars as a presence sensor for when a car is Home or Away. Since the Ultrasonic sensor returns distance I used a Threshold Sensor to determine Home and Away.
The problem is the vehicles show as Home or Unknown, but never shows Away.
I’ve read several posts and it seems obvious I have an incomplete configuration but hoping someone can explain where.
My Threshold Sensor is configured as
- Hysteresis: Not Defined
- Lower limit: Not Defined
- Upper limit: 1.6
- Show As: Presence
Here are screenshots.
Thanks in advance!
