The vehiclePresent device is custom hardware with a Zigbee "radio" and custom driver.
I wrote it some time ago and the system seemed to work. Recently I started working on why there was a delay.
The rule "asks" for an update measurement. and vehiclePresent should be forced to "null" after the asked for measurement was sent.
You will see I'm not a good groovy coder, so my code is likely far from optimum.
/**
* Garage Ultrasonic Sensor
*
* 2020-12-25 - v02b - "saves" in hubitat and can request measurement via device page button.
* able to compare rec'd distance value to threshold
* v02c - add events putting results in db
* v02e - release candidate, still needs testing.
* with v02e everything seems to work.
* v02f - added distance status
* v02g - converted to PresenceSensor due to issues with RM and (bool?) custom attributes
* v02h - Changed the variable echo to echo for clarity.
* v02j - added runin to clear Distance and Presence after 5 minutes (as they could be invalid)
* won't work. We will have to count #OK.
* send @. to make measurement
* v03 - Add variable to count number of measurements made
* v04a - distance was an integer
*
* todo - transfer initial configure to Hub instead of Arduino.
* - add ability to change "ping." in cc2430 and #OK. in Arduino.
* -
* - clean up some of the log commands etc
* Change vehicle present to enum present, not present, null
*
