ultrasonic sensor(s) in Nixie, questions, suggestion

Hi Folks

I have a standard hc-sr04 sensor, actually I have 2, but looking in Nixie, ultrasonic.py in services, I don't see a way of actually activating 2 individual sensors.

what is the correct way of testing this sensor to make sure it works? 

 

In the ultrasonic.py there is a print statement: print "ultrasonicSensor test is ", i01.getUltrasonicSensorDistance(), however, I have not found where this is printed.

 

In the webgui, on the ultrasonic page, there are entries for Port, Rate, data bits, stop bits. parity,

pretty sure those don't pertain to a hc-sr04.

 

Is it possible to have in future releases, a button "TEST", that when pressed would execute a single range measurement?
