@bmanos Came across this now and FYI, Custom node names were addressed here : https://github.com/mycontroller-org/mycontroller/issues/464

Not ideal approach - but at least it works

@jkandasa This method no longer works when you set the gateway to use ACK. Is there not a way to set a value for a sensor variable only on the server, without transmitting through the gateway as well.

@jkandasa Thanks. Got it working.

@jkandasa Thanks I have already done those steps. The issue I have is trying to set a value for the virtual sensor via javascript.
What I have done thus far is

1. Create 2 virtual sensors
2. Create a "operation" script - using javascript
3. Create a rule that triggers the script when value changes

I've added my javascript here, but the last 2 lines of code are not setting the virtual sensors values. Can you assist with how to do this please?

// Get Pump sensor via UID-Tag
var tankDistanceSensor = mcApi.uidTag().getByUid("water-tank-distance").getResource();
var tankLitresSensor = mcApi.uidTag().getByUid("water-tank-litres").getResource();
var tankPercentageSensor = mcApi.uidTag().getByUid("water-tank-percentage").getResource();

//get config in variable
tankConfig = mcApi.variable().get("water-tank-config");
fullDistance       = tankConfig.value; // Value 
emptyDistance = tankConfig.value2; // Value 2
totalLitres = tankConfig.value3; // Value 3

//Get sensor values with UID Tags
var pingDistance =  tankDistanceSensor.value; //Water tank level percent

if (pingDistance > 0 && pingDistance < (fullDistance + 50)) {
  percentage =  ((pingDistance - emptyDistance) / (fullDistance - emptyDistance) * 100);
  litres = percentage / 100 * totalLitres;

  //THESE 2 LINES DO NOT SEEM TO SET THE VALUES  
  tankLitresSensor.setValue(litres);
  tankPercentageSensor.setValue(percentage);

}

Hi

I have an ultrasonic distance sensor that sends distances in cm to mycontroller. I would like to add 2 virtual sensors, one for litres and one for percentage and the values for these to be calculated and set/saved when the distance sensor values are received.

I have attempted to do this via a javascript script, but I cannot seem to figure out how to set the values for the virtual sensors.

Please can you let me know how to save a value for a sensor using javascript.

Thanks
