Question about JSON request and devicevalue

[wkrasner]

I wrote an app for ESP32 Arduino which uses the json request : json?request=controldevicebyvalue&ref=2755&value="+ voltage_value;

The value posts a decimal to the device correctly as below.
When I pull the devicevalue through vbscript I only get the integer value (4) and not the 3.64

I am using hs.DeviceValue(2755)

Any thoughts:

You should be using hs.DeviceValueEx(2755) which returns a double.

hs.DeviceValue(2755) will return an Integer.

Thanks. I did try that and it returns the integer 4 not the decimal 3.64. Any thoughts. BTW 2755 is a child of the device

hs.DeviceValueEx(2755) is the correct scripting command to use. Try a simple script to read this in the hs log.

Great Idea. Ill try that. TY

As it turns out. I was using the json request to store a control value (change the state of the device), that has to be an integer. I looked in the json documentation and it does not appear a manner in which to change the device value , but rather the device state. So i did a work around by creating a range of values 0 to 25000 and simply changed the state from the arduino IDE sketch by using the product of the decimalized volatage and 1000 and then I convert back to decimal by dividing by a 1000 on the other end. Crude but works.

You can set a device value via JSON but I'm not sure its documented correctly:

JSON?request=setdevicestatus&ref=2755&value="+ voltage_value;

Thanks ill give that a try
