1. When we add a virtual resource with JSON value like { “sp”: [3.14, **null** , 5.68]} the result is converted into an array [3.14, 5.68], where the null value is missing. Is it expected behavior?

Similar issues with dictionaries { “a”: 100, “b”: 21, “c”:null} which will result in { “a”: 100, “b”: 21}

1. Can we connect to DIO3 a relay with coil voltage of 12VDC and current of 123mA?
