What if I don’t have an analog expander?
Can I do the same with Syrus 4 or a NON syrus device?
If possible. There are other fields that can be used for this same purpose:
Although the following fields are specific to the analog expander, third-party equipment may use them if they have multiple analog inputs.
an_in1, an_in2, an_in3, an_in4, an_in5, an_in6, an_in7, an_in8
an_fdiff_in1_in2
an_fdiff_in3_in4
an_fdiff_in5_in6
an_fdiff_in7_in8
Fields used by Syrus 4
an_in1, an_in2, an_in3

This is a payload example used for Syrus 4:
