For those of you monitoring analog inputs, do you do any "sanity checking" on your value before displaying it (or using it in Node-RED)? Please do.
A couple reasons why:
1) the way we represent a "not a number" value (typically 0x7FFF FFFF in current hardware) will vary depending on the software you’re using. And the groov gadget/version.
2) Sanity checking is especially important if you're doing any math like totalizing on the value or visualization (like a trend).
