On this page: Configuring Power Channels (CTs) — IoTaWatt 02_03_20 documentation
you give an example name of “Living Room” that is rejected as “invalid name” by
my IoTaWatt (Firmware version: 02_07_05). The unit appears to reject spaces and non-alphanumeric characters in names. It does allow an underscore, and I do wish that other characters were permitted, but please fix the documentation to match the actually accepted character set. (And please document what that character set is so we know what and how many characters are permitted.)
