@@ -26,6 +26,8 @@ In commands with `x..y` value parameters use a number from `x` to `y` range.
 
 When a command mentions resetting to *"firmware default"* it means the setting will revert to the one in the flashed binary file. If you used `user_config_override.h` at compile time it will revert to those.
 
+If a command name is prefixed with `_` (underscore), the command result will neither be logged nor published via MQTT. However, output from the `Status` command will not be suppressed, as it does not count as "result". This is also the case where command output is only asynchroneously generated after some time, like the `Ping` command.
+
 !!! note
     All commands are standard in the form: `COMMAND`<`INDEX`> `DATA` It has only one `SPACE` between `INDEX` and `DATA`. (There is no command in Tasmota that allows the `=` sign)
