   <br><br><b>Class METER</b>
-  <li>meter scale<br>
+  <li>meter [scale [export|import]]<br>
     return the meter report for the requested scale.<br>
     Note: protocol V1 does not support the scale parameter, the parameter
     will be ignored and the default scale will be returned.<br>
-    For protocol V2 and higher, scale is supported and depends on the
-    type of the meter (energy, gas or water).<br>
-    The device may not support all scales, see the meterSupported
-    command and its output. If the scale parameter is omitted, the
-    default unit will be reported.<br>
-    Example: For an electric meter, meter 0 will report energy in kWh,
-    meter 2 will report power in W and meter 6 will report current in A
-    (if these scales are supported).<br>
+    For protocol V2 and higher scale can be specified as integer or text, see
+    the output ot the meterSupported command.<br>
+    If the scale parameter is omitted, the default unit will be reported.
+    export/import is only valid for protocol V4 or higher.
