     powerMap will help to determine current power consumption and calculates
     energy consumption either when power changes or within regular interval.<br>
     These new values may be used to collect energy consumption for devices w/o
     power meter (e.g. fridge, lighting or FHEM server) and for further processing
-    using module <a href="#ElectricityCalculator">ElectricityCalculator</a>.
+    using module <a href="#ElectricityCalculator">ElectricityCalculator</a>.<br>
+    Note: As this module will derive some additional readings when readings are changed 
+    (with event) in the supervised FHEM devices to prepare for further processing with
+    other event handlers, this will happen on a rather early stage of the entire event 
+    processing. So do not expect powerMap to work properly when setting own values 
+    (e.g. using notify or DOIF in combination with "setreading" commands).
