+Python only loads modules once, so domoticz will only load a module the first time it is needed. Code changes will not be reflected, only after a restart of domoticz. Note that doesn't hold for scripts, they always get reloaded.
+To have your module reloaded, you can enter the following code in it.
+import reloader
+reloader.auto_reload(__name__)
