Train Smappee to find an Appliance.
Train Smappee to recognise an Appliance. Make sure you have a very quiet consumption with none or very few other Appliances switching On and Off. Otherwise Smappee will be confused while listening to the signature of the Appliance you are switching On and Off on Smappee's demand.
Manual training works best for Lights. But we recommend to let Smappee find the Appliances itself and then provide it to you in the list of discovered Appliances.
