Problems detecting appliances

Hi.my sense has problems detecting my appliances,so far it worked on the water heater after 4 attempts, the fridges the stove and top stove are 50% discovered …dryer was found but comes on in the same bubble as my keurig,and the stove as the water heater …my LG TV was found then it disappeared…so slowly for me …at least I know how much usage i have at the end of month .
