What to do with my ohm assistant guys

Friends I’ve been using Ohm Assistant for about three years now and despite spending effort on several occasions trying to get it to give me meaningful data, i don’t get any.
Basically while it shows that the consumption has increased (on switching on equipments) it never detects an appliance immediately even if it is in accurate detection. So basically you are left with having to wait for looong after which you are provided with a possible list of things which was possibly switched on.
All this is fine, perhaps teething issues but what explains the zero response to such queries. Can anyone help?
