Quick warning these have NO warrantee if you buy from Woot the 2 year warrantee is false advertising. I had a defective smart plug. TP Link support was ready to process the warrantee but could not because Woot is not authorized to sell TP-Link smart home devices. Because I just bought it woot had no problems giving me a full refund. But be aware that the 2 year warrantee is invalid when you buy from woot.
