One more word of advice. Since the limit is a per used plug limit, don’t feel compelled to fill every plug in an HS300 or to put a HS110 on every device you don’t think Sense will “find”. I was compulsive in my usage and accidentally went over the limit - Sense helped me reminisce the issues that ensued.
But looking at the results, I should have been more judicious in application of smartplugs. Some, like my Apple TV’s and TiVo Mini use very little power in both standby and in active mode. Others, like my switches and router bounce around a little bit are essentially constant users around their average operating power. So one suggestion would be to use/name one HS110 as the sampling smart plug so you can look at the history of each device of interest over time, to see if which use patterns are worth monitoring.
