I have 4 HS300s, 2 KP303s, and 6 KP115s. A total of 36 plug devices. Sense is only recognizing 30. The most recent KP303 is not being recognized. I disconnected Kasa integration and re-enabled it and re-entered all my device info for the old devices but still no recognition of the three new plugs.
What is the real limit on these devices? 30 seems like it for me. Is that for real? My network bandwidth is more than enough. The Kasa app and Hubitat all recognize the plugs instantly. Why won’t Sense?
Send in a support request to support@sense.com. The documented limit is 20 sockets (HS300s count as 6, even if only 3 plugs are in use), but I think there are some trade offs Sense support can make to support more. And as @jonhawkes suggests, KP303s aren’t supported by Sense, because they don’t report power usage.
Is there a limit to the number of smart plugs I can connect to Sense?
The number of smart plugs is limited primarily by Wi-Fi network bandwidth. Typical Sense users can use about 20 smart plugs without issue. Note that each plug of the TP-Link HS300 smart strip counts as 1 smart plug, regardless of status.
ps: I think that the limiting issue might be instantaneous bandwidth. Sense monitor sends out broadcast request for power info, and all smartplugs try to reply immediately. Plus Sense monitor has to process all the responses.
I got tired of waiting for Sense to find everything so I bought 4 power strips that have 6 plugs and 4 single plugs. So far sense can see everything that is plugged in. (I discovered my screens and speakers waste 20 watts while they are “off”. I used the Kasa app to make a button to turn them off with one click. I can also turn things off individually from the Sense app.)
The single plugs help me identify devices. I labeled a single plug Microwave and plugged in the microwave. Then later Microwave and Heater 2 came in at the same time with similar wattage. I renamed Heater 2 as Microwave and removed the smart plug.
