Sense detects devices based on their on/off signature. We go into more detail about how device detection works in this blog:
How Does Sense Detect My Devices? - Sense Blog.
I have a Dryer detected via native detection that only picked up the standard run cycle. Energy efficient mode only uses one of the 2 available heating elements, so the waveform looked much different and was not picked up by my default setting. It’s since improved the accuracy, but a majority of the time i run the dryer on standard mode so I don’t see the issue arise too much.
Using Dedicated Circuit Monitoring or Smart plugs that integrate with Sense are a great solution for detection of devices with various types of run settings.
Also, worth noting that we’re looking at how to improve detection of resistive heating elements this year. You can see more of that conversation in the recent Data Science update we shared last month:
