My recommendation as someone who has about 30 devices on smart plugs (12 HS110s, and 3 HS300s).
- Highest priority - Use smartplugs on larger usage devices that Sense is going to have difficulty with - I have on my washing machine and furnaces (gas-fired but plugin for the electric).
- Next focus on high usage electronics - PCs, laptops, monitors, bigTVs, plus any other devices you suspect of having greater than 30W of consumption
- Dedicate one HS110 to sampling the remaining electronic and other devices in your house. Look for the ones where you can glean the best long term info.
- Use on modern electronics sparingly - not super useful to individually monitor a device with very low standby and active power (Apple TV = 2W standby, 6W active, cable amplifier varies between 4 and 8W). Given the locations of the HS300s, it’s expeditious to sample all the devices in the given location, but some are less interesting than others.
