Six months of use and nine devices detected. Reports for only 2 - the 10 year old Viking Kitchen disposal and 15 year old GE water heater - are complete or reliable.
Most detected devices are partial or not reliable. For example, Sense detects the Fridge door being opened (lights on), but not the compressor. The fridge ice maker was miss-identified, but corrected. The clothes washer and dryer are partially detected, heat only, no motors. Sense reports the TV is on, but miss reports the TV as turning off while still on.
The GE water heater was recently replaced with a similar model, but Sense does not yet recognize. Sense found my Heat Pump AC, but not the Heat Pump heater. Nor has it detected the Air Handler. It detected a hair dryer, but does not reliably report on/off. Sense found a vacuum a few months ago, but has not seen it sense. It does not recognize my vacuums in regular use.
I added a pair of TP-Link outlets which helps measuring the dishwasher and home server.
I understand the limitations. I’m patiently waiting for and hoping that Sense will one day provide full, consistent and reliable info on my biggest individual energy users such as Pool pump, AC/Heat/Blower, Water heater, Oven/Stove, Laundry. Nice-to-haves for me include aggregate lighting use, Ceiling fans, vampires (Tivo, Apple TV, Stereo, IoT). Network device discovery is on.
I’ve opened cases on several of the device issues.
