Hybrid heat pump water heater

One of the reasons that sense under reports is because realistically it only detects the on sign (large draw) then flatlines for an average consumption during that period and the off sign (drop in watts eq or greater than the average consumption probably +/- some threshold).

Realistically the compressor slowly builds over the entire runtime. And the “off” sign is usually confused with other items.

Consider the following. This device is taken from a shelly em reporting to senselink then to sense. This will likely be the best representation of the water heaters actual use. Shelly EM numbers are nearly identical to the EcoNet app.

Compare that to the sense detected device. There is obviously a large portion not detected due to the ramp.

Well for me I think that explanation works a lot better for my refrigerator. For the last few days I’ve had it reporting through a smart plug and through the native detection and they are pretty similar although the refrigerators native detection has a lot more flatlining and is much less erratic. In regards to my Rheem HPWH Sense isn’t even remotely close. It under reports by at least 70%. Maybe I’ll try deleting it and see if it detects it again because I don’t really pay any attention to it regarding the water heater anyway
