What kind of tolerance does it have? Does it take into account tolerance stacking and account for being out of tolerance as a whole if stacked tolerances add up to greater than allowed?
True for truly resistive load, like a toaster. If you have motors in your home there is a power factor implication to the calc. Having said that, as long as you don’t need great accuracy then the generation 1 version is a great deal right now.
Nice work! Looks like a very nice product. But wow, it’s expensive, eh? I thought my IoTaWatt was a little on the pricey side…but now I think it was a pretty good deal.
I wrote an integration for IoTaWatt for my Hubitat system, that allows real-time power usage data for each of the 14 channels. If someone wanted to use it on ST, it would be an easy software port.
