This does not answer your question directly but might help. I'm having the same issues when connected to SmartThings hub. 100w bulb was showing close to 2000W on this outlet. As the outlet has a shutoff when the wattage gets too high (i.e. documentation says 1800W), it often shuts off. Essentially unusable for anything more than a small lamp, and I bought 10 of them. Computer is too much; TV is too much; small appliances are too much. Fortunately I do have lamps I want to use them for around the house, but I'm not sure if I'll use 10... Some seem to have lower cutoff thresholds than others, but all of mine report the wattage absurdly high. I reported it to Monoprice and they offered to let me return them, but didn't know why it was happening or what to do about it. If you or anyone else does find a solution please share!
