Original Summary

Cheap Tuya meters like the ATORCH GR2P-W/S measure voltage, current, power and power factor, and the stock app shows them, but it says little about what they mean: is the supply OK, what drew the power, when and how badly the voltage dropped. Power Trace keeps every reading on your own computer or Raspberry Pi and explains what's going on: - voltage sags and spikes: how often, how deep, how long; - when big appliances switch on and how much energy they use; - your bill at your own tariff, including two-rate tariffs; - a Health Score from 0 to 100 with an explanation of what pulls it down. Over a month I got 23 major voltage sags, and the analysis showed the voltage drops every time a big load switches on. Next step: checking the wiring. Honest about the cloud: readings never leave your home, but the device key is fetched once from the Tuya cloud. The easiest way is a QR code in Smart Life, no developer account needed. Windows and Raspberry Pi / Debian, free for personal use. I'm the author. Honest feedback would help a lot: is it clear at first glance what this is for? And what would stop you from trying it? getpowertrace.com   submitted by   /u/Power_Trace_2908 [link]   [comments]
