SONOFF IW100/IW101 - 美國版 Wi-Fi 智慧型電源監控牆內插座與開關

I’ve been using this for about three weeks and the power metering feature is the real deal, exporting the usage data to a table is surprisingly easy. Setup in the wall box took me a little longer than a standard switch, but once it was in, everything worked smoothly. Glad I picked it up for tracking

The overload protection kicked in the first week when my space heater and microwave shared a circuit, and it cut power instantly before tripping the breaker. Getting the CSV export to work took about a minute on my phone, and it's nice to see the actual wattage instead of guessing.

The power metering is what sold me, and the data table export works exactly as described. I can finally see what my old fridge is actually costing me each month, and the overload protection is a nice safety net. Setup took maybe 15 minutes, and it’s been rock solid since.
