    As measurements it is very good. But the bad thing is that if you connect it through a relay to work as a voltage monitor, when it gives an error if the grid voltage is high or low, it does not reset automatically when the grid returns to stable voltage. You have to reset it yourself either remotely through the eWeLink app or, if you are near the panel, from the button on the device

    Excellent, it does exactly what it should with easy connection and user-friendly app. It comes with a base and screws for on-field installation!

    Very positive surprise at the quality of the device in relation to its cost.
    It works perfectly and measures the consumption of a 10kw heat pump via the clamp meter.

    The automation for activation and deactivation has not been used, but it also seems satisfactory.

    Perfect for my needs. It seems to be of good quality like all the Sonoff products I own. I like the fact that it has a clamp ammeter with a clip, so you don't have to mess with removing the phase wires. The wifi is strong, and I didn't even bother with the provided antenna for my panel because it has full signal without it. The display and the app show real-time voltage/amperes/watts and kilowatt-hours. It also keeps consumption history for 6 months, and with the app, you can download a CSV file of the history. It connects to HomeAssistant as long as you connect the ewelink add-on.
