    A great alternative to the ZMAi-90, especially since the latter has started shipping with ARM-based MCUs. As of July 2021 the DDS238-2WiFi is shipping with an easily Tasmotised TYWE3S module. The only downside is that both top terminals are Neutral while the bottom terminals are Live in and out of the beefy 80A bistable relay.

    I put it on the board of the house. Connectivity is pretty good, but it's gotta be close to the router because it doesn't have very much range. In consumption readings it seems to count well after some tests I've done, but I haven't compared it to the provider's meter. It also gives you the ability to break the circuit if you put it in the water heater, for example.

    This one combines power and current measurement as well as a remote on/off controller. I have not installed it yet but it's quite promising.

    Great product. Supports the whole house and does the job. The chip inside is ESP so if you have the skills you can flash it with ESPHome or Tasmota if you want it only local. So far it handled loads up to 25A so I guess the rating is correct. I believe it measures with a clamp rather than directly, that's why it can handle those loads. Nevertheless, for the month or so I have it, it works nicely!

    Satisfactory packaging. Fast shipping (after the time, which had been announced as long... and was! So normal and ok, on this side). Not yet installed and tested

    Tested the item. Works well. a pity the forward and reverse power quantity cannot be reset. The WiFi app also does not display all registers.

    Good WIFI switches that I'm using with Tuya android app. Easy to install and link with app. Breaker seems good quality and well made.
