RGBW2 for 90W+ lights

    Basically I have a large monochrome LED strip, measuring about 190W in total. Of course, Shelly RGBW2 can only provide 90W per channel, so I've solved this by adding 30A RGBW amplifier from Aliexpress (this one to be exact). Sadly, the web interface shows that power consumption is zero watts :( Is there a possibility to somehow connect all channels in order to receive correct power usage? :/

    Absolutely correct!

    With this device, the power consumption bypasses Shelly.

    For a possible solution (?): I don't know if it is possible to parallel Shelly's four outputs (R / G / B / W), use it as a blank, and use all four channels together in a group (?).

    I think it's a problem if you manage any of the four channels independently, and I don't know what can happen.
