Finally

I don't know what you guys did but from the last 2 weeks the units have been working as advertised.
some features still missing like sharing but they are minor compared to the non-connection flaws experienced in first 6 months this year.
Thank you for updating the firmware or software. It's now a viable option to install as a smart DB controller.

hello, to be honest I am satisfied with the build quality, but the software part is not satisfacence, in addition to being not very detailed the energy consumption part in the app, it is not supported by the ewelink dashboard, this is serious, your most expensive product has the most approximate software, it is not possible for example to see the total consumption of all 4 channels but you need to see each one separately, also the app displays the mail controller and the relay but with duplicate information, I don't know what sense all this makes .
Mine is a criticism only to explain to you what are the things that I think should be implemented immediately, otherwise it makes no sense to buy this product instead of having 4 pow 3 that have the same function, at least if there is a fault on the device it does not stop everything the plant

No features as per other Sonoff items.

No auto power on settings.
No sharing settings
No scene settings.

Simply put this product was released prior to being finished. I expected it to have same functionality as other Sonoff products which I love.

Apart from being a bulky addition to the DB it's functionality does not deliver enough benefits to substantiate purchase and installation costs.

Good but has substantial gap

Yes, it is a nice design and appears very good. The very big gap is that, IS NOT POSSIBLE TO MEASURE THE TOTAL ENERGY. It could be even better if the MAIN PART should allow metering of the total supply and support the current for up to 100A.The main part should replace the utility single phase meter.

surprice

unfortunately this beautiful device is not supported by the ewelink web dashboard, in the app it is seen as a double device, for no reason, it is not even possible to see the total energy absorption of the 4 channels but only individually
