Tested the product and it works fine. I have only 2 remarks. The first one is the missing 433Mhz remote, so the product is not complete! And I missed a possibility to connect this product via i.e. a SSR to Arduino or Raspberry. OK, this is a feature not listed in the description, but would be handsome for Home Automation for wired installations.

crabie Where does it say that it comes with a remote? I went and checked the description now because mine did not come with an RF remote either, but I don't remember that it was supposed to. No, still like before, it says in the box is a 4 ch switch and a user manual. it has RF capability built in though, so you can pair is with a basic 433Mhz RF remote, as is the case with other RF compatible Sonoff switches.
If you want to connect your Sonoff switch to a different Smarthome system like Homeassitant and disconnect it from the Sonoff servers in China, most Sonoff switches provides for the option to flash the Sonogg firmware with Tasmoto instead - lots of tutorials on YouTube.
