  • This switch is the 2CH variant of the Gerier WiFi Switch series. It is really a small device...

    Start the teardown by turning the device so that you have the back on top. Use a small knife to open it from any side. Just in the middle of each side you can push a small knife in and open the case without destroying it. After opening the case backside take of the PCB by pressing on the green wire screwbar.

    The device uses the CB2S Module. Well - all connectors are easy to solder and even documented on the PCB. Just the CEN you need "somehow" to connect a creativ way. I used tome measurement connector as you can see in picture. After connecting everything necessary for flashing, just start the usual procedure.

    Welcome - many thanks for your efforts on OpenBeken and publishing it freely on the Internet. My way to say thank you for this...

    More teardowns will come in the next days. Will write something about Gerier 1CH Switch, Gerier Garage Door Open Unit, and CurrySmarter Gen6 Jalousie/Shutter switch. Need time to take pictures and write some warm words about.

    Comments on improvement for posts very much welcome...

    Thank you. If you want to help more, the first thing to watch for is filling all the fields in the template. I always do it by hand but I am just one person and it takes hours already. We are at 517 or so teardowns at the moment, that's a lot.

    Please post any teardowns you can get, as detailed as you can get, with all possible fields in template filled. I am also actively making new teardowns:
    Several boxes of smart home modules on a wooden table.
