I’ll be honest: this is one of the things I hate about AliExpress. This looks like yet another rebranded tuya switch, which is fine. But they make both a Wi-Fi version and a Zigbee version, not a version that has both that I know of. So which is this specific one, Wi-Fi, or Zigbee?
OK, if it’s Zigbee you are likely to run into an issue that affects all of the Tuya made Zigbee switches, which is that they use a proprietary cluster to handle their multi endpoint devices. So it’s very likely that the first gang will work, but the other two will not.
There is custom Groovy code that people have working with some versions of this device, but each individual reseller can change the firmware somewhat and the existing versions may not work with the one you have. So it can Be a lot of work ahead.
The most recent discussion on this, but for a different brand, is in the following thread. It’s possible that that device handler might work with your switch, but then again it might not. And of course all of this will have to be completely rewritten for the new edge architecture, but at the current time, that does not support multi gang switches.
Ohh!..I’ve been looking for a switch of this brand as well, since I want to install tactile zigbee switches and there are not many brands available, in fact I am looking for a specific one that comes with an integrated outlet but there are not many brands that have it. Except for Livolo, but the Zigbee version of Livolo is not compatible with SmartThings, the BSEED brand seems to be, according to what the Aliexpress seller told me.
Could you comment what was your experience with this switch when you got it?
I created a topic about this asking the same thing as you a few months ago but nobody answered me.
This week I finally got these Bseed zigbee 3 gang and 2 gang switches installed by an electrician.
As I needed for them to just work I also installed a Tuya Zigbee Hub. I then added them in Smartthings via Smartlife.
There are some weird duplications however I got the lights working in automations.
I will try playing around with adding directly to ST when I get a chance.
