I’m a technician but new to ST and ZigBee,
I use several Smart Life ZigBee Power switches. 1gang and 2gang work well, but for the 3gang switch I get only 2 controls and I do not know to add a 2nd child device to control the 3rd gang.
App - add device - start connection on switch - fails but it appears as “Thing” in the device list. Then change the Type to “ZigBee Switch Power” for the 1gang and “ZigBee Multi Switch” for 2gang - everything is find. But for the 3gang I get only ONE child control so I can only control 2 of the 3 switches.
The child has the same ntwork id suffixed by :02
I tried to manually add a child device with suffix :03 or :04 but it does not help.
Hopefully someone more familiar with that brand will be able to help you.
Meanwhile, A small note on the Terminology, just to make sure we’re all talking about the same thing.
I believe you are referring to a “three gang“ switch, not a “three-way“ switch.
A three way switch is when two switches control the same light fixture. For example, this is quite common for a staircase, where there will be one switch at the top of the stairs and one switch at the bottom of the stairs but they both turn on the same light.
Also, The first rule of home automation applies, particularly for multi gang switches. That is, “the model number matters.“
“Smart Life” Normally refers to an app which is used by many different brands. I’m not aware of a 3 gang light switch that is branded “smart life” although there may be one. Some of the brands that use the smart life app include Moes, Suzixcen, Mnycxen, Benexmart, zemismart, Nedis Smartlife, Globe Lighting, and many more. Many of these are rebranded Tuya switches, but may have different firmware which can affect the behavior of the switch.
What’s the exact brand and model of the switch that you have?
Zemismart is part of the Tuya ecosystem. The problem is that Tuya makes a slight change and gives the product a new fingerprint. So you might need to get @Mariano_Colmenarejo to add your finger print to his driver to make it work. He is very good about helping people out.
If you install the switch and it doesn’t work with the recommended or stock drivers install the API Browser+. With the API Browser+ you can get the fingerprints. Send a screenshot of the read out to Mariano so he can add the fingerprints.
