Hello,
I am planing to use these switches ( 1/2/3/4 gang Tuya Zigbee EU Smart Touch Switch Home Automation APP Remote Control Wall Button Work with Alexa Google Home|Smart Remote Control| - AliExpress ) or something like this on my house.
How to configure/connect this to use it as a 2 way switch (2 switches control the same bulb)? Is it supposed to be done by software or by wiring?
