at first: this one isn’t wired - it’s WiFi mostly (I guess, you’re talking esp8266). That’s the exact opposite from what you initially stated: wireless and on top it’s 100% DIY - no standards, no “real” vendors and you need a central server, if you’d like to have some kind of automation on it. I don’t recommend this for electrical Installation. I use it also - but for non-critical stuff like christmas lighting or controlling my washing machine state. I’d never would use something like this for the lights/outlets or blinds in my house.
