i’m planning to make my home smart and i want to know how can i sense the voltage current i’m using raspberry pi
Are you asking how you can track power consumption? If so, for a single device, or the whole house?

Hello tinkerer
First thanks , i want to use two-way switch for example im outside and i want to know my room lamp on or not and if i turned to off my wife want to make it on by normal switch so im asking about how can i know the voltage current and how can i use two-way switch
You need to use either a Z-Wave switch, or a Z-Wave module behind a manual switch. Those will track the state of the lamp, and allow you to know if it’s on or not, and control it.
If you’re using a manual switch, there’s no way to turn it back on automatically.
