Smart Stackable Power Meter (Main Unit)

I have been able to use this on my project. It provides what I need to control and monitor the device consumption connected to this product using the API.

So this module by it’s own total useless. It only converts serial communication to ethernet lan or wifi. Of course without this, 4 stack relay can’t really do mutch. It functions like a light switch. So it we are talking of automation, you have to get one of this.
