I am designing and building my own house. I am very interested in automatizing several devices as blinders and lights.

In general, I am thinking in using Zigbee (Xiaomi and Aqara), RF and IR devices. The latter two will be controlled by a RF + IR controller.

Each device itself won't probably consume too much. However, imagine all my switches are connected and my blinders are always waiting for an RF signal to activate them. All those devices needs then to work with DC, which makes them, at least, need the use of an AC/DC converter.

How much could this devices consume? Is it relevant? Should I worry about it and try to reduce or optimize the number of connected devices?
