I am thinking of starting a home-wide project to reduce power consumption. For this, I think I should turn devices off that go into power-save mode. Manually turning them on and off seems to be a hassle. For example, I could easily have 10-12 devices in the TV cabinet however only 2-3 are in use at any one time. It would be great if I can turn the power off to other devices using Amazon Alexa (that I already have).
I know there are off-the-shelf power strips but they all seem to have 3-4 power points. I rather not have 3 different power strips if possible. I have a 10-point power strip that I would like to convert into smart strip using Arduino. Has anyone done such project? I have seen people controlling one device using Arduino but not a power strip.
I am good with electrical stuff; fairly new to Arduino (can do basic coding, a few sensors, LED strip etc.).
Thank you for any guidance.
