Some dumb DIY work with my Raspberry Pi 3 + Home Assistant, making RPi a total control and monitor tower of my IoT devices and attached sensors.

YAY such a money-wasting DIY project! but at least I gave my rolling-on-the-floor Raspberry Pi 3 a usage ;)

• Buying a finished product is very costly!
• Building my own useful device is very accomplishing! isn't it?
• Make a good experience and keep my smol hardware/electrician skill!
• Hey, what's the problem? I just wanted to build this from scratch, so don't bother me
