Energy Management Without Cloud Dependency

Hi everyone, I’m a tech enthusiast looking to optimize my home’s energy usage without relying on cloud services. I have several rooms with multiple high hats and decor switches, all LED, but they still consume quite a bit of energy, especially with everyone home during the pandemic. I want to automate these switches to turn off during daylight hours but allow manual override.

I’m considering using Sonoff modules or a Zigbee setup with a hub. I have a Raspberry Pi and an existing PC that could serve as a server. The challenge is fitting Sonoff modules into standard 2-way switches and finding a cost-effective solution for multiple rooms.

Has anyone successfully integrated Zigbee devices without cloud dependency? Any tips on cheaper alternatives or DIY solutions would be greatly appreciated. I’m excited to explore these options and reduce my energy consumption while keeping things simple and local. Looking forward to your insights!
