Open Source Smart Home HUB 2.0 for Home Assistant

In this video, I'll show you how I built my Smart Home HUB 2.0 for Home Assistant. It is an open-source project, so you can download and edit whatever you want. JLCPCB ($2 for 1-4 layer PCBs; PCB assembly from $0): https://jlcpcb.com/?from=SSH I also created a Facebook group about this project. If you've any questions, or if you have great ideas on how to improve it, I cordially invite you there :) https://facebook.com/groups/766765251176707/ Project details: https://smartsolutions4home.com/ss4h-shh-smart-home-hub/ How to detect mains voltage with a microcontroller?: https://smartsolutions4home.com/detecting-mains-voltage-with-microcontroller/ My store: https://store.smartsolutions4home.com/ My website: https://smartsolutions4home.com/ If you like what I'm doing, consider supporting me: https://PayPal.Me/ss4h
