I just implemented the foundation of my home automation.

I installed NodeRED on a raspberry pi and it communicates with arduino through MQTT.

The good thing with this is that i control the hardware parts woth arduino and the automation logic with NodeRED.

NodeRED is much easier to use than HomeAssistant because of the extensibility and the use of NodeJs.

I have implemented an arduino library that makes the development on that an easy task.

I wanted to have everything on the local network and dont depend on the internet. We had some internet outage the past years and i dont want to lose the control of my house for that. Also, everything is much faster.

Every arduino can run on its own, that way even if the raspberry pi is out of order, i can open and close the lights using a button or a switch.

I second this approach. My home automation is 98% HomeKit (via homebridge) and 2% Node-RED (for a few custom MQTT message translations and a dinky little dashboard with metrics).
