Hi!
I'm looking to learn more about DIY Smart home options especially with lighting control and integration with Amazon Echo Dot. Anyone who has links or advise on how to get started, please share? Much appreciated.

Hi,
rather new to the Home automation scene, but heres some tips to get started.

1. Choose a gateway or system you prefer ( Fibaro / Vera / Zipato / Aeonlabs ), based on UI and the smart home integration things you want.
2. Plan your strategy, eg. what type of control do you want. Lights only, Dimmers, RGBW LEDs, Shutters etc
3. Setup test bed for your home automation. Minimally you should be familiar with some home electrical wiring basics, how to connect wires and dealing with switches.
4. Test functionality through the gateway.

For electrical wiring, I recommend reading this link to ensure your home is correctly wired to enable control of the lights

For eg, my setup ( currently incomplete but akan datang ) is as follows:
Vera Plus gateway
Fibaro Double Switch ( Gen 5 )
Aeonlabs 6-in-1 Sensor

Good luck!
