To start I will let you know that I classify myself as a step above a novice and this is just my personal take on getting started.
I’m not too sure if you have any mqtt equipment. I could be wrong.
The next logical step for you is too work out what u want to automate.
For example if the 4 in 1 sensor is (Motion/Light/Temperature/Humidity) you could automate the lights to switch on if motion is detected and the light(lux) is below a certain threshold.
The post below should help with understanding how to create a rule to do this.
What is the right trigger for this rule?.
From personal experience you will never get your system set up correctly on first setup and it is ever evolving and you will be forever learning. The more you learn the more you will think to yourself. ‘I could get a rule to automate that’.
I have even seen in posts the wizard of rules @rlkoshak is still learning.
