The true intelligence of Pierre is in communication between the devices you want
This communication is the beginning of Pierre's possibilities and control options. It's up to you to chose what will trigger something into working. It can be one device or several devices at the same time.
You can for example set that the lights turn on when you open the gate, and at the same time cooling goes on. With Pierre, you can create different patterns, and just enjoy that it is working in your favor.
