Aeotec Pico Switch (zigbee 3.0) as a light switch.
I have a standard installation in a new block (N, L, PE).
I need help reading this diagram and connecting to an external switch.

What exactly is coming out of S1 and what is coming out of this Q?
1. Do I feed LOAD from S1 to the switch from one side and LIVE from its other side?
2. What passes from Q?
The previous "non-smart" switch had only LOAD and LIVE.
