I'd like some help double-checking my wiring plan. I've replaced my own switches before but I'm not an electrician. I need to make 100% sure of what I'm doing here.
The setup
I'm in North America with "normal" single pole switches. A single switch will controls/will controll a single light.
Each of my wall switch boxes is wired simply and with a neutral. To be clear, each box has line, load, a neutral wire from the source capped with a wire nut that connects to the neutral going to the light, and ground.
I believe this is how my lights are wired:

What I want to achieve
- Each light's brightness can now be automated by Node-red/Home Assistant.
- The light switch no longer functions as an on/off.
- Toggling the switch will send a MQTT message to a topic for Node-red to process further.
My equipment
- Leviton Decora Rocker Single-Pole Wall Light Switch. Residential Grade, Non-Grounding, Quickwire Push-In & Side Wired, x3
- Shelly Dimmer 2, x3
Preface
I understand that the [Shelly L] terminals are all connected. So, the following is my plan for wiring, but I think I understand that line and load could be connected to either shelly L terminal.
My wiring plan in the switch box
Line -> [Shelly L1].
Load -> [Shelly L2]. (these are interchangeable)
Decora screw terminal 1 -> [Shelly SW1].
Decora screw terminal 2 -> [Shelly SW2]. (these are interchangeable)
I will remove the wire nut connecting the neutral wire together. Then:
Neutral wire connected to the current source -> [Shelly N]
Neutral wire connected to the light -> [Shelly O]
Is this correct? I used this Shelly wiring diagram as a guide. But, diagrams confuse me a bit. Thanks for your help!
