Raspberry Pi Ansible User Setup

This guide explains how to prepare your Raspberry Pi for Ansible automation by creating a dedicated user account with passwordless sudo and SSH key authentication.

1. Initial Access

• Boot your Raspberry Pi and ensure it is connected to your network.
• Find its hostname or IP address (e.g., raspberrypi.local or 192.168.x.x).
• From your control machine, connect using the default pi user:

# For first bootstrap (Password is laptop password)
[raspberrypi]
192.168.68.54 ansible_user=aquilesgomez
# For subsequent commands
[raspberrypi]
192.168.68.54 ansible_user=ansible

Intent

This is a project that will use a RaspberryPi in conjunction with homebridge to control multiple objects around the house.

Architecture

We will create multiple processes to monitor wand movements and another process to trigger homebridge requests.

sequenceDiagram
    actor a as Child
    box Wand Reader
        participant s as Sensor
        participant mp as Movement Processor
    end
    participant p as plug
    participant h as homebridge
    participant n as Network

    loop Periodically
        s -->> a: Emit IR
    end

    loop Upon IR Receive
        a ->> s: Give wand movement
        s ->> mp: Determine command
        mp ->> n: Make Rest API request to target plug
        n ->> h: Forward Request
        h ->> p: Trigger
    end
