# pi-room
## Step 0
- Enable ssh via `raspi-config`
- Enable i2c via `raspi-config`
Related issue and work around: https://github.com/yarnpkg/berry/issues/6174
### Need
```
root@raspberrypi:/home/pi/Desktop/projects/pi-room# node -v
v18.19.1
root@raspberrypi:/home/pi/Desktop/projects/pi-room# yarn -v
4.1.1
```
## Step 1
On your Local Machine:
Check for existing key pair: Use the command ls -al ~/.ssh to see if you already have an SSH key pair. This directory stores your SSH keys.
Generate a key pair (if not present): If there are no keys, create a new pair using ssh-keygen -t rsa -b 2048. This generates a public and private key (usually named id_rsa and id_rsa.pub).
Adding the key to Raspberry Pi:
Connect to Raspberry Pi (using password for now): SSH into your Raspberry Pi using the standard command ssh [email protected] (replace with Pi's username and IP if different). Enter the password when prompted.
Copy the Public Key: Use the ssh-copy-id -p PORT USER@RASPBERRY_IP_ADDRESS command. Replace the placeholders with your Raspberry Pi's details (port, username, and IP address). This copies the public key to the Pi's authorized_keys file.
Testing Passwordless Connection:
Disconnect and Try Again: Exit the SSH session on your local machine. Then try connecting again using ssh [email protected]. If the keys are set up correctly, you should be granted access without entering a password.
### Development
Remote ssh vscode extension
