A web interface for a CO2 monitor on a raspberry pi using an SGP-30 eCO2/TVOC sensor.

• Enable I2C via raspi-config
• Run sudo i2c-detect, if you see 0x58 is available, the SGP-30 should be connected
• If the sensor is showing remote I/O errors, you can try slowing the baudrate via the boot config
• If the i2c address happens to be something other than 0x58, change the value in /usr/local/goairmon/.env

1. Unzip the arm6, arm7, or amd64 tar from the dist directory to a temporary folder on the pi.
2. CD to the directory and run cmd/adduser -username={username} -password={password} to add a user.
3. You can change any values in the .env file and run the server via ./goairmon.
4. Run sudo ./install.sh to copy everything to /usr/local/goairmon and install goairmon.service.
5. Confirm the service started with sudo systemctl status goairmon
6. Open localhost:80 in the browser to view the web interface.

Build mage file arm6 to output to the dist directory.

Run sudo /usr/local/goairmon/uninstall.sh

1. Before adding or removing users, stop the service sudo systemctl stop goairmon
2. cd to /usr/local/goairmon
3. Run sudo cmd/adduser -username={username} -password={mypassword} to add a user
4. Run sudo cmd/rmuser -username={username} to remove a user
5. Start the service again sudo systemctl start goairmon
