Cloudflared Setup Guide on Raspberry Pi with Home Assistant

This guide will walk you through setting up Cloudflared on your system.

Pre-Requisites

You need to have administrative (sudo) access to your system.

Here are the steps to install Cloudflared.

UPDATE: 29-07-2023 - use native method for Amazon Linux 2023 at https://docs.docker.com/engine/install/centos/

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
