Reboot-Chromecast

Windows PowerShell script that will reboot Chromecast devices on my local network.
You will likely need to edit this script if you want to use it.

This script uses

gpsoauth by simon-weber
this gist by rithvikvibhu to retrieve the master_token and the access_token.
grpcurl by fullstorydev to invoke RPC on googlehomefoyer-pa.googleapis.com:443

The script assumes that you have

set an environment variable named HOMEGRAPH_SERVICE_ACCOUNT to your Google service account's email address <service-account-name>@<project-id>.iam.gserviceaccount.com
hard-coded your Google master token by setting the environment variable GOOGLE_MASTER_TOKEN to the value of your master token
In this case, I have set an environment variable entitled CHROMECASTMAC to my Chromecast MAC address. This isn't necessary, but it was convenient for me during testing as a way to quickly retrieve that value.

You will need to remove the parameter DeviceName's default value unless you also happen to have a Chromecast named Nick's Bedroom TV

Quick Start

Once you have set your environment variables, you can make Reboot-Chromecast available in a Windows PowerShell session by running the commands below.

Set-ExecutionPolicy Bypass -Scope Process -Force;
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;
