The window unit installation was easy after watching the Frigidaire installation available on youTube.  There were a lot of easy steps but if you watch the video it is not difficult.  The WiFi connectivity is not consistent and lacks in quality that was why I deducted one star.  Please consider open source usage and look into the WiFi signal dropping.  I have a mesh system and the actual Gateway is 6' away from the unit and still the signal drops.
