Samsung Aircondition Remote Control
The original Samsung solution involves the air conditioning units registering in the cloud and using an app on the phone to remote control them. Found infos online on how their autodiscovery and protocol works and wrote my own client, now remote control over web-UI without relying on Samsungs service is possible. Our A/C’s are now not allowed to connect to the internet directly anymore and are managed by a custom web UI accessible via VPN tunnel.
