Highlights

• Infrared, Bluetooth, and Wi-Fi smart home hub for controlling AV gear, game consoles, and smart devices.
• Pairs with Harmony mobile app and remotes for activity-based scene control.
• Exposes a local XMPP/JSON interface used by Home Assistant for start/stop activities and device commands.

Logitech discontinued new Harmony hardware in 2021 but continues to provide firmware updates and cloud services.

Enable XMPP mode in the Harmony app; Home Assistant will auto-discover the hub on the LAN.
