Third Party Interface (TPI) is a upgrade feature that needs to be purchased on a per controller basis. With this feature enabled third party devices can send commands to the zencontrol application/room controllers via UDP.
This allows other devices the ability to override the current lighting settings. Installers can use this server to issue light level commands such as
- Change the light level of a group
- Recall scenes
zencontrol installers can also apply some additional logic on the controllers based on some changes (like scenes) and apply an override timeout.
All application / room controllers can be upgraded with the UDP. Please read How do I purchase control system upgrades to enable this feature.
Installers can use the attached reference document for UDP communications.
