The European Application Home Alliance (TEAHA) addresses networked home control applications and their complementarity to A/V networked applications. Its objective is to work with the A/V world to specify an open, secure, interoperable and seamless global home platform.

The TEAHA initiative has been structured into two phases. Phase 1 is this project. Phase 2 will involve a significant test programme. TEAHA approach is to define a suitable secure open middleware platform that will allow the seamless interworking of the wide variety of appliances found in a home environment (from the 3 cent device to the 300 euro device), over the wide variety of network solutions from the 100bit/s to the 100mbit/s.

The following research and innovation work is foreseen:
- Definition and development of an open middleware framework to ensure interoperability across heterogeneous networks. New network independent service discovery and security mechanisms will be defined and implemented;
- Development of new low-cost RF components supporting TEAHA middleware based on advanced RFCMOS technology;
- Development of ultra low-cost power-line communication allowing the connection of virtually any household small appliance;
- Development of new residential gateway components.

The route to industrial deployment will be addressed as TEAHA developed technology will be validated through three applications: white goods control, energy management, and residential gateway applications with seamless integration with networked A/V applications. Standardisation work will be carried out as well as marketing and dissemination.
