Test event Residential Flexibility: third edition

Wednesday October 28th 2026 / Thursday October 29th

Two full days of testing

Join the third Residential Flexibility Test Event and help shape the future of interoperable energy solutions.
To support the development of seamless communication between Flexible Energy Intensive Devices (FEID) and Home Energy Management Systems (HEMS), ElaadNL is organising the third edition of this test event.

Participants will have the opportunity to test their hardware and software with products from other market parties in a practical, multi-vendor setting. It is a unique chance to validate interoperability, exchange insights and contribute directly to the next steps towards market-wide alignment.

Our shared ambition is to establish a certification process for interoperable HEMS and FEIDs by the end of 2026.

Watch the short film of the second test event in June 2026.

Why join?

Test interoperability in practice, learn from other participants and contribute to the development of future certification.

The test event is open to all producers and manufacturers of equipment that is within scope: HEMS, either physical or via the cloud, and EV chargers, stationary batteries, solar inverters and heat pumps.
