Interoperability testing in a marketing free, collegial, and constructive working atmosphere
Invitation for developer presentations on current progress in standardization and certification
The Plugfest starts on Wednesday at 9:00 AM. The room will be available for participants until Friday at 4:00 PM for testing.
Please consider this for your travel arrangements. We look forward to successful testing!

The Plugfest was conceived to improve BACnet implementation and testing methods. It reduces both the risk of errors during commissioning and the number of faults in product development.
The Plugfest provides device testing in pairing sessions.
Following positive feedback after the last event we have again reserved slots for three short developer presentations. Applications must be submitted using the registration form.
The BIG-EU Plugfest registration and setup begin at 9:00 AM on Wednesday, June 10, 2026, and continue for three days until Friday. The agenda includes a social event on Thursday evening. On Friday, the room will be available for testing until 4:00 PM, so please consider this when making your travel arrangements.
The Plugfest is open to developers and product testers. Please note that sales and marketing staff will not be admitted. To ensure the event runs smoothly we ask you to respect some general terms: Plugfest participants need to be very familiar with the software and hardware that implements the capabilities being tested and are expected to have a good understanding of the BACnet protocol.
Allowed teams consist of two persons.
If the number of participants exceeds the maximum, BIG-EU member registrations will be given priority.
One person must register as “team captain” and take responsibility for completing all details about any devices that will be brought along. NOTE: It is mandatory for the team captain to provide all device details required for registration.
