We have a beta channel for evaluation of new and experimental features. Please contact us via email@example.com and we will further review your request (please mention your serial number (Z-Wave) or serial number (KNX)).
Once accepted you can put your Thinka on the beta channel yourself. Go to your Thinka's web interface and go to the Update Thinka page in the menu.
If you don't see the beta channel yet, please restart your Thinka first to get the updates.
Now you can switch your Thinka from stable to beta.
