I don’t have CRMX linking key on my Cerise

The linking key can be accessed via the WebUI right next to the link and unlink buttons.

If the button doesn’t show up, you might need to update the CRMX TimoTwo module(s) inside Cerise.

To do this you will need to enable Bluetooth and connect with CRMX Toolbox, in the device section of the app, you should have the option to update.

💡Note that you might have to do multiple updates as there is one TimoTwo per universe.
