No.

Sorry that we do not have a larger angle of mounting wedge for the doorbell. There is only one 15° mounting wedge within the package for doorbells.

You can purchase another 15° mounting wedge by contacting eufy customer service. With the second wedge attaching back-to-back to the first one, the doorbell can pan a total of 30-degree angle. But you need to find longer screws to mount the Mounting Bracket to the wall. 

Moreover, if you need a larger angle, such as 30° or 45°, you can find it from other stores (US only). Here is the link for your reference.
