Hörmann4511652 Wall Wireless-Inner FIT 2-1 BS ~ for 2 Functions, Connection Option of max. 2 Controls via Cable, e.g. Key Button. Dimensions: 8 x 8 x 4.5 cm, Not specified

Easy to set up and install and it does the job. I would have given it 5 stars if the lock/unlock switch had worked and it had been a little bit smaller.

The product does what it says on the tin however instructions in German and even these didn’t show how to insert batteries. Had to use YouTube to find how to programme by pairing up with existing remote, even then it was a bit hit and miss. Suggest more comprehensive instructions and in English for U.K. customers.

Instructions that came were in German so had to spend time on the internet to find instructions in English which took some searching, so not a good start.Really struggled to get this button to work after copying the code from my Hormann remote sender as it would not operate the garage door opener. On pressing the button the door opener motor would not activate but noted that on the motor display code 11 was flashing, then the courtesy light activated but still no motor activation.After a lot of hair pulling and fiddling I discovered that by holding the button down on the wall switch for a long period the blue led light changed to red and then suddenly the motor activated and opened the door, I am not sure why this seemed to kick it into action as there is nothing in the instructions describing this action.My only other criticism is that it seems a large unit that only requires the use of the top half moon button to be pressed to open and close the garage door, I don’t know what the bottom half moon button is for as it does not activate anything or seem to have any use.I am sure a much smaller more robust switch could be manufactured.My garage door opener is the latest Hormann Supramatic E Series with integrated Bluetooth.

The 'learning' feature of this unit a little counter-intuitive to set-up but once done, it does the job well. You need to remember to make a long press (not quick) to ensure the signal gets to the garage door and the unit it larger than I'd have liked for a wall-mount. But recommended anyway.

Its a switch - but very easy to program with remotes.
