The connection between Clock PMS+ and Messerschmitt empowers you and your staff to focus on guests instead of having to switch between systems to issue a key card. Control access not only to the guest rooms, but also to common and special areas directly through the PMS+. 


Important: A Clock IoT device is required for this integration and it must be connected to the same local (internet) network as the Messerschmitt server.

The Communication Protocol that this integration uses is: Messerschmitt Coder Bridge API v2.

1. Access Clock PMS+ and navigate to section Settings->All Settings->Room Key settings->click on Messerschmitt.

2. Once the pop-up window is brought up, enter the respective information:

  • Active (1) - select to enable the interface once all configurations are completed.
  • API user (2) - select the Clock IoT device.
  • Server host (3) - enter the IP address of the Messerschmitt server. 

Important: Please consider if there is SSL enabled. If there is, you need to start with https://, while if it isn't, you need to start with http://.  For example, if SSL enabled, host IP and port 7773, you must enter 

  • Username (4) - enter your username for Messerschmitt Coder Bridge API v2.
  • Password (5) - enter your password for Messerschmitt Coder Bridge API v2.


Once you've added the integration details, save and enter the encoder/s details by clicking 'Add' under section 'Room key Encoder'.

You will be presented with two fields to complete:

  • Name (1) - enter the name of the encoder. You will see this name within Clock PMS+. It can be very useful if you operate with many encoders as the name will assist you to distinguish between them and select the correct one when you encode a card.
  • Identifier (2) - this is the 'name' of the encoder within Messerschmitt. The encoder needs to be firstly added within their system and then add its 'name' here. Usually the identifier is numeric.

Key card validity

In the section 'Room key settings' you can also add default 'From' and 'To' times for the key validity, respectively for the Arrival and Departure days. (1)

Additionally, you can control if key cards can be encoded only for checked-in bookings or also for expected ones. (2)

Door codes

For the interface to code cards for the correct doors, you need to complete the mapping for each of them.

Navigate to menu Settings->All Settings->Rooms->edit each room. Enter the code that you have set in Messerschmitt for this room in the field 'Room door code(s)' (3). You can only have 1 code per room.

Common doors/Special areas

The interface also supports access control to common doors or special areas such as Main entrance door, parking entrance, SPA, etc.

Firstly, you need to define them in Messerschmitt and afterwards enter their code in the field 'Common door codes'. The code can only be numeric.

Example: If in Messerschmitt you have defined 1 for Main entrance; 2 for parking entrance and 3 for SPA entrance, and you give constant access to the Main entrance and Parking, you need to enter "1, 2" in the field. This way, all guests staying in the room will have access to the following doors - Room, Main, Parking - at the very least. If the guest would like to use SPA, you can additionally add access to it through the booking.
