Yes, it is possible to create access codes for future use with this key safe. You can generate numeric codes via the ABUS HomeTec Pro app when connected by Bluetooth. However, to create or manage codes remotely (for example, while travelling), the key safe must be connected to a BRIDGE One device linked to your Wi-Fi network. This setup allows you to assign and delete numeric codes, including time-limited access codes, from anywhere via the internet. Thus, you can create a code remotely to allow access at a specific future time, such as from 2pm to 5pm tomorrow.
