This Blueprint uses a Zigbee2MQTT built sensor to sort out the 18 commands from the ZemiSmart ZM-RM02 Remote.
The split out of functions gives you the ability to assign local scripts or functions to do the things you want the remote to do. Functions that are left empty will simply do nothing.

There is sample code to make the template sensor in the help file on GitHib named Zigbee2MQTT - ZemiSmart ZM-RM02 Controller.md & in the community page related to this.

Within this blueprint there is an event handler that will latch the last command that the blueprint finds and sends that to the event buss. From there a simple Template sensor can grab it and show you the last action sent. Thie will help when setting up new functions and to troubleshoot strange behaviours.
