Is there a better way to write this automation for toggling and dimming lights?

Configuration
1

Hi all.
I’m using this zigbee switch/dimmer IKEA E1743 control via MQTT | Zigbee2MQTT on a Z2M lightbulb.

I tried using templates and variables, but I couldn’t figure out how to get the variables and pass them on as a condition for the options to choose from.

I used a rather simple “trigger by” step to determine which action to perform, but I’m sure there’s a better, more generic way to write this.
