Fibaro dimmer 2: set brightness to 100% for 60 seconds then return to original brightness

What homey software are you on? V2.0?
I have not installed v2.0 yet. If you are on v2 you need to install a beta version
(Timer (v0.4.3 stable (Homey V1.5) - 0.7.2 beta (Homey V2)) - (FKA Then More) add Timers to temporarily turn on devices)
