weirdly enough i can lighten up the zigbee bulbs (lidl) i have with the light.turn_on fine, but a automation where i call the following service, the lights are not doing anything.
i created the above using the GUI, not coded it myself.
Before this, i used the device automation to turn off, instead of calling a service, and that worked fine.
Regarding the formatting - if you only select one entity in the UI you will not get a โ-โ, but if you select two and then delete one you will get a โ-โ. So both options work.
Have you tried it in Dev Tools? Iโd say either your service call isnโt actually running, or some other automation is turning the light back on before the 3 second transistion.
