Is there any requirement to have a load?

Have a 2.5 which has a spare switch/load. I would like to use that side just as trigger to control a group, that is no load connected just the switch input to be used as trigger.

Just checking that 2.5 doesn’t require to see a load for it to accept a switch command and trigger a group. Effectively using that side as a dummy load. I can not see an issue but acquiesce to those more experienced with 2.5 shelly’s.
