Can you share more details on the GE Device you’re using? Is it still using a Groovy DTH or has it been updated to an Edge Driver?
What other options show up under the ‘changes to’ other than ‘down_2x’? Another approach would be to either add all the different values as triggers or add two triggers one for ‘is’ and one for ‘is not’ of the same value that way the rule will be triggered when any event occurs. Then you could test different physical actuations on the device and then check the SharpTools logs to see which (if any) of those events are reported.
For a button that reports which numeric button value was pressed, normally you would grab that data from the Extra Event Data, but as devices are switching over to Edge Drivers I’ve seen less reporting of the button via event data and more commonly see devices switching over to ‘components’ for each button.
If you can confirm which DTH or which driver you are using, that might make it easier to identify what type of current behavior your device is using.
Note that when if you added the Rule as a tile to your dashboard that when you tap on the rule tile, it directly executes the Flow portion of the rule and completely bypasses the Triggers section.
