None of the button devices i have are working in Hubitat. I have a few automations that used to work in ST using the default apps but are simply not working in HE. Buttons ranges from Inovelli's Red Switches (tap 2x and config button) and Smartthings own button.
I have tried everything: webCOre pistons, controller apps, RM. Nothing seems to work. I have checked the logs and they all seem active and responsive.
It helps a little. that log indicates that the button is working correctly.
The next step would be to check the automation. Can you provide details (and a screenshot?) of the configuration for whatever rule you have setup for the light?
Here is an example of one of my rules using Simple Automation Rules (a bult-in App you can install from the Apps screen). This will toggle a light with a button push.
