Button Controller has been upgraded in two respects. These new features are only available in newly created Button Controller instances. Your existing Button Controller instances will still use the previous version of Button Controller. You may choose to remove and recreate an old instance should you need any of these features for an existing instance.
You may now define actions for up to 8 different buttons in Button Controller (previously 7).
Integrated with Rule Machine
You can now run rules, run rule actions, run actions, set Private Boolean, stop actions, pause rules and resume rules from Button Controller.
Not sure whether hubitat would treat these devices as buttons, but from what I’ve read in the ST forum there are z-wave switches by Homeseer and GE (the newest generation of z-wave plus switches, I think) that support double-tap.
@bravenel, is it possible to add the capability to trigger a RM Action in button controller? I have several actions set up to be called by multiple rules and buttons. I have created rules for the buttons but it would be nice to be able to contain everything under Button Controller.
