Note on the button controllers after a Zooz FW update when using this driver.
Delete the old button controller and start over from scratch.
Brian has mapped eight buttons with pushed functions only. I have three Zen27 and two of them map button 1 to the upper paddle and one maps it to the lower. It was my first Zen27 so maybe it’s an older version of HW. Dunno. But before you start doing button controllers, watch the logs and press a button so you know which way it’s mapped.
I have also have a couple of my zen26 that don’t follow the other dozen I have.
