CA3570 - Status reports but cannot control

I installed the device handler from LunkwillAndFook without any problems. I see the handler is associated with the switch. The switch is set up in Single Switch mode to control a pool pump. The Primary switch behavior is set to Switch All. My hub is about 15 feet away from the switch with only a wood frame wall between. My Smartthings app see the device and reports the status fine. I just can’t control the switch. I did not install any smartapps for the device, it didn’t seem like I would need to. I am new to this world so I don’t know what I could be missing.
