Hello! I just installed a 6WCL with compatible Philips bulbs on a gym just outside my front door. I can see the switch and turn it on/off in my HomeKit app but the lights won’t respond. I understand it may be a little far but there is an extender about 30 ft away, through a glass door. There is good network reception in the gym area. Another detail, the wall box is metallic and the plate is one of those hard plastic ones that break easily. Any suggestions?
