My illumination channel 5 got into a weird state today and wouldn't let me delete one of the time periods. It kept displaying invalid argument encountered. I couldn't get past this in either the GCC or GHL app on my phone. Ended up having to use another illumination channel to get one of my T5's back operational. I couldn't even control the old channel using the timers. Is this a known bug? I'd like to reclaim that channel as it keeps all my lights in sequential order. JP
