I've got an OS 3.2.3 system that I've been running for about two years now, and my dealer has been pushing me to upgrade to OS 3.4.0 for the new features and security patches.\n\nHere's where things went sideways. My dealer came out yesterday to perform the upgrade, and about halfway through the process, the EA-5 controller seemed to freeze up. The LED was doing this weird amber\u002Fred alternating pattern that none of us had seen before. After about 20 minutes of waiting, he decided to power cycle the controller, and that's when things got really bad.\n\nNow the controller boots up, but it's not seeing about half of my devices. I've got 47 devices total in my system - a mix of lighting (mostly Adaptive Phase dimmers), motorized shades, the doorbell camera, my Sonos integration, and various sensors. Post-upgrade, I'm only seeing 23 devices in the app. The lighting in my master bedroom, home theater, and the entire upstairs seems to have completely disappeared from the system.\n\nThe weird part is that some of these devices still physically work if I use their local controls. Like my theater dimmers respond to the wall buttons, but they're invisible to Control4 and obviously none of my scenes or automation work for those rooms anymore.\n\nMy dealer is stumped and has opened a ticket with Control4 support, but they're telling him it could be 3-5 business days before someone gets back to him. Meanwhile, I've got a house that's half-automated and my wife is NOT happy about the bedroom lights situation (she relies heavily on the goodnight scene).\n\nHas anyone experienced something similar during a firmware upgrade? A few specific questions:\n\n1. Is there any way to roll back to OS 3.2.3? My dealer says no, but I've seen some older forum posts suggesting it might be possible in certain situations.\n\n2. Could this be a ZigBee mesh issue? I'm wondering if the upgrade somehow disrupted the mesh network and maybe the devices just need to be re-discovered or rejoined?\n\n3. Is there a way I can check the controller logs myself, or is that something only the dealer can access through Composer Pro?\n\n4. Should I be worried about my programming? I had a lot of custom macros and conditional logic that took months to set up. If we have to rebuild from scratch, I might actually cry.\n\nAny advice, similar experiences, or just moral support would be greatly appreciated. I love my Control4 system when it works, but moments like this really test my patience with the whole proprietary ecosystem approach.",[26,32,40,46,53,57,64,70,75,79],{"id":17,"author":27,"author_avatar":28,"created_at":29,"vote_count":30,"is_accepted":16,"body":31},"HighEndIntegrator","https:\u002F\u002Fui-avatars.com\u002Fapi\u002F?name=HighEndIntegrator&background=random&color=fff&size=256&bold=true","2024-01-02T14:51:35.783238",70,"That amber\u002Fred LED pattern typically indicates a firmware corruption or incomplete write during the update process. The power cycle during an active firmware update is usually what causes these issues - the controller was likely still writing to flash memory. Unfortunately, your dealer made the wrong call there.\n\nRegarding your questions: No, you cannot roll back Control4 firmware - it's a one-way street by design. However, your programming should be intact in the project file your dealer has backed up (please tell me he backed up before starting). The missing devices are almost certainly a ZigBee mesh issue. When the controller firmware updates, sometimes the ZigBee radio firmware also updates, and this can cause devices to lose their network association.\n\nHave your dealer run a ZigBee diagnostic and try re-identifying the missing devices. They're probably still paired but just lost their route back to the controller.
