Hello Everyone, Thanks for the reply posts. Here is the "FULL" Story: After arriving to my clients house she informed me that when her power went out last night her "20kw Briggs and Stratton Generator" came online powering up ONE of her main electrical panel boxes. Luckily, All essential loads are backed up on the generator INCLUDING 80% off all lighting in her home, the router, 1000 Controller, and the 300 Controller that is running the Zigbee Network. And this morning upon arrival, the power was already restored by the Power Company and ALL Dimmers and Switches were back to NORMAL and functioning properly! So you may ask, whats the problem? Why did the switches start flashing red/green and become TOTALLY INOPERATIVE????? (I searched the knowlege base until 1:00am last night looking for this and could find nothing)! Heres the answer. I called tech support when I arrived on site and spoke to Dan. Here is what he said: All Control 4 switches and dimmers check in to the controller every 10seconds or so telling it Im OK and Im receiving 120volts at 60htz. (That was how it was Identified in Composer during the itial startup) What happens is when a generartor starts up, it may take a few minutes for the generator to level off and produce power at 120v and 60htz. If the switches try to check in every 10seconds and DO NOT SEE what they need, the go into "Self Preservation Mode" and WIL NOT OPERATE until the SAME 120v 60htz is restored from the original source. Hence the Power Company! That is why when I arrived this morning EVERYTHING was working, ALL devices was seeing the SAME voltage and Frequency that it was looking for! Dan from tech support said they have this problem alot on the islands that have alot of power outtages and go into generator backup. (Imagine that)! He did say there is a "temporary fix" He said you can open the "air gap" on the switch to re-boot the device and when it comes back up online and sees the generator power, it woiuld work because now its looking for voltage/frequency "LESS THAN" what the utility company is providing and what is being provided by the generator. (I was not able to verify that this actually works) BUT, here is the problem. When UTILITY POWER is restored, You will have to repeat the air gap switch procedure because the devices will go back to "Self Preservation Mode" and not be happy with the utility power! (I was not able to verify that this actually works) Heres what I decided to do: I called the Generator Installation Company to see if they can come out and ADJUST the voltage and frequency taps on the generator to match the power company output. I am waiting to here back from them and see if that is even possible. (I have not heard back from them yet). I know on larger commercial generators there are many adjustments you can make. Not sure on these smaller Home Generators. Kinda curios now because we also install generators (Generac 20kw) but this is the first time I have ever heard of this issue AND next month I am installing C4 in a clients house that we installed a Generac 20kw generator. Im hoping that this is just HER generator that needs to be serviced and adjusted to closer tolerances that will fix the problem. I will post again after the generator company comes out and services the unit. Craig
