larryllix Posted September 27, 2014 Share Posted September 27, 2014 I had a power outage ISY reboot yesterday and last night I noticed some events that shouldn't have happened the way they did. I have a time dependant scene setting of my bedroom lamp so that the MS response is only about 15% brightness. Last night it went on at 100% in the middle of the night for some reason. The only reason I can think of is that the ISY clock was not set properly after the power outage/ISY reboot. Thus... a command to force the ISY clock to request the time base update may be useful and could used in the initialisation programs. I have it set to sync every 24 hours but have set it down to 8 hours now. Link to comment
Teken Posted September 27, 2014 Share Posted September 27, 2014 You mean at startup as an option? I am a little surprised the clock would be off after a power outage. If it was I cant see it being off for more than 5-10 minutes. Encrypted By: Phoenix Security Solutions Link to comment

Encrypted By: Phoenix Security Solutions An isolated command could be used wherever the user desires but I guess I don't see any usage for it other than bootup and then on a regular basis. hmmmm... is the clock battery-backed-up? Perhaps the clock is already initiated behind the scenes by the ISY init firmware? I can't think of how else these events could have happened twice in the middle of the night and then later in the early morning it functioned to the 15% level it should have. First thing this am I checked the program to see if it was intact figuring it got smudged somehow. Link to comment
Brian H Posted September 27, 2014 Share Posted September 27, 2014 The ISY99i had a Super Cap in it to keep the RTC clock running I believe six hours. I looked at the photos for the iSY994i Zwave kit and it looks like it also has a Super Cap on the main PCB. Link to comment
Teken Posted September 27, 2014 Share Posted September 27, 2014 I think the request to have an option to update the system clock is still a valid request. For me, it would simply serve as a fail over feature since my ISY is powered by three UPS systems. Link to comment
Michel Kohanim Posted September 28, 2014 Share Posted September 28, 2014 Hi larryllix, ISY can hold time for 6 hours (as Brian correctly suggested) and, in addition, upon boot up, it tries to synch with the NTP server (retries 3 times). Personally, I do not think the issue was Time synch related. Questions: 1. Do these programs have anything above and beyond time values 2. What's your grace period (Configuration | System) 3. Do you have Catchup schedules at restart checked (Configuration | System)? ... you may want to take a look at this article: http://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Scope,_Precedence_and_Execution_Order#Boot.2FStartup_Sequence_and_Program_Execution_Order With kind regards, Michel Link to comment

You never know and I will have a study and think about this some more. Thanks for the info pointer and your resolution hints. This sequence of power up events was coming in my questions one day when I get to thinking more about another quirk I have encountered. I guess this nullifies my thread idea as the only case for it's usage is moot with the time sync already incorporated into boot-up sequences. Link to comment
