What would cause all leak sensors to issue missing heatbeat msg at the same time?

[curmudgeon]

At 2:22 to day all 4 of my insteon leak sensors sent me a "missing heartbeat" email.

What could possibly cause this to happen?

Here's the error log for today:

 

Fri 2017/09/22 01:22:14 AM System -100 [DHCP] state=RENEW

Fri 2017/09/22 09:00:04 AM System -50001 -6

Fri 2017/09/22 01:22:23 PM System -100 [DHCP] state=RENEW

Fri 2017/09/22 01:57:54 PM System -170001 [TCP-Conn] -1/-140002, Portal-Dispatch

 

Don't know what any of this means or how it might have cause the problem with the leak sensors.

Coincidentally or not, two of my 5 leak sensors have given me a "missing heartbeat" alert twice yesterday after being quiet and happy for quite a long time.  It doesn't seem like those log messages would be related, though.  Mine are all fine now, and looking at the status variables I see that I forgot to init the latest one to 1 and that may look like a failure after a reboot of the ISY994.

 

Under normal conditions, "missing heartbeat" could indicate that the battery died (which should take 10 years) or it malfunctioned in some way.  I would go hit the button on the top and see if the green light shows up.

I have a common initialisation program for the whole ISY.  In that, I reset all MS low batts as well as all Leak detectors heartbeat detection programs. It's always a pain deciding where to keep these programs...all in one common place or with each device. Either way, it's always an easy forget to maintain thing, when so many other things are going on updating programs with new ideas.

I would personally not count on the battery lasting 10 years per Smarthomes advert. There have been a few instances where users have seen batches of Leak Sensors and Open ~ Close sensors come with stale batteries. If one assumes the batteries are still good because they tested them with a DMM. The next two things are to consider if the device is in range of the next dual band RF device. Lastly, the most common thing to impact a lack of heart beat status is interference in the home.

 

Last month I was field testing one of 15 weather alert radio's I have on hand for a long term project. I had this weather radio plugged into my island outlet ~ approx 24 hours later I received a (2) on the heart beat alert and Julie U.S. informed me of the same over the PA system. At the time I thought it was the rechargeable batteries I've been field testing vs using endless primary cells for the Open ~ Close sensors.

 

I measured the voltage on the rechargeable batteries and they were fine but decided to change them anyways. Another 24 hours had elapsed and the missed heart beat value of (2) remained?? I monitored this condition for another week because I was really curious to know what it my home was causing this failure. As soon as I unplugged the transformer from the island outlet a few hours later that same Open ~ Close sensor reported in fine.

 

In the kitchen there is no less than six Insteon dual band switches from KPL's to Switches.

 

Yet none of this mattered because the electrical system was contaminated by this weather radio transformer.

 

As a old school field test I could hear the interference being generated by another weather radio I had in place. The amount of RF static interference was extremely high and was also confirmed by my SWR meter.

 

Bottom line don't assume nothing has changed when the reality is electronics age and thus can inject random noise into the home. Also, keep in mind unless you're like me most people don't have a set pattern in terms of what and where they use their electronics. If you have kids it makes tracking down random events even harder because kids will be doing X vs Y all the time at different intervals.

What programs are you using to send the notifications? These or some variation?

Did your ISY have power toggled and restart?

Yes -  I am using the program by Belias that you linked in previous message.   No power toggle on the ISY.

I could be wrong, but it doesn't seem plausible that all 4 sensors send their heartbeat at exactly the same minute/time, (or miss it at the exact same time). So I would look at the other end of the chain, something may have happened with the notification program,  could you post that please?

Program has worked perfectly for the best part of 2 years,  so I doubt it suddenly went off the rails all by itself.   But you're right....it's also unlikely the 4 sensors lost their heartbeat all at once.

I suspect some kind of hiccup with the ISY.

Please post if this problem continues or not. The only logical explanation I can think of is the ISY restarted. If I recall, there was a note in that program set that a missed heart beat may take 36 hours to clear. I've received these notifications after a restart. Also, in my experience, I pulled all the batteries from my leak sensors and reinstalled them at nearly the same time. Now the heartbeats are nearly in sync. So if all batteries were installed at the same time I believe the heartbeats could be synced.

Here is a copy from the Belias program thread.

3d - Create a program called Leak Startup and ENABLE RUN AT START-UP
If
$iStartUp is 0

Then
Run Program 'KitchenSink - Variable Control 2' (Then Path)
Run Program 'StorageRoom - Variable Control 2' (Then Path)
Wait 5 seconds
$iStartUp = 1

Else
- No Actions - (To add one, press 'Action')

** Set to run at start-up **

Here is the thread where the power up program was copied from. Post #1

http://forum.universal-devices.com/topic/11566-leak-sensors-a-suggested-complete-program-package/page-1

 

Now mind you, this program will also cause notifications to happen at the same time, 25 hours after ISY power up, also,  if no heartbeats were detected.

I now realize that I was using the heartbeat incorrectly for a long time..
 
I simple created a program that looks for the heartbeat status and if not ON send me an email. One time I received an email and I see I was lucky because of a power outage, the waiting time for me is 6 hours..
 
What's the correct reporting time from sensors? every other 24 hours?

Use the Belias programs linked to in Post #10, this thread.
