Everspring water alarm - how to be warned if it drops off?

[mlevin77]

I see this in my health scan:

2nd floor Bathroom Everspring Water Sensor Alarm Node 38 Root - Parent with 4 children Last Change Time 8/20/2020 at 12:43 AM - Period = 125 days 5 hours 28 mins

Exceded inactivity period and failed poll

according to this, it hasn't been heard from for 125 days. The device tab shows:

How do I get it to report in once in a while so that SDJ-Health knows it's alive when everything is fine? Do I set a non-0 polling interval on the Z-wave tab of the device?

Presumably this is a battery powered non-listening Z-Wave device. You should be monitoring it in the Battery Devices section of SDJ-Health which will monitor the wake-up notifications that it sends at regular intervals.

ah ok, they're showing up as fine in the SDJ battery devices section of the main devices web page, so I should set all the battery devices to be Ignored by the General Health config page?

and, I'm not quite clear on which ones I should set for Polling and which ones for Activity Checking. What's the right way to decide which you want for a given device?

thank you!!

Assuming that the device normally updates battery or whatever on a periodic (12 hour?), you can set an event to reset and start a countdown timer of, say, 13 or 25 hours. And create another event to send you an email, etc., if the timer reaches zero. The only time the timer will reach zero is when the device doesn’t do its update during the prescribed time.

Yes, if you are monitoring it as a battery device there is no need to be scanning it in the general section. The Battery Device monitoring will alert you when the device dies by detecting missed wake-ups. A device like this sits there for months with the only thing changing being the battery value, and that might be vary rarely. Monitoring activity is a waste of time. SDJ-Health monitors the wake-ups which will probably be something like every 6 hours, depending on the device and how it is set up. It will alert you when it misses a wake-up, as well as low battery etc. Just check on the SDJ-health tab, of your monitoring child for this device, that it is monitoring by 'wake-up calls in the log', see below.



The guide explains the different monitoring methods for battery devices and where they are appropriate. All Z-Wave 'non-listening' devices should be monitored by wake-up log messages. These devices will be detected automatically by the plug-in and appropriate monitoring child devices created. Once all your 'non-listening' devices have been detected you can set up monitoring for other battery device types which are 'listening', i.e. don't wake-up at predefined intervals. Examples are locks which you would normally choose to monitor by the polling method. If you need more advice on this just ask, providing more details of your devices.

If you add additional 'non-listening' battery devices to your system they will be detected automatically by the pi the first time they wake-up.

In the General Devices section of the program you can exclude these battery devices from the scans. One point is that they will only show up in the list to optionally exclude once they have been scanned and show a failure. You can add device references directly to the list by editing the SDJ-Health.ini file but it is easiest just to exclude them when they show up. If it is a battery powered temperature sensor or similar that is regularly updating then it will pass the General Devices scan and won't show as an option to exclude so just leave them in.
