Event - device has been/for at least

[facke02]

I have a HS switch that is not responding to the device has been/for at least that I have that's set to 1 hour. I think it has to do with the z-wave controller polling the device and changing the Last Change date/time.

It seems that every time the controller sends something to the switch the last change date gets updated. If I run the event manually it will work.

I'm new to all of this so I'm thinking there's an option or something that I need to do to get past this?

I have another HS switch that is a "neighbor" to this switch and it works just fine.

Thanks

If the last update time does keep changing, you can do something like this:



Just change the 20 minutes to 1 hour.

You need to check the box "Do not update device last change time if device value does not change:" on the device's configuration page. Or you can use Al's suggestion.

Wow, that was fast. Thank you both.

I knew it had to be something simple.

Is one method preferred over the other?

It is a matter of preference. For the type of event you are creating, the method you used will work fine. I tend to avoid using "This device has been/for at least..." because of the possibility of repeat triggers. Your event is controlling the device used as a trigger, so it will be fine. I would put 10 seconds in the "Cannot Re-Run For:" in the advanced options of the event just to compensate for any Z-Wave status reporting lag.

The way Al does it would be my preference (of the two), but it does take two events. The first event is just housekeeping, but is a good idea.

Thanks Randy and Al


I used Al's approach and created two new events. Seems more straight forward.

I also checked the box "Do not update device last change time if device value does not change:" on the device's configuration page. Not sure if I should be doing this or not. I know the new events will handle it if it's not checked.
