Hi guys,

I purchased a couple of the standalone PIR units with the intention of using these within the harmony setup to turn on our landing light, when movement is detected after midnight, but before 7am.

This works, however, as the 5 mins is up, and the light is due to turn off, the lamp then starts with a disco mode... flashing on and off rapidly.

Anyone any ideas why this is happening, and what changes to my setup I should make?

To flesh out the setup details, I have a dummy device setup, called night time - and a time triggered event, run at midnight, to set night time to true, and another to set the dummy device to false, at 7am. 

The action that detects a change in the pir, has a pre-req to check night time is on, then turns on the lamp for 5 mins.  A second action, 5 mins later, turns the lamp off.




Thanks
Tony

Hi Tony,

Can you tell us how you've configured the event?

Thanks

Is the lamp plugged into a Dimmer socket,
or a relay socket?

Keep in mind that the PIR sends an off
command after X minutes (x is set by a
dial on the underside).... So you
shouldn't need Harmony to send an Off
command (it shouldn't hurt, but your event
would be more efficient without it).

Perhaps try that first (can test by
manually setting the dummy night device
on).

You mention more than one PIR. Are they
all on different addresses? If not, one
may see the light going out as movement,
turning it back on! (the PIR's 'blind'
themselves for a few seconds after
switching, which is why this doesn't crop
up all the time.

Might be useful to enable the live log in
Harmony, so you can see what Harmony is
seeing /doing.

Hi Rob,

currently we only have the 1 PIR in action, the other is still in its blister pack unopened :-)

So to test, remove the turn lamp off command, then have another action, for when the pir turns off, to turn the lamp off?


Thanks
Tony

Yes, you've got it. The Off event doesn't require any
prerequisites - a straightforward PIR OFF = LAMP OFF will
do the job.
