I have a number of ikea sensors dotted in my house that trigger lights. Simple routine, motion, after sunset, lights on. There is one room that just wont trigger. Ive deleted the flow and rebuilt. Wont run App shows motion on sensors correctly Light is controllable in the app If i press ‘play’ on the app the flow works. Put it all together, nothing. So… is there any way to fault find why this one does not trigger? Thanks in advance ---

Sounds like an error in your flow. Make sure that the specific sensor shows the expected values in the app. Also make sure that these values change when you expect them to. I’m playing Cpt. Obvious, but when sensor values won’t change, nothing will happen. Then make sure that your flow trigger is waiting for the right device. I made a lot of ‘copy and paste’ mistakes in the past, when copying flows for another room. ---

Ill double check them again but its literally zone active, light on Thanks ---

Might help to post your flow. FWIW, I had a similar issue when installing a presence sensor into a new room. I copied and pasted an existing flow but forgot to change the test for light level, so it was using the light level from the wrong sensor. Andy ---

Is the sensor set up in the settings so that it’s part of the zone activity? Are there any other sensors that could affect zone activity in this room? ---

Remove the AND card. When that works, add the AND card like : it is NOT between 08:00 and 18:00. In your card 18:00 and 08:00 are on different dates and never true​😅 ---

In the past, this flow card didn’t work with these time specifications, that’s true. However, this is no longer a problem and the card should now work without any issues. There is also an explanation for this: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/2/b2b6cdc03d71ee0cff1d22403635ec4c3c48f28b.png) Translation: _If the second time is before the first time, the next day is assumed._ ---

This is exactly how this flow was when first set up on my HP23 and worked every time. After 6 at night, before 8am. I also tried after sunset and before 8am and still didnt trigger. So what are you saying it should be? ---

> [@Welshsmarthome](#): > > its literally zone active, light on If you go to the Advanced Settings section of the motion sensor’s device tile, there is an option ‘Exclude from Zone Activity’. Is that set to No? So the device is allowed to trigger zone activity. ![IMG_2476](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/f/9f53fff8c16526827c0fb25efb2691e9017615dc.jpeg) ---

My suggestion is/was to delete the AND card and to replace the WHEN by a Message card that writes a message to the time line, so you are sure you are testing the WHEN card. When the zone is active a blue dot is shown to the zone in the DEVICE tab. ---

You can add “simple log” cards so you can trace what steps in the fliw fail > **[Simple (Sys) Log | Homey](https://homey.app/it-it/app/nl.nielsdeklerk.log/Simple-(Sys)-Log/)** > > Use this app for Simple (Sys) Logging. ---

@Welshsmarthome, for clarification purposes only, because you replied on my post #8. I replied to the first post of @Rmb, in which he claimed that the time card would not work. I don’t know, why it‘s not displayed: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/a/bad029f6e412884b08a8e6a2935110d9fd391624.jpeg) In this post, I just wanted to clarify that the mentioned problem no longer exists. So your flow should generally work if the hardware is working and configured correctly, as I questioned in my post [#6](https://community.homey.app/t/flows-wont-trigger-how-to-find-out-why/151233/6). ---

And Maybe dimming a lamp to 1% is not bright enough to be noticed? ---

@Rmb, I had thought about that too. But it worked when I tested it with Philips Hue lamps. ---

Tried 3% still same outcome. Can use the app to physically dim the light to 1%. ---

Just a double check: I assume the motion sensor (or more specifically its tile) is actually part of the Bathroom zone in Homey? [Next page](https://community.homey.app/t/flows-wont-trigger-how-to-find-out-why/151233.md?page=2)
