Thanks for your reply, the contact alarm goes off in an amount of time, like 2 minutes.
Alarm is than off but the door is still open.
In hue the door status is open.
The alarm seems only an alarm signal to mount an acoustic signal on it.
I would like to use the door open status.
Thanks,
Hmmm, thatās odd. My Aqara + Sonoff contact sensors do report an alarm for as long as the contact is open
(I know theyāre now HA devices, but it was the same when I had them paired with Homey zigbee)
@Doekse hi, could you please explain me why Philips hue contact sensor is listed in the recommended door sensors in your website when now you are writing it is not supported?
I just bough one and having issue to connect it even with the test app
It is supported within the Official Phillips Hue App, you donāt need the test version to get it to work since it has been pushed to stable two weeks ago 
Are you having trouble connecting it to the Hue Bridge? Or are you trying to connect it directly with Homey via Zigbee?
Thanks a lot for reply.
I am new to Homey, not experienced.
I dont have Hue bridge.
I tried the app Hue without bridge. But that also did not find the sensor.
So i tried via zigbee and it was found, but not working 
ā¦ i just named it Hue Contact Sensor, but nothibg else.
The sensor itself seems to be working, meaning it blicks once when opening, twice when closing the door.
Thanks for any help
Marian
It looks like you misunderstand how contact sensors work within a Homey context: they cannot be turned on/off, you can only use them as input device in flows, where you can start a flow when the contact sensor triggers.
It looks like itās working fine.
The Hue App without a Bridge isnāt officially supported by us, you should contact the community developer to add support for the sensor
Quote from your web - It seamlessly integrates with your Homey Pro through Zigbee directly or through the Hue Bridge.
Iām not trying to turn it on/off. Thats just default error message from Homey Pro.
I simply could not add it without the bridge using the community app (without bridge). Maybe I am doing something wrong.
What does ācould not add itā mean? Your screenshot shows it as a device so it was added.
Default error messages appear by default? What did you do to get this error message, or when did this error message appear? Something must have happened to trigger this message. Maybe you clicked on the tile?
I get your confusion.
When Homey returns ādevice added as unknown zigbee deviceā, it means: it is added as generic Homey zigbee device.
BUT, the incomprehensible thing here is, it also just adds devices which are not supported as generic zigbee device, like sensors. Thereās no alert or warning whatsoever 
Generic zigbee is very basic, only On/Off devices like lights and switches are supported, along with Dim and some Color control.
Like @Doekse wrote, probably this sensor is not supported yet by that app.
At the app store app page, you can find links to, like, forum topic/support email/issue reporting:
Many developers use github.com, and the so called issue tracker can be used for device requests.
Just follow the link āReport an issueā.
.
This is one of the odd and unfriendly sides of Athom unfortunately.
In this case, they market stuff which is only made possible by 3rd party independent developers 
But when you encounter issues, they just point to the developer, and donāt even tell you how one should do that.
Also no developer is 24/7 busy with his/her app(s), it can take a while.
To clarify, this part of the text should not have been included in the Best Buy Guide. It operates exclusively through the official Hue App, which requires the Hue Bridge. We apologize for any inconvenience this has caused and will make the necessary corrections.
And do note; we greatly value the dedication and effort of our community, and it is never our intention to exploit that commitment. 
Thanks a lot for very clear explanation and help!!
