Did you read this?
You’ll need to pair the mains powered devices first, and try to use a few more than one lightbulb to create a good mesh network.
Also check your wifi vs. zigbee channel

Thank you for the links I didn’t know them
I only have 6 zigbeee devices connected directly not even close to the limit of 15
But I will try to delete and follow the advice connecting the powered devices first later today
I will post a follow up

What exactly happens when you try to add the devices? Do you get errors? Have you tried rebooting the Bridge before trying to add the devices? Can you add them as generic Zigbee devices?
Nothing happens it’s just searching
Yes I tried rebooting
Can you add them as generic Zigbee devices?
I don’t know what that means
Thomas
Probably doesn’t matter if you don’t know how to add them as generic device, it sounds like your devices either aren’t being put in pairing mode, or there’s something wrong with Homey.
If I try to add them to aqara hub the are added in a second
Therefore I’m looking at Homey
I understand. If your Homey Bridge has a hardware issue, we can’t help you. Please send an e-mail to support@athom.com
I just tried deleting 1 aqara device to see if I could attach another
So now I can’t connect neither one or another
It simply won’t allow me to connect to zigbee devices
Yes I will try to contact support
Option: does the bridge have a “zigbee reset” option (…More>Settings>Zigbee)? If yes you could give that a go.
Note you’ll have to pair all zigbee devices again and repair the flows with those devices.
I don’t think that is a option in homey bridge
I’ve got exactly the same problem. I basically bought the bridge for this, but it’s not useable. Greatly disappointed by this. And yes, I know this is a beta version but it is unusable for me without any confirmation that Homey is addressing this issue.
@JasperNLD @ThomasHussak
This suddenly popped into my mind:
From what I understand Aqara is producing updated models, with a different ID.
So it can be the case your sensors aren’t supported yet.
Here you can check if your model is supported:
If you read the thread you would find this:

Also got a useless answer from support
Thomas
As I wrote it popped up, and I thought it could be the issue with @JasperNLD.
Dunno anymore why I tagged you @ThomasHussak Bye!
When I read my answer I can see that I explained myself in a wrong way
It was absolutely not to say that your input was useless
I just tried to say that support reached back to me with a useless answer
Sorry if you misunderstood me, English is not my first language
Nope, they can connect. Suddenly stop working and then won’t reconnect. Next to that I can’t add more aqara sensors etc… Deleting one doesn’t make room to connect another one.
The ones that I have connected seems to be working fine but can’t connect more devices and if I delete one it cannot connect again
Hi,
I have the same problem with Aqara Door and Window Sensor and Water Leak Sensor.
These would be the first zigbee devices I connect to Homey, but they just won’t connect…
Is there a solution since Nov 2021?
Nothing like absolutely nothing
