I have 4 Fibaro Smoke Detectors ZWave Plus.

When i took the smoke detectors out of the box i was able to add them to Homey Pro (2023) succesfully and without any problem.

After few days, i noticed that 3 of the smoke detectors stopped waking up (or when waking up they were not able to communicate with Homey Pro).

I tried to wake them up manually but still i could not get any update on Homey Pro.

At this point i removed the smoke detectors from homey pro, i reset the smoke detectors as indicated on the manual, and i tried to add them back to Homey.

When doing so, i follow the steps with the two time three click of the B button succesfully but then Homey Pro tells me it is impossible to add the Smoke sensors and i need to try again later.

What should i do to re-add the smoke sensors on my Homey Pro?

Did you try this? Found it at the Fibaro manuals.

1. Disconnect the power supply.
2. Press and hold the B-button.
3. Connect the power supply while holding the B-button.
4. Wait around 10 seconds.
5. Release the B-button.
6. Disconnect the power supply.
7. Connect the power supply again.
8. After few seconds the device will be reset.

Thanks I solved this!  
Actually I had an issue on the overall zwave network so I restarted Homey and this fixed it!  
Thanks for your help
