If the relevant device App is already installed there is generally no internet connection and/or cloud service needed to include Z-Wave devices on a HP23. However, I don’t know how this works with the Homey Bridge. Theoretically, no internet connection/cloud service should also be required for this, because Z-Wave is local-
Afaik, HomeWizard devices need an internet connection/cloud service.
Regarding cloud services, a lot of maintenance work has been carried out at all locations in the last few days. To check the status follow this link → https://status.homey.app

@Bram_C, seems not to be a typically behavior. Of course, the Button could also be broken. But I would suggest to contact Athom support regarding this issue.
Don’t think they’ll give you a positive answer mate. For me the answer was “you have too much traffic on z-wave, case closed!”.
Hence, I’ve moved to Home Assistant and guess what, with almost twice as much as z-wave traffic I could include all my Fibaro buttons.
I haven’t read anything about the “too much traffic” problem for a long time, but unfortunately also no statement that the problem has been officially fixed. Furthermore, not every HP23 was or is affected by this problem. I have about 79 Z-Wave devices and have never had this problem.
Together with Athom support I did several tests and I have send information like the diagnostic report and an overview of my Z-Wave network. Unfortunately the real cause could not be found. They were able to tell me that the Fibaro The Button is known for being difficult to connect to Homey, which is not related to Homey but to the button itself. This is also what I was reading from other community members. It is still strange in my opinion as I have previous installed this device before without any issues, but now with both buttons I have issues connecting them to Homey. Anyway, there is not much more I can do.
About the support from Athom, for me it was a good experience. When submitting my request, I received the message that the expected reply time is 2-3 weeks. But I already received a reply within 5 business days. And every time I replied with information they requested, I got a response within 1-2 days. Unfortunately they were not able to fix this issue, but if it’s not related to Homey itself, I believe there is not much they can do.
It’s really sensitive on the exact timing and speed! You need to do it properly (hear the correct clicks) and pretty fast at a very similar klick timing. Then, it works surprisingly!
I’ve needed multiple tries to get it properly into the inclusion mode.
Same story for exclusion, when I did it to remove it from Home Center 3 Lite before starting inclusion with homey pro afterwards.
Hi @Poehler. Thanks for your advice. Again I tried several times to add the Fibaro button but without success. I think I have the timing and speed right of the inclusion mode, as I get two green marks saying that the button has been found. But during the installation proces, it fails for some reason.
Is an error notification shown, like Timeout?
Maybe the button is too far away from the Homey? Network Wide Inclusion (NWI) doesn’t really work well with HP23.
Or maybe the battery is almost drained. During the main inclusion process after the 2 green hooks, a relatively large amount of data must be exchanged. This is the part of the inclusion where the battery is relatively heavily loaded compared to usual. If the battery is too weak, this can lead to such problems.
I have the button appr. 10cm away from Homey and also changed the battery without success. Strangely, after each attempt it seems that Homey has created an ‘Unknown Node’ which is shown on the Developer Tool.
This indicates that something has gone wrong with the inclusion process. Remove the “Unknown Nodes” in DevTools (do you know how this works?), perform a PTP, then let Homey “organize” itself for at least 15-30 minutes and then try to include the Button again.
Thanks again @DirkG for your advice. Yes, I removed all the ‘Unknown Nodes’ and performed a Homey restart. No fix unfortunately.
After many attempts (lost count) and Homey restarts, this is the moment I give up…
I did contact Homey support as I mention on June 2024. According to Homey support the Fibaro Button is hard to connect. As this is not a Homey but a device issue, they couldn’t assist me any further…
I can’t return the button anymore to the place where I bought it, so I’ll take my loss.
I’m not saying you shouldn’t give up, but I would recommend keeping the button. I’ve had a very similar experience, including receiving the same response from Athom. One day, I had to reset the Z-Wave network for some reason, and I decided to try including the button again. It worked on the first attempt. That said, I’m also not suggesting you reset your Z-Wave network, as doing so would require significant effort to reconnect all devices and restore your flows.
