I am new to Home Assistant but I am having a lot of fun so far by connecting Zigbee devices to my network. All my devices seem to work fine except of my smoke detectors. I have 3 smoke detectors from the brand “KlikAanKlikUit” and they are placed on every floor of my house. The issue I am having is that they randomly going “Unknown”, “Unavailable” or “Offline” and online again in Home Assistant. It is never the case that all 3 of them are online there is always 1 or 2 that are “Unknown”. Is there something wrong with my Zigbee network? I already added a Zigbee extender which did not make any difference. Or is there another reason why devices can have this behavior?
So you also have other zigbee devices then these smoke detectors and only the smoke detectors go offline?
What integration are you using and which coordinator/extender are you using and do you use extension cables for you coordinator, which is in a USB2.0 port?
Which smoke detectors do you use?
Yes I have 7 other Zigbee devices running without any issues. I am using the “Zigbee Home Automation” integration on a mini pc server which runs Home Assistant in docker. To the server I attached the “Sonoff Zigbee 3.0 USB Dongle Plus” usb dongle into a USB3.0 port. I don’t use any other extension cables. I do have a “TRÅDFRI” signal booster from Ikea, but I don’t notice any difference with or without the booster. The smoke detectors have the same issues and the rest of my devices are still running correctly. The smoke detectors I use are from the brand “KlikAanKlikUit”.
Yes they only have 1 type of smoke detector. I did not know inserting the Zigbee dongle in a 3.0 port was a bad thing. With an extension cable you mean an extension cable inserted into a USB2.0 port attached with the “Sonoff Zigbee 3.0 USB Dongle Plus”? Can you explain a bit why this is better?
