Hello!
I have Homeassistant running on a Raspberry PI with a Sonoff Zigbee Stick 3meters away from the PI with an extension cable plugged into a usb2.0 port. All my devices seem to work fine except some of my smoke detectors. I have 10 smoke detectors from the brand “KlikAanKlikUit” and they are placed in every room in my house. The issue I am having is that 3 of them are going “Unknown”, “Unavailable” or “Offline” at the same time every day. I have attached a picture of my network and history. I have a fairly big network with 30 devices. Most of them are routers placed almost next to the smoke detectors that go offline.
