Hi I am new to HA and Zigbee, I am using a Sonoff Zigbee 3.0 USB Dongle Plus as coordinator and I have 2 Sonnoff Temperature and Humidity sensors to test things out.
I have tried both ZHA and Zigbee2MQTT with these devices and I am having a lot of problems with keeping the sensors online. With ZHA I cannot pair the sensors unless they are right next to the coordinator, its a little better with Zigbee2MQTT but the devices often do not complete the interview process. When I move the sensors to the places I want them they lose connections often for many hours and sometimes they drop off completely.
I live in a reasonably large house, my testing has taken place no more than about 5-10 meters from the coordinator so I think I need to look at strengthening the zigbee network by adding devices to for a mesh.
I have been looking for options for mains powered devices that act as Zigbee routers but other than Lightbulbs (which I don’t want or need) and plugs that go in existing sockets I cant find anything.
Can anyone recommend some affordable reliable zigbee router devices that I can use to form a decent zigbee mesh. I am based in the UK so after devices available here.
