I am new with HA, and the Zigbee devices... but I have a ThirdReality Zigbee USBC Dongle https://3reality.com/product/3-0-usbc-dongle/ and a bunch of sensors and plugs. I am having issues with some of my devices that are about 30-40ft away from the dongle where I can't talk to them. How can I get better performance? I also remember at the time when I installed the dongle that it said that it was possibly going to be depricated and removed (or something like that). Is that just the dongle I have right now? should i be looking at a differet dongle, or getting rid of the zigbee all together?
I was under the impression that it was a mesh type system, and that every device was basically a repeater, but I am thinking that I might be mistaken on that. Is there a repeater or something I can use?
