I bought a few of THESE motion sensors
Got them paired and working with ZHA but, they keep going unavailable. They wont stay connected more than a few hours. They are less than 20 feet from my hub (I’ve got devices much further).
I also have a few of THESE Door/Window sensors. They also will not stay connected. When they work, they also stay on for about a minute when triggered
Any ideas I might try? Do I need to buy the Xaiomi hub (which defeats the purpose of buying these low priced devices)?
