The non A version works for sure. The issue I had was seeing the routing of them through the xbee but that has since been resolved with the latest settings for my xbee. I now see everything being mapped properly and they are staying online.
I also have a webcore script monitoring all of my xiaomi devices. If they don’t check in within the last 2 hours it notifies me. I have almost 50 devices and every now and then one doesn’t check in on 2 hours but does in the 3rd.
They are running great. Not perfect but I also see people have similar issues with no xiaomi devices as well.
