  1. Your picture shows an ember thing type installed with the name CC2531. Is that a mistake? A CC2531 will not work if setup as an ember as they are different brands.

  2. What coordinator do you actually have and have you updated its firmware, if so what version firmware?

  3. Regarding Aqara devices, my opinion is don’t buy them unless you want to run them on the aqara hub and have a separate zigbee stick for other devices. They will only work if you are very careful about what other devices that you purchase that act as routers. See this post to learn more and this applies even if you use zigbee2mqtt…

I have a range of devices to test what is reliable and the aqara is only reliable IF it does not connect through any other router devices that don’t play well with that brand. I have sonoff and blitzwolf sensors and they both work fine in my limited testing. Sonoff are cheaper then the Aqara and dont seem to have the same compatibility issues.

  1. I found I sometimes get null readings until i push REFRESH on the web broswer. Updating to 3.2 milestone 4 seems so far to have fixed this. So give the refresh a push and see if that is the issue then upgrade if not on the latest milestone.
