Minimum Number of Devices for Zigbee Mesh Reliability?

Also note that some zigbee devices don’t work with repeaters, like Xiaomi.

The ones that don’t work with other ZHA repeaters, though, should only be those that are not using the ZHA profile. The original Xiaomi devices are popular because they very cheap, but they are not certified to work with anything except their own controller. So they do have some idiosyncrasies.

FAQ: Zigbee Application Profiles, or why not all zigbee devices work with SmartThings

Zigbee is always zigbee, but the standard allows for different "profiles,"including manufacturer proprietary ones. [image] These are not all able to communicate with each other, they don’t even use the same addressing schemes. SmartThings uses the Zigbee Home Automation profile (ZHA 1.2) and part of the Zigbee 3.0 profile. Devices using other zigbee profiles may be able to join to the network, but their communications may not be understood, or they may frequently drop off because they don’t receive a handshake message they are expecting. There a lot of different ways to explain this, but I think one of the easiest is to think of zigbee as a post office and the different profiles as different languages. The outside envelope for different messages may look similar, have a specific format…
