I have a CC2530 with ZNP firmware connected over UART. I am able to start a coordinator and devices join the network (I receive ZDO_END_DEVICE_ANNCE messages). A number of devices (a light and a thermostat) join the network and I can send AF_DATA_REQUEST commands to get and set attributes. These devices remain on the network forever.
I have ZHA motion sensors that I need to connect to the coordinator too. When I power on the sensors I see a ZDO_END_DEVICE_ANNCE and I can get the active end points and the simple descriptor, however after a few seconds the sensors will issue a ZDO_LEAVE_IND and leave the coordinator. After a few more seconds the sensor re-joins the network. This happens with 2 door sensors and 1 motion sensor, so I assume this is an expected behavior
My questions are:
Why are these devices joining and leaving? Do I need to bind a cluster on the device to tell it to stay?
Here is the info on one of the motion sensors:
