Zigbee communication level signal control

[AlexLV]

Hi,

In Zigbee application is possible see device's communication level signal. But it is not possible to attach to groups. If device is lost, it is not possible to catch this moment.

is it possible somehow control communication level signal over script or add it to application? With battery low level and battery status all is clear..

If this is not possible, how better control device presence - create timer and control change of received data?    

BR,

Alex

If you have low signal levels you can place a permanently powered device somewhere in between LM and sensors. It will act a router/repeater. Keep in mind that the signal level is only for the last hop. ZigBee is a mesh network so the data can pass multiple hops. The latest ZigBee app can show the network map with signal levels between nodes.
For monitoring you can use group address updatetime property and the current time (os.time()) to calculate when it was last updated.

You can add device signal level to group address when you use script.
Residental script -> Sleep interval 0 

Code:

if not zb then
  zb = require('applibs.zigbee')
  zb.addcallback('04cf8cdf3c79d40c', function(msg)
    --log(msg)
      log('zigbee device link quality : ' .. msg.linkquality*100/255)
  end)
end

zb.loop(1)

Here is documentation about that:
