Payload:

'{"battery":100,"device":{"applicationVersion":3,"dateCode":"20161129","friendlyName":"0x00158d00045ad091","hardwareVersion":30,"ieeeAddr":"0x00158d00045ad091","manufacturerID":4151,"manufacturerName":"LUMI","model":"WSDCGQ11LM","networkAddress":28156,"powerSource":"Battery","softwareBuildID":"3000-0001","stackVersion":2,"type":"EndDevice","zclVersion":1},"humidity":66.73,"linkquality":null,"pressure":958,"temperature":19.44,"voltage":3215}'

This is for a Aqara temperature, humidity and pressure sensor (WSDCGQ11LM), but happens also for a Aqara door & window contact sensor (MCCGQ11LM).

Steps I took to try resolve the problem

For all payloads I checked, it seems the linkquality is null.
