mqttPartitionTopic receives multiple "D" events
Hi,

running the esp MQTT example, I have noticed whenever the motion detectors trigger, the mqttPartitionTopic receives multiple D events (I think 4 D's per trigger).  Unsure if this is the intended behaviour of the panel, dsc software or MQTT sketch ?

PS: this is from closed issue #89
