Recently I’ve started adding ZigBee based devices to my home automation solution – specifically I’ve added the Husbzb-1 stick to my setup. This has the benefit of combining both a Z-Wave and Zigbee controller in the same physical device, so I get to be agnostic as to the devices I add.
My next step was to try out a Hive Motion Sensor, for no other reason then there was one in the local store and a quick Google showed that it was Zigbee based.
This device is interesting in terms of form factor – suits what I was planning quite well, and the channels it provides;
- Motion Intrusion (_intrusion) – Switch
- Temperature (_temperature) – Number:Temperature
- Tamper (_tamper) – Switch
- Motion Presence (_motion) – Switch
- Low Battery (_iaslowbattery) – Switch
- Battery Voltage (_batteryvoltage) – Number
- Illuminance (_illuminance) – Number
So I actually ended up with more then I expected since neither the illuminance nor the temperature are referenced in any documentation that I can find. I’ve no clue what the difference between Motion Intrusion and Motion Presence are though – both seem to trigger at the same time… will update when I learn more.
The other interesting thing is that on the very first trigger, the state is updated from NULL to ON for presence (_intrusion and _motion), but the sensor itself never seems to trigger a state change to OFF. In order to handle this, I’ve defined an item, subscribed to the _motion channel, and then a rule to reset it back to off after 5 mins.
var Timer vFrontDoor_holdDown = null
rule "Reset Front Door trigger"
when
Item FrontDoorMotion changed to ON
then
if(vFrontDoor_holdDown === null || vFrontDoor_holdDown.hasTerminated){
vFrontDoor_holdDown = createTimer(now.plusMinutes(5), [|
postUpdate(FrontDoorMotion, OFF)
vFrontDoor_holdDown = null
])
}
else{
vFrontDoor_holdDown.reschedule(now.plusMinutes(5))
}
end
