Be careful....the Iris v2 lots being sold now may not come with magnets. So, be warned.
That is not long battery life in my opinion. Good zigbee contact sensors go 3-5 years between replacements.
I found them here a while back.
They don't but I purchased magnets off Amazon for fairly cheap in lots of 10 to match the iris v2 sensors.
And they work? Then you're lucky.
Of course, they’re just magnets.

I just used the magnets and threw away the rest.
What brand does this? I would expect any contact sensor that also reports temperature to have a shorter battery.
They did do this, but I thought it was fixed in one of the latest updates.
Genereic Z-Wave Contact Sensor fixed double events for the following devices: * Ecolink Contact Sensor 2.5 * Ecolink Garage Door Tilt Sensor 2.5 * HomeSeer Contact Sensor
Same with the Xiaomi's.
Have them (20) running for 2+ years now, still on first batteries.
