What protocol do you use? Using ZigBee, my sensors (temp, leak, doors) last about 2 years
Mostly Zigbee. Depending on the sensor, location and activity I'm getting between 6-18 months per battery, but I do have a lot of sensor, so there's a regular churn of batteries.
I've had ZigBee door/window sensors last as little as a few weeks on a AAA battery, making them practically unusable.
