The new standard makes it possible to stream data from sensors married to passive tags, by allocating a frequency channel to each device. When radio waves reaches a tag, the device wakes up and broadcasts the basic info it contains and then negotiates a clear channel on which to stream data.
Having passive sensors for smart home use would save me lot of time and money changing batteries. Interesting to see where this goes.
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.
