Z-Uno motion sensor on battery power

Hi everyone,
I have just discovered this product and read the documentation.
I don't understand how sleep mode works for motion sensors. Do I have to use ZUNO_SLEEPING_MODE_FREQUENTLY_AWAKE?
Is it possible to have a configuration where I have to change the batteries once a year?
Thanks for help.

No, use SLEEP. Your PIR element should wake up Z-Uno each time motion is detected

I agree but I've build a device with a few sensors and an LED and in this case ZUNO_SLEEPING_MODE_FREQUENTLY_AWAKE allowed me to turn on the LED so it offers functionality that is available in no commercial product
I ran it for a while and I'd say I could get below 0.1 mA stand-by current - not bad. Could have added a solar panel an a LiIon cell... But I needed my Z-Uno to do other stuff, so cannot really vouch for long term performance.
But surely it was fun to control a battery power LED light.
I posted this in 2017... Time flies
