Aeon Labs Magnetic Door ZW089-A battery life

[norperu]

I have purchase 5 of the Aeon Labs Z-Wave Plus Magnetic Door - Window Recessed Sensor Gen 5 ZW089-A
However I have a problem with the battery life. I have changed the batteries for the second time and I still have the problem of it not lasting more than two months.
I thought that excluding them from the sensor polling would take care of the posible cyclical polling every 5 minutes.

I also have done the following changes to the configuration of the sensor:

parameter 121
4 bytes
Value: 272

Any ideas on how I can figure out if there is a problem with the sensor or with my Razberry?

How long is the wakeup interval that you configured?

I do not believe there is a way to find that out.
