Fibaro fgt-001 thermostatic valve battery life?

Have just changed to smartthings V3 hub from Vera plus.
The battery life on the fibaro valves lasts about a week since connecting to smartthings hub.
Does anybody know why?

Hi, I have the same problem with my FGT-001, in 3 days loses 50% of battery.
Does anyone have any solution? what drivers do you use?
