Weak batteries

Provided that the voltage value permits it, the motion
detector will remain ready for operation also if the battery
voltage is low. Depending on the particular load, it may be
possible to send transmissions again repeatedly, once the
batteries have been allowed a brief recovery period.
If the battery voltage is too weak, this will be displayed
in the Homematic IP app and directly on the device via
the device LED (E) (see „9.2 Error codes and flashing
sequences" on page 43). In this case, replace the empty
batteries by two new batteries (see „8 Replacing batteries"
on page 40).
