8.1
Weak battery
Provided that the voltage value permits it, the remote
control 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
(A)
(see
„8.2 Command not confirmed“
on page 34
), In this case, replace the empty batteries
by two new batteries (see
„6 Replacing batteries“ on page
32
).
8.2
Command not confirmed
If at least one device does not confirm a command, the
device LED
(A)
lights up red at the end of the failed trans-
mission process. The failed transmission may be caused
by radio interference (see
„8.3 Duty cycle“ on page 35
).
This may be caused by the following:
• device cannot be reached,
• device is unable to execute the command (load
failure, mechanical blockade, etc.) or
• device defective.
