Troubleshooting; Low Battery; Incorrect Pin Entry; Command Not Confirmed - HomeMatic IP HmIP-WKP Manual De Instalacion Y Uso

Troubleshooting

Used batteries should not be disposed of with regular domestic
waste! Instead, take them to your local battery disposal point.
Caution! There is a risk of explosion if the batteries are not replaced
correctly. Replace only with the same or equivalent type. Never re-
charge non-rechargeable batteries. Do not throw the batteries into
a fire. Do not expose batteries to excessive heat. Do not short-cir-
cuit batteries. Doing so will present a risk of explosion.
7 Troubleshooting
7.1

Low battery

Provided that the voltage value permits it, the Keypad will remain ready for
operation even if the battery voltage is low. Depending on the load, it may
be possible to transmit several times again once the batteries have been
allowed a brief recovery period.
If the battery voltage is too low, this will be displayed in the Homematic
IP app and directly on the device via the LED (G). In this case, replace the
used batteries with new ones (see „6 Changing the batteries" on page
31).
7.2

Incorrect pin entry

You define in the Homematic IP app how often a PIN code can be entered
incorrectly before the Keypad is locked. Once the Keypad is locked, you
can only reactivate it via the app. There is also a factory-set off time for
re-entering the PIN code. After the second incorrect entry, this off time is
automatically increased by 15 (30, 60, 120) seconds.
7.3

Command not confirmed

If at least one receiver does not confirm a command, the device LED (G)
lights up red at the end of the failed transmission process (depending on
the cause, the LED may light up with a delay of up to 10 sec). The failed
transmission may be caused by radio interference (see „10 General infor-
mation about radio operation" on page 36). This may be caused by the
following:
