Hi,
after over one year of try and error, my elvox 8879 is working with the nuki opener :
opening the door -> ok
ring detection -> ok
ring to open -> ok
doorbell suppression -> ok
Here is my manual:
1. Disassembling
First of all you have to remove both bus wires (from 1 and 2), then you can screw of the intercom from the wall and now you can carefully solve the circuit board from the case of the intercom.
2. Soldering:
Soldering of the blue and violet wire to the back (!) of the intercom´s circuit board (for opening the door later):
BLUE -> OPEN BUTTON
VIOLET -> GROUND
-> see @ attached pic
After the soldering, you can reassemble the intercom and reconnect the bus wires 1 and 2.
3. RING DETECTION/RING TO OPEN:
Connection of the red and black nuki wires to the intercom:
RED -> 5
BLACK -> 6S
-> see @ attached wiring diagram
Now you can close to case of the intercom.
4. CONFIGURATION of the intercom @ NUKI APP:
-> update the opener to beta 1.5.1
-> configurate the intercom as GENERIC ANALOGUE INTERCOM (!):
test 1: the opening of the door will work instantly -> confirmation
test 2: ring to open: the ring detection won´t work now but you still have to confirm that the door has been opened -> confirmation
5. App settings:
-> activate Auto Unlock @ Smart Actions
-> enable the protocol @ protocol
Opening the door will work now, but for the ring detection you have to: ->
6. PM to one of the nuki team members:
he/she has to activate the analogue ring detection @ app (i think it is a hidden setting), if he/she asks for the voltage: the setting with 9V works for me
7. ready, now you can detach the doorbell wire /plug for doorbell suppression:
-> pull the plug/wire from A+ and strip it
-> also see @ attached/last wiring diagram
Kindly,
Patricia
