I assume that you guys are all talking about the actual button (ACDB-7000A).
However, I don’t have the button, I only have the receiver (ACDB-7000C) and I want HA to send a signal to it to tell the doorbell to ring.
How on earth do I add this device? I assume that I need to do something similar to how I added my Somfy RTS, by plugging the RFXcom device into a pc and then putting KAKU in learn mode.
But the details… I have no idea… does anyone know?
You don’t need to add the bell device. Just add a switch or input boolean with the rfxtrx platform and make up some valid device code. Your rfx module will broadcast that code. Put the bell in learn mode and switch on your virtual bell. That’s it.
Yup, that did it, who knew it was so easy 
Maybe someone who can help.
I have the Kaku doorbell. How do I set it automatic back to an off state after x seconds.
Now it always stays on.
Late reply but I did it like this:
alias: Doorbell_main_entrance
trigger:
- event_data:
entity_id: switch.main_entrance
state: group on
event_type: button_pressed
platform: event
action:
- data:
message: Main entrance
service: notify.ios_zinkens_iphone
- alias: ''
data:
entity_id: switch.main_entrance
service: switch.turn_on
- delay: 00:00:05
- data:
entity_id: switch.main_entrance
service: switch.turn_off
That way I will get a notification and the “dummy”-switch will switch to on for 5 sec and back to off.

Hi Jeroen,
No sure what the relation is between the rfx manager code and the doorbell id, but here’s my configuration of my rfxcom doorbell:
rfxtrx:
device: /dev/ttyUSB1
debug: false
automatic_add: true
devices:
0b11001f01a3cf4a0c010f80:
fire_event: True
If you put the automatic add option in, you should see the device com up in your devices:
After thats configured you can automate like this:
- alias: Doorbell pressed rfxcom
initial_state: true
trigger:
platform: state
entity_id: binary_sensor.ac_1a3cf4a_12
action:
- service: notify.telegram_x
data:
title: Doorbell pressed!
message: Doorbell pressed!
data:

hi how did you add a different sound?
I’ve tried this over a hunderd times but can’t find the right device code.
Can anybody give me a clue what device code I’ve to use?
I followed this manual: RFXCOM RFXtrx - Home Assistant
“*manually add a device, in the options window, an event code can be added in the field Enter event code to add” But I can’t find the right code 
no idea if this can help you, but I have this as device code (configuration.yaml):
rfxtrx:
device: /dev/serial/by-id/usb-RFXCOM_RFXtrx433_A11P1X5A-if00-port0
devices:
0b11000001417d5e01040f60:
fire_event: True
and this in my automation.yaml as trigger:
- alias: Deurbel Melding
trigger:
- platform: event
event_type: rfxtrx_event
event_data:
id_string: "1417d5e:1"
I have a kaku doorbell, and when pressing the button, a new device shows up. But when trigger it wit the gui, switch on or off, the chime does nothing.
What to do exactly?
Edit:
I figured it out, with the new switch I got from de rfxcom when pressing the doorbell, press on the chime the pairing button, and then fire the new switch from HA.
Thanks. I’ve tried to add the doorbell but no luck 
but try to add it in code in the configuration.yaml. So not like you did now by doing it through the GUI and adding as integration.
