Home Assistant Add-on that allows to capture the KlikAanKlikUit Doorbell with RTL-SDR.

RTL433 to MQTT Bridge hass.io addon

A hass.io addon for a software defined radio tuned to listen for 433MHz RF transmissions and republish the data via MQTT

This hass.io addon is based on https://github.com/james-fry/hassio-addons/tree/master/rtl4332mqtt, which is in turn based on Chris Kacerguis' project here: https://github.com/chriskacerguis/honeywell2mqtt, which is in turn based on Marco Verleun's rtl2mqtt image here: https://github.com/roflmao/rtl2mqtt

Modified by Gerrit-Jan de Bruin to work specifically for the KAKU ACDB-7000A (https://klikaanklikuit.nl/product/draadloze-drukknop/).

Usage

1. Install the addon: git clone https://github.com/gerritjandebruin/home-assistant-kaku-doorbell.git /addons or by Supervisor -> Add-on Store -> Options -> Repositories -> Add https://github.com/gerritjandebruin/home-assistant-kaku-doorbell.git.

2. Use addon configuration to configure:

• mqtt_host (default localhost)
• mqtt_user
• mqtt_password
• mqtt_topic (default homeassistant/sensor/doorbell)
• protocol (see https://github.com/merbanan/rtl_433 for more details inc protocol IDs, default 96)
• deviceid (Will only respond to this specific device id. Obtain this id by running the add-on, activate your device and look to the add-on logs.)

3. This add-on uses MQTT auto-discovery, to set up a device trigger (https://www.home-assistant.io/integrations/device_trigger.mqtt/)

Hardware

This has been tested and used with the following hardware:

• KAKU ACDB-7000A (https://www.gamma.nl/assortiment/klikaanklikuit-deurbel-set-acdb-6600ac/p/B413295)
• cheap rtl receiver (aliexpress.com)
• HASS.IO on old laptop, see https://github.com/gerritjandebruin/home-assistant

Total costs: +- €35, including chime and doorbell. Beat that Ring! (And this is way more privacy friendly.)

Automations

To use this device in automations, please make use of the visual editor and choose under trigger for "Device". You should see your device as soon as the add-on starts.

In my case, I create a notification for every device that the doorbell rang, see https://github.com/gerritjandebruin/home-assistant/blob/a1145e7b9ec0b38e20aaa4893a0365a1e106976e/automations.yaml#L248.
