Doorbell button state from RF Bridge Tasmota

gunio · April 10, 2021, 8:10pm

Hello, I am struggling with making a config code in HA.
I would like to make a sensor which state changes when the doorbell is pressed.
I have a Sonoff RF Bridge flashed with Tasmota and Portisch.
I am able to receive the codes in the Tasmota console
after enetring rfraw177
when doorbell button is pressed:

20:48:29.894 CMD: rfraw 177
20:48:29.901 MQT: stat/RF_bridge/RESULT = {"RfRaw":"ON"}
20:48:29.929 MQT: tele/RF_bridge/RESULT = {"Time":"2021-04-10T20:48:29","RfRaw":{"Data":"AAA055"}}

How to build the configuration code that will make a sensor that show changes a state when button is pressed and then change the state to off.?

sheminasalam · April 11, 2021, 1:32am

I see instead of a constant payload, there are a number of different payloads like AA B1 03 0140 0352 11DA 28190908190819081818181818181819090909 55, AA B1 03 014A 0348 125C 28190908190819081818181818181819090909 55etc beings transmitted for the bell but if these codes are consistently sent every time. You can build a mqtt binary sensor like this.

binary_sensor:
  - platform: mqtt
    name: "Door Bell"
    payload_on: "AA B1 03 0140 0352 11DA 28190908190819081818181818181819090909 55"
    off_delay: 5
    state_topic: "tele/RF_bridge/RESULT"
    value_template: '{{ value_json.RfRaw.Data }}'

Thank you for quick response.
Unfortunately only some part of the code is constant.
This part is this:

xx xx xx xxxx xxxx xxxx 28190908190819081818181818181819090909 55

Can the code be more universal to this type of random code?

sheminasalam · April 11, 2021, 10:59am

I think this would work for you. Please try and let me know

binary_sensor:
  - platform: mqtt
    name: "Door Bell"
    payload_on: "true"
    off_delay: 5
    state_topic: "tele/RF_bridge/RESULT"
    value_template: '{{ '28190908190819081818181818181819090909 55' in  value_json.RfRaw.Data }}'

I don’t think that long number is not constant either. Are you sure?
I think only the first 6 or 8 digits and the last digits are constant but not in between.

This makes it hard to know the state. I’m struggling myself with that problem too.

gunio · April 11, 2021, 12:36pm

Unfortunately your code does not work.
To test it I had to change:

value_template: '{{ '28190908190819081818181818181819090909 55' in  value_json.RfRaw.Data }}'

to

value_template: "{{ '28190908190819081818181818181819090909 55' in  value_json.RfRaw.Data }}"

Otherwise the config test fails.
I also tried:

value_template: "{{ '28190908190819081818181818181819090909' in  value_json.RfRaw.Data }}"

but still no changes on doorbell status ;-(

gunio · April 11, 2021, 12:39pm

I am sure that the long part of the code is constant.
Look at the result from tasmota console after pressing the doorbell several times:

Sorry my friend, it does not work.

sheminasalam · April 11, 2021, 1:15pm

It worked when I tested it with my system but there might be something else. What is the error you are getting or is it that the binary sensor is not triggering ?

Please copy and paste the tasmota logs between ``` so that it appears as a code.

When you say “test” do you mean you pushed the doorbell button but the payload (specifically RfRaw.Data) in tele/RF_bridge/RESULT never changed?

gunio · April 11, 2021, 1:40pm

yes I pressed the doorbell several times

If a button press isn’t being automatically reported in tele/RF_bridge/RESULT then you may need to use a Tasmota Rule to do it.

bitrip · April 11, 2021, 1:43pm

  - platform: mqtt
    name: "Door Bell"
    off_delay: 5
    state_topic: "tele/RF_bridge/RESULT"
    value_template: '{{ value_json.RfRaw.Data.split(" ") [6]}}'
    payload_on: "28190908190819081818181818181819090909"

Does this work for you maybe?

You need to make sure it’s in rfraw 177 mode. You can do it with a rule to make that permanently.

gunio · April 11, 2021, 1:46pm

it works!!!
can I change off_delay to 1s ???

bitrip · April 11, 2021, 1:47pm

Good.
Yes you can change to 1s if you like.

FWIW, for an MQTT Binary Sensor, the default payloads representing on/off states are ON and OFF. Therefore the template only needs to match a few relevant characters and then report the appropriate ON/OFF values.

  - platform: mqtt
    name: Door Bell
    state_topic: tele/RF_bridge/RESULT
    value_template: "{{ 'ON' if ' 281909' in value_json.RfRaw.Data else 'OFF' }}"
    off_delay: 2
