Multiple Sonoff Bridges

[arby (Flo)]

Hi,

does anyone have an idea, how to implement multiple sonoff bridges in my setup.
i’ve 2 sonoff bridges because of the distance between my sensors and the brdiges.

my problem is, that sometimes only one of my sonoff bridges receives the rf-payload.
I’ve multiple door sensors and I don’t know, how to configure it to work with both sonoff bridges.

so the mqtt message of my binary_sensors could be received by any of those two sonoff bridges.

thanks for your inputs!
Florian

I have two sonoff rf bridges.

In automations.yaml :

- id: '1565365902541'
  alias: rfbridge_demultiplexer
  trigger:
  - platform: mqtt
    topic: home/OpenMQTTGateway/SRFBtoMQTT
  - platform: mqtt
    topic: home/OpenMQTTGateway1/SRFBtoMQTT
  action:
  - data_template:
      payload: '{{trigger.payload_json.value}}'
    service: python_script.rfbridge_demux

And the following python script (in the folder python script)

d = { '9823336':['ikea_switch1_sensor','ON','false'],
      '9823332':['ikea_switch2_sensor','ON','false'],
      '9823330':['ikea_switch3_sensor','ON','false'],
      '9823329':['ikea_switch4_sensor','ON','false'],
      '14163857':['doorbell_sensor','ON','false'],
      '13666408':['firealarm','ON','false'],
      '564886':['garagedoor','ON','false'],
      '16726408':['lichteetkamerboven','ON','false'],
      '16765268':['impuls','ON','false'],
      '16766303':['impulsb','OFF','false'],
      '16765265':['flamingo1','ON','false'],
      '352003':['buurvrouw','ON','false'],
      '1213858':['lichtwaskot','ON','false'],
      '1224498':['buurvrouw1','ON','false'],
      '16762193':['impulsa','OFF','false'],
      '16762196':['impulsa','ON','false'],
      '2291358':['voordeur','ON','true'],
      '2291351':['voordeur','OFF','true'],
      '152232' :['schuindak','ON','false']
    }


p = data.get('payload')

if p is not None:
  if p in d.keys():
    service_data = {'topic':'sensor/{}'.format(d[p][0]), 'payload':'{}'.format(d[p][1]), 'qos':0, 'retain':'{}'.format(d[p][2])}
  else:
    service_data = {'topic':'sensor/unknown', 'payload':'{}'.format(p), 'qos':0, 'retain':'false'}
    logger.error('<rfbridge_demux> Received unknown RF command: {}'.format(p))
  hass.services.call('mqtt', 'publish', service_data, False)

Sonoff RF Bridge. Strategies for receiving data

Here are two strategies for receiving payloads published by a Sonoff RF Bridge (flashed with Tasmota firmware). Strategy 1: value_template In this strategy, all sensors are subscribed to the same topic published by the RF Bridge. The topic's structure depends on how you defined it when you configured *your* RF Bridge. This example will use `tele/RF_Bridge/RESULT`. Change that to whatever you have set for your Bridge. Because all sensors are subscribed to the same topic, a sensor will receive pa…

thanks!!
sometimes a solution is so simple, that you can’t figure it out…
I took the Strategy 1 - and of course it worked perfect

thanks for your input!!

Hi @francisp I remember you writing about this somewhere, but i see you have 2 triggers (e.g. OR) but how do you prevent 2 bridges from running the automation one after the after if they both receive the message?

PS i noticed you trigger on OpenMQTT gateway topic. I use the tasmota mqtt topic instead:

tele/tasmota_5AF452/RESULT

Any reason why you use OpenMQTT gateway as a separate broker?
Many thanks

[francisp (Francis)]

Because, if you have 2 Rf Bridges with Openmqttgateway, Openmqttgateway sees the duplicate, and only sens it once to the broker. Tasmota does not.

[atv]

Ah, so there’s my answer then i guess :-). I wonder if i can do the same with Mosquito mqtt gw.

[francisp (Francis)]

My tasmotas and openmqttgateways (and zigbee2mqtt and esprflink) all use the same mosquitto.

[atv]

So are you saying you use both Mosquito and openmqtt gw ? I thought they did the same thing?

[francisp (Francis)]

No, openmqttgateway is a firmware, just as tasmota is. They both need access to a mqtt broker.

[atv]

Ahh i didn’t realise that. That explains your triggers.

So is openmqtt as good as tasmota? What is your experience with it so far if i may ask? Is it a good alternative to tasmota? And i guess as you said you use this to avoid duplicates that tasmota.

Shame tasmota doesn’t have that option.

[francisp (Francis)]

It is a little bit faster in decoding 433 Mhz messages than Tasmota.

[atv]

I’m tempted to use tasmota as i know it, but i’m worried it will mess with my automations if one bridge gets it faster then the other. I could of course map 433 sensors manually to sonoff bridges but that’s to static for my liking.

I’ll ask on the tasmota GitHub if there’s a way of doing this as with Openmqttgateway.

Thanks,
