Thanks. I will try it
Update, a couple of months and the python method is still working awesome.
My only problem is where I have a PIR and a door sensor in the same short hallway. They often combine their signals in the eyes of the rfBridge and I get a random interpretation of aa rfcode. Not much I can do about that. It just shows an an unknown code …
Do you mean that when your PIR and door sensor send a signal, it results in a random code generated by RF Brisge that is not recognised by the automations mentioned above?
Can some one give me some help trying to figure out how to convert the Option 2 automation to Node-Red. I have it running now, I am just starting to setup node red and I can’t figure out how to set this up.
- alias: 'rfbridge_demultiplexer'
trigger:
- platform: mqtt
topic: tele/RF_Bridge/RESULT
action:
- service: python_script.rfbridge_demux
data_template:
payload: '{{trigger.payload_json.RfReceived.Data}}'
This is what I have for the flow but it doesn’t work.

If you’ve created a Node-Red flow, you may as well incorporate the python_script’s functionality into the flow. A single function node can replace the python_script. The only challenge is converting the script’s python code to the node’s Javascript.
After a little bit of experimentation, I’ve created a Node-Red function node that duplicates the functionality of the rfbridge_demultiplexer python_script.
The entire flow consists of four nodes:
From left to right:
-
RF Bridge is an mqtt in node subscribed to
tele/RF_Bridge/RESULT. - json node converts the payload from a string to an object.
- Demultiplexer is a function node.
- Publish is an mqtt out node.
The function node contains the following code:
var d = { 'A1A':['sensor1','ON','true'],
'A2A':['sensor1','OFF','true'],
'B1B':['sensor2','ON','false'],
'C1C':['sensor3','ON','false']
};
var p = msg.payload.RfReceived.Data;
if (p in d) {
msg.topic = "home/" + d[p][0];
msg.payload = d[p][1];
msg.retain = d[p][2];
msg.qos = 0;
}
else {
msg.topic = "home/unknown";
msg.payload = p;
msg.retain = "false";
msg.qos = 0;
}
return msg;
Obviously you will need to customize the function’s dictionary for your specific needs (and possibly the subscribed topic for the RF Bridge node).
Here's the flow's listing.

Thx! Mark and read.
WOW. Thank you very much. I was hoping for a hint to point me in the right direction not a full blown solution.
Now to import and figure how it works. Thanks So much.
Hi, I’m using Hassbian and trying to use the option 2 using demux. The script is triggered correctly but I couldn’t see the mqtt published at the end:
hass.services.call(‘mqtt’, ‘publish’, service_data, False)
I’m trying to monitor using mosquitto_sub with the topic specified in the python_script but it doesn’t seem to be published. Anything that I should check?
Thanks.
How are you confirming the script is triggered?
I have logger.info inside the script which show the service_data content and this is shown in the log. Is there anything special need to be done to publish through mqtt? The mqtt from RF bridge is triggered according to the log and calling the script.

I’m trying to monitor using mosquito_sub with topic = rfbridge/*.
Like the Thinking
but I did mine Differancely
I have this sensor
- platform: mqtt
name: "Last RF"
state_topic: "tele/RF_Bridge/RESULT"
value_template: '{{value_json.RfReceived.Data}}'
expire_after: 1
qos: 1
I find out its rf code then write the 1 automation to turn on/off toggle something
- id: His side Lamp
alias: His side Lamp
initial_state: 'on'
trigger:
- entity_id: sensor.last_rf
platform: state
to: '137854'
condition: []
action:
- data:
entity_id: light.his_side
service: light.toggle

Silly me, thanks for pointing it out. Yes, indeed, it does get triggered. Now to finish up my automation 
Thanks again.
Hi @123 I’ve been using your rfbridge_demux for a while now and it works perfectly with the Sonoff PIR sensors I have around
But recently I got one of those Digoo RF 433 remotes and I’ve been trying to get it to trigger a binary sensor (not sure if the right call) but by some reason I see it on the log and on the mosquitto mqtt but it does nothing on the HA side… wondering if it could be my eyes misisng out something?
This is my rfbridge_demux:
d = { '123456':['remotesos','ON','false'] # remote SOS option
}
p = data.get('payload')
if p is not None:
if p in d.keys():
service_data = {'topic':'home/{}'.format(d[p][0]), 'payload':'{}'.format(d[p][1]), 'qos':0, 'retain':'{}'.format(d[p][2])}
logger.warning('<rfbridge_demux> Received RF command: {}'.format(p))
else:
service_data = {'topic':'home/unknown', 'payload':'{}'.format(p), 'qos':0, 'retain':'false'}
logger.warning('<rfbridge_demux> Received unknown RF command: {}'.format(p))
hass.services.call('mqtt', 'publish', service_data, False)
This is what I see on the mqtt side:
tele/sonoff-rf001/RESULT {"RfReceived":{"Sync":12430,"Low":420,"High":1210,"Data":"123456","RfKey":"None"}}
home/remotesos ON
This is my binary_sensor:
- platform: mqtt
name: 'SOS'
state_topic: '/home/remotesos'
off_delay: 15
device_class: safety
I’ve tried changing the device_classes but no joy at all 
ps: the ‘123456’ is a fake code just for the sake of the post, the real one has the real 433 code.
Any ideas?
Thanks for the help.
The python_script will publish to this topic:
home/remotesos
However, your binary_sensor’s state_topic is set to:
/home/remotesos
Remove the leading slash from the binary_sensor’s state_topic.

OMG how did I not see that 
Thank you very much
Thank you! This is the solution I’ve been looking for to make my configuration a whole lot more manageable.
I’m very averse to the verbose nature of Yaml and find in general, HASS’s configuration to be it’s biggest downside - this kind of approach completely changes my feelings about the platform, thank you!

Hi All
Trying to go convert to strategy 2 but getting this error in my HA log:
Error while executing automation automation.rfbridge_demultiplexer. Service not found for call_service at pos 1: Unable to find service python_script/rfbridge_demux
My first time configuring python scripts on the system so started from step one.
Anything specific I should look for?
Did you put python_script: in your configuration.yaml?
