Hi Claudio,
I modified the python script suggest by Graham, instead send the message to binary sensor using http I used paho-mqtt python library to publish the message.
i.e publish.single(“hass/sensor/motion_sensor_1”,“ON”,hostname=“localhost”, auth=auth)
If you want in details, I can share my configuration to you.
Viet Luu
for future reference i can give you a third option.
let the script write the values to a small file and let HA read the value from the file.
it has the same advantage as MQTT (the last sensorvalues are Always known at restart) but there is no need to set up a MQTT server for it.
yes please. I am a newb still trying to understan it all. I do have mqtt (mosquitto) installed in the same pi3 where I ran HASS.
On the same pi3 I have a superetherodyne txrx but which I am not able to make it work though.
My goal is to use cheaper 433RF PIR sensor to give motion detection signal to HASS and use it for automation.
Help appreciated
Hi Claudio,
Look like your goal is same as mine. I installed mqtt (mosquitto) in the same pi and got superetherodyne transmitter and receiver.
Anyway below is my code:

Is it all working fine?
My superetherodyne connected directly to the pi is not working (codes are not registered by two 433RF remotes that I used.
As signal detector code I used 2 different from yours, now I am going to try yours.
On some forum are suggesting to step down Data voltage from 5v (of transceiver) to 3,3v of pi3
QUOTE rf signal detection (this script need to run all the time): #You need find update your pir motion rf code also, your topic name
yes but how to I find/update my pir motion code …
as a side note I also have this error (at the moment the code is a fake one since I did not manage to sniff the codes)

rfdevice.cleanup()Hi you now why the code is correctly going from of to on, but then stays on??
Hi,
I made my RF433 PIR Motion/MQTT automation with appdaemon. A true/smart motion is considered If two (o more) signals arrive to mqtt topic between a X period of time. if a true motion is detected and the alarm state is “armed”, send me a notification (telegram).
The sensor:
- platform: mqtt
name: "PIR Comedor"
state_topic: "home/433toMQTT"
command_topic: "home/commands/MQTTto433/PLSL_307/433_1"
payload_on: "xxxxxxxx" #put your RF Code here
payload_off: "OFF_PIR_COMEDOR"
optimistic: false
retain: false
device_class: motion
The config of the script:
pir_motion_1:
alarm_control_panel: alarm_control_panel.alarma
class: MotionPir
command_topic: home/commands/MQTTto433/PLSL_307/433_1
delay: '8'
module: motion
payload_off: OFF_PIR_COMEDOR
sensor: binary_sensor.pir_comedor
This is the my appdaemon script (the logs are in spanish 
):
import appdaemon.appapi as appapi
class MotionPir(appapi.AppDaemon):
def initialize(self):
self.handle = None
self.motion_counter = 0
self.sensor = self.args["sensor"]
