To grab the script easily you can copy it from here:
https://raw.githubusercontent.com/james-fry/hassio-addons/master/rtl4332mqtt/rtl2mqtt.sh
Never mind, the link to the file worked. sorry bout that.
starting version 3.2.2
Starting RTL_433 with parameters:

This is where is gets a bit harder to debugā¦
Are you running hassio on resinos - ie from the Raspberry Pi image?
If so case Iām not sure how/if I can help debug as I am running hassio on ubuntu.
Its possible that resinos does not have the necessary RTL DVB drivers/kernel modules.
If you are running on a standard linux you can check that a device was found with lsusb.
You should see āRealtek Semiconductor Corp. RTL2838 DVB-Tā
e.g.:
james@hassio:~$ lsusb
Bus 001 Device 007: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
With hassio resinos/image you can check this with the terminal addon from here:
In the terminal run lsusb:
ā / lsusb
Bus 001 Device 007: ID 0bda:2838
Bus 002 Device 002: ID 0e0f:0003
Bus 002 Device 003: ID 0e0f:0002
Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0001
Itās the device ID 0bda:2838 that youāre looking forā¦
https://www.linuxtv.org/wiki/index.php/RealTek_RTL2832U
Not sure how far this gets us with debugging, but itās a start.
Could be that the USB device ID will still be shown even if the kernel mod/drivers are not loaded. I donāt know Iām afraid.
If you are running rpi image maybe there are some others on in the community here that can help further?
Nice!
Thanks for updating with your successā¦
Thanks for your great job! 
To share my setup: i had a RTL-capable usb tuner (https://www.amazon.it/gp/product/B013Q94CT6) and got from AliExpress a cheap 433MHz temperature and humidity sensor.
The configuration was quick and easy
{
"mqtt_host": "192.168.2.33",
"mqtt_user": "homeassistant",
"mqtt_password": "xxxxxxxx",
"mqtt_topic": "homeassistant/sensor/temperature",
"protocol": 3
}
This is the received payload (got from mqtt-spy):
{"time" : "2017-11-05 15:24:28", "model" : "Prologue sensor", "id" : 5,
"rid" : 198, "channel" : 1, "battery" : "OK", "button" : 0,
"temperature_C" : 21.500, "humidity" : 62}
This is the sensor configuration:
- platform: mqtt
name: sensore_433_temperatura
state_topic: "homeassistant/sensor/temperature"
unit_of_measurement: "Ā°C"
value_template: '{{ value_json.temperature_C }}'
- platform: mqtt
name: sensore_433_umidita
state_topic: "homeassistant/sensor/temperature"
unit_of_measurement: "%"
value_template: '{{ value_json.humidity }}'
The final result:

Glad itās working for you! Thanks for the feedback
Dasher isnāt auto starting despite being told to do so.
I have it configured properly and it starts/works fine when I hit start. Just not auto starting for some reason.
Hello folks,
I was reading this topic and also several other around the internet and I must say, Iām confuse.
I have a RPI with HASSIO and now I would like to integrate some RF modules (https://www.ebay.co.uk/itm/New-1-5PCS-315-433-Mhz-RF-Transmitter-Receiver-Wireless-Module-Arduino-ARMMCU/272472455163?hash=item3f709fb7fb:m:m7aadyB7z1lfOEfQW2zc6DA) to work with my shutter motor.
My problem is, how do I know that modules are visible into the HASSIO?
How do I scan the codes in use?
OK, Iām going just start with these questions :).
Thank you in advance!
BR,
jponte

Hi there @jponte, I made a simple addon that scan the codes using those cheap receivers and writes them in a MQTT sensor:
Thank you for your replyā¦ probably is a silly question, but how do I install your addon? Iām trying via browser adding the link to your addon and then Iām saving that link (https://home-assistant.io/hassio/installing_third_party_addons/), but then nothing appears to me 
@jponte, you have just to add this URL:
https://github.com/pantomax/hassio-addons
in the hassio add-ons, save and then you should see a new list of addons

Thanks. Itās installed.
Do I need something special to send the signals to my RF devices?
I have this:
switch
- platform: rpi_rf
gpio: 17
switches:
estores_sala_baixo:
pulselength: 711
protocol: 5
code_on: 8388608
code_off: 133742
But I think I shouldnāt use a switch, because I just want to send the signal I donāt need to have the button ON.
You could use a script or a scene if you want only 1 button
Installation/Build of Dasher killed my hass docker instanceā¦ Had to restart it via console but after that dasher was installed to hass! Created my config via SSH and launched docker, works great. Thanks Amazon for the free Buttons!

Glad you got it working OK.
Thanks for the feedback.
RTL is only a receiver since it uses hardware that was originally designed to receive TV signals.
It can listen for 433mhz sensors but there is no capability to transmit.
You need to look for another solution if you need to control 433 devices.
Hi,
i am not able to install it, if I press install dasher, nothing happens, thats not true, it looks like its trying to install but then no luck.
Its clean current hassio install on a ubuntu server 16.04 instance.
All other add ons (appdeamon, samba, Mosquitto broker, Check Home Assistant configuration and Homebridge) are working fine.
Any ideas ?
Regards

Weird. Whats in the hassio logs? (from hassio advanced menu)
