core: Failed to connect to device (Broadlink RM Mini3)

When will this issue be fixed?

I already had the crypotgraphy lib installed, but I did discover that this is almost certainly caused by v0.11.1 of https://github.com/mjg59/python-broadlink

I was able to find the packets to turn off and on my TV on another HA forum post, and tested that they work through HA without having been learned through broadlink.learn service, which proved that HA could communicate with the device via broadlink.send.

The learn the rest of my IR codes, I downloaded v0.10 of https://github.com/mjg59/python-broadlink (pip3 install broadlink==0.10), and ran the following sequence of command in a python shell:

import broadlink
from base64 import b64encode

devices = broadlink.discover(timeout=5)
devices[0].auth()

devices[0].enter_learning()
# point remote at device to learn code, light will turn off
packet = devices[0].check_data()
b64encode(packet).decode('utf8')

try this: edit components/broadlink/__init__.py #auth = await hass.async_add_executor_job(device.auth) auth = device.auth My tests worked fine

For others reading this to try make sesne of it all here is the break down to its simplest form:

In order to have the broadlink.send and broadlink.learn functions you need to add the following to your configuration.yaml file

switch:
  - platform: broadlink
    host: 192.168.0.x
    mac: 'C8:F7:42:xx:xx:xx'

This is the minimum required to get the broadlink unit configured on HA you can add other info like unit type and friendly name if you want. To learn commands it is easiest to use a windows program called “Broadlink Manager” (you can google it) Once you have learnt commands you can add to the original config and add switches such as TV on and off, please note that having == on the end of the command is vital to it working

switch
  - platform: broadlink
    host: 192.168.0.x
    mac: 'C8:F7:42:xx:xx:xx'
    switches:
      lounge_tv:
        friendly_name: Lounge TV
        command_on: 'JgCSAAABIpIWEhYRFhIWNRsx....(truncated).....FhIWNRYSFjUWEhYRFzUW=='
        command_off: 'JgCSAAABJo4WEhYRFhIWERY....(truncated).....hsMFjYWERYSFhEXERYSGg=='

If you dont want switches but prefer to use a list of commands then add the following to your scripts.yaml file:

'lounge_ac_on':
  alias: Lounge AC On
  sequence:
  - service: broadlink.send
    data:
      host: 192.168.0.x
      packet:
        - "JgCSAWNRc1FhIWAABI....(truncated)....FhEWEhYRFxEWNWERcRFjUXzUWAA0FAAAAAAAA=="

you can also combine commands, to change source on my TV i need to press ‘input’, ‘right’, ‘ok’ this can be lumped together to make things easier:

'tv_change_source':
  alias: Change TV Source   
  sequence:
    - service: broadlink.send
      data:
        host: 192.168.0.x
        packet:
          - "JgBQAAABH5MTEhISFw4TEhISExISEhMSEjcTNhM2EzYTNhM3FQ8TNhMSEzYTEhISEzYTEhMSEhITNhMSEzYWMxMSEjcSNxM2EwAFPwABJkkRAA0FAAAAAAAAAAA="
    - delay:
        milliseconds: 300
    - service: broadlink.send
      data:
        host: 192.168.0.x
        packet:
          - "JgBQAAABIJMTEhISExISEhMSExISEhMSEjcSNxM2EzYTNhM3EhITNhMSEhMSEhM2EzYTEhMSEhITNhM4ETcYDBMSEjcSNxM2FwAFOwABKUYSAA0FAAAAAAAAAAA="
    - delay:
        milliseconds: 300  
    - service: broadlink.send
      data:
        host: 192.168.0.x
        packet:
          - "JgBQAAABIZMTEhMSEhITEhISExISExYOEzYTNhM2FzMSNxI3ExISNxYzEhMSNxISEzYTEhMSEhIXDhI3ExETNxISEzYXMhM3EgAFQAABJEoTAA0FAAAAAAAAAAA="

Massive thanks to @RobHofmann for working out the nitty gritty of it all

Well, here’s what I did:

Download all the files in this directory: https://github.com/home-assistant/home-assistant/tree/dev/homeassistant/components/broadlink

Then create a custom_components folder in the same directory as your configuration.yaml. Create a broadlink folder in the custom_components folder and copy the files from above into this folder. Make the necessary change to __init__.py, restart Home Assistant, and you should be good.

Custom components created from an integration override the existing integration.

My broadlink rm mini 3 also has the same problem, it can only connect locally. It is also on firmware ver. 44057. Does anyone know how to flash the firmware to v55?

Hi guys. I need help to test a possible solution, would you mind?

Steps:

1. Download and run this file.
2. Wait 5 seconds.
3. If you see the learning light on the remote, capture a code.
4. A file called debug.txt will be created.
5. Send me the file.

try this: edit components/broadlink/__init__.py #auth = await hass.async_add_executor_job(device.auth) auth = device.auth My tests worked fine

This worked for me too. Thanks! Would you mind submitting a PR for this @GitforZhangXL?

@emnik I’m using Home Assistant inside Docker. After jump to /bin/bash of Home Assistant (docker exec -it home-assistant /bin/bash), my __init__.py file is in: /usr/src/homeassistant/homeassistant/components/broadlink/__init__.py

Having installed home assistant in virtualenv, there is no auth = await hass.async_add_executor_job(device.auth) in components/broadlink/__init__.py There is an auth function but nothing like the above in it… The Failed to connect still here… (the broadlink lib version is 0.11.1)

I just tested it. Using the broadlink manager to learn the commands, I got it to work.

The sending of the commands works like a charm.

Here is my config:

- platform: broadlink
  host: 192.168.0.123
  mac: 'a8:f7:f2:6e:fe:81'
  type: 'rm_mini'
  friendly_name: 'Broadlink RM 3 Mini Bedroom'
  switches:
    tv_lift_bedroom:
      friendly_name: TV Lift
      command_on: 'JgAsAQADiJ6anpkABOwAA4yemp6ZAAdhAAOMnpmemgAE6wADjZ6Zn5kAB2AAA4yemZ+ZAATrAAOOnZqemQAHXwADjp2anpkABOsAA4+dmZ6aAAdfAAOOnZqemQAE6wADjZ6anpkAB18AA4+dmaGXAATrAAONnpmemgAHXwADjZ6anpoABOoAA4+cmp6ZAAdhAAOMn5iemgAE7AADjJ6ZnpoAB2EAA4yemZ6ZAATwAAOLnpeemQAHYQADjJ6ZnpoABOsAA46dmZ6aAAdfAAONnpqemQAE7QADjpyZnpkAB2AAA46dmZ6aAATrAAOPnJqdmgAHYAADjpyanpkABOwAA46cmp6ZAAdhAAOMnpmemgAE7AADjJ6anpkAB2AAA4yemp6ZAATsAAONnpmemQANBQAAAAAAAAAAAAAAAA=='
      command_off: 'JgAwAAAEH5+YAAE/mQADqwAEJp2YAAE/mQAGIQAEJJ6YAAFAmAADrAAEI5+ZAAE/mAANBQAAAAAAAAAA=='

PS. Don’t forget to add the “==” at the end of the commands. This got me searching for a while.
