Xiaomi Chuangmi_ir (Universal IR Remote Controller)

hangy · August 29, 2017, 3:09pm

hi to all and sorry for my bad english…

I’m trying to make work with homeassistant the xiaomi universal ir remote controller (https://www.gearbest.com/smart-home/pp_229556.html)

i’ve found this plugin: https://github.com/homeassistantchina/custom_components

i’ve extracted the token using my rooted phone using this procedure: https://github.com/homeassistantchina/custom_components/blob/master/doc/chuang_mi_ir_remote.md

in the switch part of my configuration file i’ve added:

platform: chuangmi_ir
name: “livingroomirremote”
host: !secret chuangmi_ip
token: !secret chuangmi_key
timeout: 20
switches:
reciever:
command_on: ‘’
command_off: ‘’

as the guide says in the service menu of homeassistant i used the learn_command_ipaddress to learn my remote code… but nothing appears… and watching my logs i can see this:

@syssi

Alright. As next step please enable the debug logging for the custcom component:

logger:
  default: warn
  logs:
    custom_components.switch.chuangmi_ir: debug

And try again. Please post your home-assistant.log.

syssi · August 29, 2017, 3:49pm

My first impression: Your device isn’t available. It’s possible to ping the device (ping 192.168.1.189)?

hangy · August 30, 2017, 5:33am

Yes… I’ve two of them. Both are pingable… When i came back from work i’ll add the logger component and post the output. Thanks

hangy · August 30, 2017, 3:17pm

@syssi this is the output when i try to learn a remote:

Is your chuangmi_key hexadecimal and has a length of 32 characters?

hangy · August 30, 2017, 4:15pm

is hex and the length is 33 char

syssi · August 30, 2017, 4:22pm

Are you sure? Put the cursor in front of the last char.

hangy · August 30, 2017, 4:59pm

sorry, i’m a stupid… all of them are 32 chars

syssi · August 30, 2017, 6:36pm

@ec-blaster Can you help here? I know you are using the device: Xiaomi mi wifi plug & air purifier - #125 by ec-blaster

I think changing the timeout doesn’t help because the timeout is used at L71 and the code fails at L68 already.

@hangy Could you try to change the following line:

github.com

SchumyHao/python-miio/blob/ee0294b39c26d1cc2e6a3c2caa9fe0d4e76b8681/miio/miio.py#L21


      
          class device:
              """Main class representing the miio device."""
              def __init__(self, ip, token, debug=0):
                  self.ip = ip
                  self.port = 54321
                  self.token = bytes.fromhex(token)
                  self.debug = debug
          
                  # TODO this is a mess, find a nicer way to provide token to construct
                  Utils.token = self.token
                  self._timeout = 5
                  self.__id = 0
                  self._devtype = None
                  self._serial = None
                  self._ts = None
                  self._ts_server = int(time.mktime(datetime.datetime.utcnow().timetuple()))
          
              def __enter__(self):
                  """Does a discover to fetch the devtype and serial."""
                  m = device.discover(self.ip)
                  if m is not None:

Increase the timeout a bit (10 seconds?) for testing. This timeout is applied here and later used at L128. The implementation and used library is pretty old… I will try to rewrite the component this weekend.

syssi · August 30, 2017, 7:17pm

I’ve fixed some issues. Please give it a try:

The code looks a bit unstable because of timing issues.

it works… the learning method… tomorrow i’ll try to fully integrate

thankssssssssss

hangy · August 30, 2017, 10:44pm

ok i’ve tryed to send a packet and it works perfect

ec-blaster · August 30, 2017, 11:02pm

Sorry, I didn’t get the thread notification until late night, although I see that you solved it.
I am using the same component by SchumiHao, and I got that error only twice: once when I hadn’t set the timeout parameter and another time that I couldn’t understand why. I solved this last one by rebooting my router.

virualdo · September 3, 2017, 5:54pm

i have tried this and learn_command works perfect, but when i try to send_command i get this error:

i have checked that the ip and token was right.

Any suggestion?

thanks

syssi · September 3, 2017, 6:22pm

It looks like you hit this bug, too:

virualdo · September 3, 2017, 7:16pm

thanks, i’ve tried this commands before
miio --ip 1.2.3.4 --token 1653
mirobo --ip 1.2.3.4 --token 1653
with errors

After your response i’ve tried
“miio --control 1.2.3.4 --token 1653 --method miIO.info" and gives me this error
Error: no such option: --control
but
"mirobo --ip 1.2.3.4 --token 1653 -d info” gives me this

can i try something more? thanks

syssi · September 3, 2017, 7:49pm

If the following command just works

mirobo --ip 1.2.3.4 --token 165xxx3 -d info

the ir_play command should also work:

mirobo --ip 1.2.3.4 --token 165xxx3 -d raw_command miIO.ir_play '["freq":"38400","code":"your-captured-command"]'

Please give it a try.

virualdo · September 3, 2017, 10:40pm

Yes, it works with that command. I’ve replaced [] to {} to make it work.
Now, back in homeassistant, when i try to send this same captured command, the blue led flashed several times and then it turned off. I’ve must to reset manually the chuangmi_ir to make it be usable again.

i’ve updated the python-miio and python-mirobo to version 0.0.11 and 0.1.4.

Thanks-
