Pass color and brightness parameters using TRIGGERcmd Smart Home Alexa skill

Russ

Thanks to @tuicemen's suggestion, now you can use commands that accept brightness or color as a parameter via the TRIGGERcmd Smart Home Alexa skill.

Brightness will be a number from 1 to 100.
Color will be red, blue, brown, green, pink, purple etc.

To test it, you could enable parameters on your notepad command like this:

Then say something like: "Alexa, turn notepad red"

I'll look into adding on Google Assistant too, but so far this only works with the TRIGGERcmd Smart Home Alexa skill.

Alexa devices for existing commands (created before 2/6/2022) will need to be deleted and re-discovered, or you can change the command's name and change it back so it will be re-created with the new color and brightness properties.

Just awesome!
For the Dim commands you can say something like "Alexa, office light 50%" or "Alexa set office light to 50"
This should allow control of other things that rely on a number value as well.
You can say Dim in a Alexa call but brighten doesn't seem to work Alexa says OK but nothing happens. (at least not in my tests)

Awesome, looking forward to this to be implemented for Google Home too, can't wait!

Russ

@javier-rilova-0, this works on Google Home now too. Please try it.

Did it stop working? I used this to control my computer volume, and I think since yesterday it isnt working anymore, even after deleting the devices

Russ

@moacir-vilela-sêga , not that I know of. Are you using the Google Assistant or Alexa?

Are you using a script? If so can you paste it here?

Do you have parameters enabled on the command?

Is your script logging the parameter? If you run the script manually with a number parameter does it work?

@russ I am using Alexa. I did a simple python script

import pyttsx3
import threading
import sys
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume, IAudioEndpointVolumeCallback
from comtypes import CLSCTX_ALL, COMObject

from ctypes import POINTER, cast

class fala:
    def __init__(self,msg,voice=0):
        threading.Thread(target=self.thread,args=(msg,voice,)).start()
    def thread(self,msg,voice):
        tts = _TTS(voice)
        tts.start(msg)
        del(tts)
    
class _TTS:
    engine = None
    rate = None
    def __init__(self,voice):
        self.engine = pyttsx3.init()
        self.engine.setProperty('volume',1.0)
        voices = self.engine.getProperty('voices')
        self.engine.setProperty('voice', voices[voice].id)
    def start(self,text_):
        self.engine.say(text_)
        try:
            self.engine.runAndWait()
        except:
            fala(text_)


class AudioEndpointVolumeCallback(COMObject):
    _com_interfaces_ = [IAudioEndpointVolumeCallback]

    def OnNotify(self, pNotify):
        print('OnNotify callback')

list2 = sys.argv[1:]
devices = AudioUtilities.GetSpeakers()
interface = devices.Activate(IAudioEndpointVolume._iid_, CLSCTX_ALL, None)
volume = cast(interface, POINTER(IAudioEndpointVolume))
callback = AudioEndpointVolumeCallback()
volume.RegisterControlChangeNotify(callback)



try:
    if isinstance(int(sys.argv[1]),int):
        fala('volume definido para ' + str(int(sys.argv[1])))
        volume.SetMasterVolumeLevelScalar(int(sys.argv[1])/100,None)
except:
    fala(' '.join(list2))

So if I say a number it changes the volume, but if I say a color or "Turn on/off" it says On, Off or the Color. (Basically it tries to say it out loud if the parameter is not a number)

Now, it only works during On and Off. All the colors or the numbers are not working as valid parameters.

This is how it is coded in TriggerCMD currently:

 {
  "trigger": "Protocolo",
  "command": "python \"D:\\Programming\\Python\\teste vozes.py\"",
  "offCommand": "",
  "ground": "foreground",
  "voice": "Protocolo",
  "voiceReply": "",
  "allowParams": "true"
 }

Russ

@moacir-vilela-sêga , will you please try this simpler script that just prints and logs the first parameter?

import os, sys

f = open(os.path.dirname(os.path.realpath(__file__)) + "\log.txt", "a")
msg = "first arg is " + sys.argv[1] + "\n"
print(msg)
f.write(msg)
f.close()

Also, please try running your script from a cmd prompt with red or 80 as the parameter to see if it's erroring. I wonder if it's erroring and you're just not seeing the output so you don't see the error.

@russ I dont know what to tell you now. It is just working normally now. I didn't change neither my script nor tried to re-add the device.
I decided to test it before changing to your script and it worked.

Russ

@moacir-vilela-sêga , strange. I don't know what fixed it either.
