Bose Soundtouch control

[MikeF]

When i type ./Bosevolume.py on the command line i get this error...

I assume you've got the correct values for volIdx and url in lines 10 & 11?

Try typing this in a browser:

Code: Select all

http://<domoticz url>:<domoticz port>/json.htm?type=devices&rid=<Domoticz idx of Bose volume>

(substituting your values, of course!).

The result of the command in my browser:

This is my Bosevolume.py script:

Code: Select all

#!/usr/bin/env python

from libsoundtouch import soundtouch_device
from libsoundtouch.utils import Source, Type
from time import sleep
import requests
import json

bose = '192.168.1.5'
volIdx = '77'
url = 'http://192.168.1.36:8080/json.htm?type=devices&rid=' + volIdx
oldStatus = ''

device = soundtouch_device(bose)
device.power_on()

def domoticzread(var):
	response = requests.get(url)
	jsonData = json.loads(response.text)
	result = jsonData['result'][0][var]
	return result

while 1:
	volume = domoticzread('Level')
	status = domoticzread('Status')
	
	if status != oldStatus: 
		#print volume, status
		if status == 'Off':
			device.set_volume(0)
		else:
			# status = 'On' or 'Set Level: 10 %'
			device.set_volume(volume)
	oldStatus = status
	
	sleep(0.2)

[MikeF]

This might be due to issues with the requests module in python. Try this version instead, using urllib:

Code: Select all

#!/usr/bin/env python

from libsoundtouch import soundtouch_device
from libsoundtouch.utils import Source, Type
from time import sleep
import urllib, urllib2
import json

bose = '<bose url>'
volIdx = '<Domoticz idx for volume control>'
url = '<domoticz url>:<port>/json.htm?type=devices&rid=' + volIdx
oldStatus = ''

device = soundtouch_device(bose)
device.power_on()

def domoticzread(var):
	req = urllib2.Request(url)
	resp = urllib2.urlopen(req)
	response = resp.read()
	jsonData = json.loads(response)
	result = jsonData['result'][0][var]
	return result

while 1:
	volume = domoticzread('Level')
	status = domoticzread('Status')
	
	if status != oldStatus: 
		#print volume, status
		if status == 'Off':
			device.set_volume(0)
		else:
			# status = 'On' or 'Set Level: <x> %'
			device.set_volume(volume)
	oldStatus = status
	
	sleep(0.2)

I`ve got the volume slider working with the new script, but had to add the adress of the Bose to the Domoticz whitelist. But unfortunatly the selector switch stopped working now....Domoticz doesn`t give any errors.

Running ./Bose.py on the command line:

Code: Select all

pi@raspberrypi:~/domoticz/scripts/python $ ./Bose.py
Traceback (most recent call last):
  File "./Bose.py", line 17, in <module>
    arg = int(sys.argv[1])
IndexError: list index out of range

However, on the command line the power.on, off and select.source commands are working fine and the Bose soundbar responds immediately

Code: Select all

pi@raspberrypi:~/domoticz/scripts/python $ python
Python 2.7.13 (default, Nov 24 2017, 17:33:09)

>>> from libsoundtouch import soundtouch_device
>>> device = soundtouch_device('192.168.1.5')
>>> device.power_off()
>>> device.power_on()

[MikeF]

If you run Bose.py from the command line, you need to give it an argument (0 - 9), e.g.,

Code: Select all

./Bose.py 1

Don’t know why selector not working though.

[Furiousz23]

Don`t ask how.....but it was working for a few seconds

Deleted some lines from the script (The select URL part), saved the script. Chmod 0777 and Chmod +x the file....and it was working .
But it doesn`t anymore, this thing i driving me nuts . The strage thing is, after a reboot of the Pi the selector works again, but only one time

[MikeF]

I’m out of ideas - sorry!

[Furiousz23]

No problem, thanx for the help!!

[najtram]

Tried multiple ways.

- selector works from terminal.
- selector gives error in log from domoticz.

From this post (http://www.domoticz.com/forum/viewtopic.php?t=16206) it seams to be the issue that it is an python2 script instead of python3.

Hopefully this helps to find solutions.

[MikeF]

Yes, it's a python 2 script, and it works OK for me.

[MikeF]

@Furiousz23,

Out of interest, what happens if you use an on / off switch, and assign two of the selector switch actions to the switch on / off actions? e.g.,

Code: Select all

On: script:///<path to python script>.Bose.py 2

Also, have you checked that the script has the same owner as Domoticz (e.g., pi:pi)?

[Furiousz23]

Thing is drving me crazy . I got it working for a few seconds.

Deleted the old selector script and created 5 new scripts. Each script with only one action

Power off:

Code: Select all

#!/usr/bin/env python

from libsoundtouch import soundtouch_device
from libsoundtouch.utils import Source, Type
device = soundtouch_device('192.168.1.5')
device.power_off()

AUX:

Code: Select all

#!/usr/bin/env python

from libsoundtouch import soundtouch_device
from libsoundtouch.utils import Source, Type
device = soundtouch_device('192.168.1.5')
device.select_source_aux()

Preset:

Code: Select all

#!/usr/bin/env python

from libsoundtouch import soundtouch_device
from libsoundtouch.utils import Source, Type
device = soundtouch_device('192.168.1.5')
presets = device.presets()
device.select_preset(presets[0])

After that i did some browsing and after 5 minutes i returened to Domoticz and the selector stopped working but without any errors.....

[najtram]

Ok, this took me a lot of time in the meanwhile. I'm so happy if it's going to work. I got a almost running situation, but just not that last step.

What worked was entering presets from command line terminal. Works fine! What doesn't work is entering this script in a switch in domoticz. Somehow I understood, while browsing the forum, that Domoticz is using Python3 instead of Python2. (not sure if this is correct but I needed to continue testing)
So here is what I did:

- Python2 bose.py 2 = WORKING from commandline, NOT in domoticz.
- Python3 bose.py 3 = NOT working from commandline
- Translated script to Python3 script with http://www.pythonconverter.com/
- Python3 bose.py 3 = NOT working from commandline gives error for soundtouch libs.
- Installed pip3
- Loaded soundtouch libs in pip3
- Python3 bose.py 3 = WORKING from commandline
- So with this working Python3 situation, I returned to Domoticz, almost sure that this was the solution.
- BUT back in Domoticz NOT working, giving 256 error in the log.

So for Python2 AND for Python3 it works from my commandline, but not from Domoticz

Used notation in Domoticz:
script:///home/pi/domoticz/scripts/python/bose.py 1
and
script://python/bose.py 6

Script is owned by pi and chmod with +x

Result in log:
Error: Error executing script command (/home/pi/domoticz/scripts/python/bose.py). returned: 256

Thanks for thinking along! Hope someone has a solution!

[MikeF]

I’m sorry this seems to be causing so much trouble!

I’m on v3.8153, so don’t know if this makes a difference. Also, I’m definitely running this as a Python 2 script.

Have you tried my earlier suggestion of running this as a simple on / off switch, to see if selector is the problem? (set up on & off actions).

I’m away at the moment, so can’t test this further.

[najtram]

You don't have to apology! I'm glad you take the time to think along, and thankfull I've gotten this far already!

I've tried in a on/off switch. Same result/error.

[najtram]

I've got it working!!!

I'll post solution later

[najtram]

I did multiple things so i'm not sure what solved it exactly but here's what I did:

I found a similair issue on this site: https://easydomoticz.com/forum/viewtopi ... 2&start=20

There they did a pip reinstall or something like that, so I did:
sudo -H pip install libsoundtouch
sudo -H pip3 install libsoundtouch

I added this on top of the python bose.py:

Code: Select all

#!/usr/bin/python
# -*- coding: utf-8 -*-

Created a bose_sh.sh with the following content:

Code: Select all

!/bin/bash

python3 /home/pi/domoticz/scripts/python/bose.py $1

And put this in domoticz switch:

Code: Select all

script:///bin/bash /home/pi/domoticz/scripts/python/bose_sh.sh 4

[MikeF]

I've just got round to upgrading to v4.9700 of Domoticz, and have hit the same problem - I seem to recall that recent versions of Domoticz only like python3.x, whereas my script was running happily under python2.7.

I can confirm that the bash solution described by @najtram works for me too - thanks!

[MikeF]

I've come up with an alternative solution for controlling Bose volume: instead of using a python script which runs continuously:

Code: Select all

while 1:
	...
	sleep(0.2)

and reads the json from the device to check for a change of volume, I've created a simple lua script which passes the volume value to an equally simple python script.

Lua script:

Code: Select all

-- Set Bose volume

-- change next line to match name of your Bose volume device in Domoticz
local bose = 'Bose volume'

-- change next line to match location of your python script; keep space at end
local py_script = 'python3 /home/pi/devices/bose_vol.py '

commandArray = {}

if devicechanged[bose] then
	boseVolume = otherdevices_svalues[bose]
	cmd = py_script .. boseVolume
	os.execute(cmd)
end

return commandArray

Python script:

Code: Select all

#!/usr/bin/env python3

from libsoundtouch import soundtouch_device
from libsoundtouch.utils import Source, Type
import sys

volume = int(sys.argv[1])

# change next line to match url of your Bose
bose = '192.168.0.69'

device = soundtouch_device(bose)
device.power_on()

device.set_volume(volume)

I believe this is a more responsive approach, and better integrated with Domoticz.

Edit: I left out the second import from libsoundtouch in the last script - now added.

Hi,

I tried to connect to Soundtouch. I get this error:
