HA integration render and others.

[kuduacz]

I am using home assistant and integrate Moode (on my pri4) by mid integration. It work well but I don't know what render is in use. 
I mean when Moode playing something by airplay from my iPhone or by bluetooth from my wife's smartphone I don't see it in home assistant.
So I try to do something like that:

add new sensors in my HA:

1.    - platform: command_line
   
2.      name: Moode Renderer
   
3.      command: curl http://moode.local/currentsong.txt | sed -n 's/^file=//p'
   
4.      value_template: >-
   
5.        {% if value == 'Airplay Active' %}
   
6.        Airplay
   
7.        {% elif value == 'Bluetooth Active' %}
   
8.        Bluetooth
   
9.        {% elif value == '' %}
   
10.        Brak
    
11.        {% else %}
    
12.        MPD
    
13.        {% endif %}
    
14.      scan_interval: 15
    
15.  
    
16.    - platform: command_line
    
17.      name: Moode MPD State
    
18.      command: curl http://moode.local/currentsong.txt | sed -n 's/^state=//p'
    
19.      value_template: >-
    
20.        {% if value == 'play' %}
    
21.        Play
    
22.        {% elif value == 'pause' %}
    
23.        Pause
    
24.        {% elif value == 'stop' %}
    
25.        Stop
    
26.        {% else %}
    
27.        Brak
    
    
28.        {% endif %}
    
29.      scan_interval: 15
    Enable metadata file in setting in Moode.try to link that file by sudo ln /var/local/www/currentsong.txt /var/www/currentsong.txt
    

And here starts problem.
At 1st try I linked file in/var/www/ doesn't change when I change render in Moode. I mean. I play something by airplay, and see that in "Moode.local/currentsong.txt".
When I change course to some internet radio file doesn't changed. so render sensor is useless.
When I try to link file with -sfn parameters in command it work well but file disappear after few hours.

Anyone can help me ?
I just won't to know what is playing on my Moode audio in my home assistant, because deflate integration does not support that feature.
