What
We have a script running on SlabPi that plays entrance theme audio when a member enters the space.
It checks if a member is entering on MQTT ,it pauses MPC, plays a song from the folder "themes" that was mounted from Egg with mpg123 and resumes MPC. It needs paho installed. More info about installing paho here: Shutdown Script
The script
#!/usr/bin/env python
#Invict & Niz 2019
import time
import paho.mqtt.client as paho
import json
import os
from mpd import MPDClient
broker="arbiter.vm.nurd.space"
#define callback
def on_message(client, userdata, message):
parsed_json = json.loads(message.payload.decode("utf-8"))
print("received message =",str(message.payload.decode("utf-8")))
print(parsed_json['name'])
mclient = MPDClient() # create client object
mclient.timeout = 10 # network timeout in seconds (floats allowed), default: None
mclient.idletimeout = None # timeout for fetching the result of the idle command is handled seperately, default: None
mclient.connect("slabpi.dhcp.nurd.space", 6600) # connect to localhost:6600
print(mclient.mpd_version) # print the MPD version
mclient.pause(1)
os.system('mpg123 /mnt/mp3/themes/' + parsed_json["name"] + '.mp3')
mclient.pause(0)
mclient.disconnect()
client= paho.Client("themesong")
######Bind function to callback
client.on_message=on_message
#####
print("connecting to broker ",broker)
client.connect(broker)#connect
print("subscribing ")
client.subscribe("space/door/front")#subscribe
client.loop_forever()
Todo
- Debug. Script was running but theme songs did not work anymore. It is possible that MQTT got disconnected, but we do not have logging yet, so it could be something else :p
- Check if mpd is playing.
- Check mpd volume, adjust the themesong to same volume.
