LUA script: Turn Plug ON and play alarm sound with OmxPlayer

[gemminiss]

Hello all!

I want to make a LUA time script that turns-On a Zwave smartplug for 20secons, and plays one alarm sound twice

But it does not work as expected.

If I leave the smartplug = 'On' and exceute the scritp, it plays well the sound twice every minute
Only leaving the (commandArray['Powerplug'] = "On FOR 20 SECONDS', it works well, plug ON 20secons every minute

And If I put all together, the plug turns ON (but more than 20 seconds) but it does not play any sound. However I can see in the log, that the output of the .mp3 (bitrate, etc) has been printed.

for information: I use the assert+read+close, to be sure the execution of the io.popen is finished before playing the second sound.

Does anyone knows whats happening? another way around?

Code: Select all

commandArray = {}

commandArray['Powerplug'] = "On FOR 20 SECONDS"

local file = assert(io.popen('omxplayer --vol -1500 /home/pi/MyHDD/AlarmSounds/GarageOpen.mp3'))
local output = file:read('*all')
file:close()
print(output) 
  
local file2 = assert(io.popen('omxplayer --vol -1500 /home/pi/MyHDD/AlarmSounds/GarageOpen.mp3'))
local output2 = file2:read('*all')
file2:close()
print(output2) 

return commandArray

Thanks for your support!

Hi gemminiss,

if you run your posted script, the plug isn't on and has no power in the moment you start the alarm sound!

The commandArray-Command is executed when you reach the "return". A possible way is to power on the plug via curl and the Json-API before you start the sound.
