[PROBLEM] An action works no more
**Describe the problem**
I have a problem with the plugin since yesterday.... have configured 3 actions on my Harmony:

1. cinema - turns on a media player, A/V receiver & TV.
2. Netflix - turns on the TV and launches the Netflix app.
3. eintertain - turns on the TV & Telekom Receiver

Since yesterday action 3 does not work reliably - when I start this action on the Harmony remote control the message appears that the action is started but very often only the TV is switched on - when ending the action the same, sometimes only the TV is switched off! I have tested extensively and the Telekom receiver is mostly only at the 2nd or 3rd execute the action on or off!

If I start the action on the Harmony remote everything works - both devices are switched on and when switching off the same! 

Actions 1+2 work fine - I have powered down the receiver & Harmony Hub and restarted Homebridge with no success! Since this has never happened since I use the plugin and also only one action is affected by it, I'm pretty clueless what the reason can be...


**To Reproduce**
I switched on Entertain and the TV manually, activated the Homebridge Debug Log and switched off action 3 - works, the Telekom receiver and the TV are switched off! Then I turned on action 3 - only the TV is turned on, the telecom receiver remains off.
