Now this is not by any means a permanent solution but I did find better consistency by creating virtual buttons and adding harmony activies mixed with some smarthings actions to turn on when a virtual button is used. Echo thinks it is a switch so it doesn’t have a problem.
Here is a link to create virtual switch:
The only problem with this is the polling. If you turn on the TV with echo but turn it off through a remote smarthings still believes the switch is on. So you would have to manually turn the switch off via mobile app to be able to use the virtual switch.
Now if someone can build a virtual button that can link it’s on/off status with a smarthings added harmony activity, then we may be able have a winner.
