Alexa and executing script also with command TURN OFF

I’ve integrated Alexa with HA with haaska. All ok.
Then i’ve integrated Xiaomi Universal IR Remote to HA and i’ve create a script to turn on the TV in my scripts.yaml

alias: Television
- service: remote.send_command
entity_id: ‘remote.xiaomi_mi_universal_remote’
data: {“command”:“xxxxxx”}

The data sent is same to turn on or off the tv…

So, to power on or power off then TV, i’ve always to say: “Alexa, turn ON Television”.

If I try “Alexa, turn OFF Television”, alexa can’t find a device named Television.
How can I execute same script with the command “Alexa, TURN OFF …” ?Any demo code?Thanks
