So, the site has this demo: https://wit.ai/getting-started
First two queries it shows are "Turn on the lights" and "Open the door please!" showing how nice the response is.
If you combine them in "Turn on the lights and open the door please!" then the reponse ignores the door part completely:
{
"_text": "Turn on the lights and open the door please!",
"confidence": 0.94,
"intent": "lights",
"entities": {
"on_off": [
{
"value": "on"
}
]
}
}
