The Swiss Half fare Card map is the same link for either mountain. It shows that Diavolezza is not covered by the Swiss Half Fare Card.
It's possible that your hotel has a transit pass you could use if you check with them - but it might not cover Diavolezza either.
Here is the webpage with prices for Diavolezza.
