i am trying to send an email whenever the thermostat changes state, i use the following:
the email is sent ok but all i get is:


My new setpoint is {{utilitydevice[245]}} degrees

and not the actual value.. the idx is correct
i also tried but no luck either

You need to construct the message the LUA way. Google is your friend.
Hint, you have to concatenate strings/values like <string> .. <value as string> .. <string>.\
What happens if you print {{utilitydevice[245]}}, what do you see in the log?
