"Ok Google, what is <room name> set to?"
"Ok Google, set <room name> to <temperature>."
"Ok Google, increase/decrease the temperature in <room name> by <number of degrees>."
*Note- If you say "Ok Google, increase/ decrease the temperature in <room name>". This will increase or decrease the temperature by 5 Deg F (3 Deg C).
