can you set the thermostats on a room by room basis so you aren't heating rooms you aren't actively using?

i have electric everything and my biggest bill in the last 12 months was 375 this january in a place double the size of your unit. (that being said, i'm eversource, not national grid).

i keep everything set to 55 during my working hours when i'm not home, then have it automatically crank the rooms i'm typically in up to 71 a little bit before i get home (and weekends).

when i think of it, i'll also turn it down when i go somewhere during times the schedule would normally have the heat on, but i'm not always great about remembering to do this. (at some point i'll probably set up homekit to manage that since my thermostat supports it, but for now just making the schedule in the mysa app was quick and easy)

a good smart thermostat will also be able to tell you how much power you used on heating, so while that's PROBABLY what's driving up your bill, you'd be able to see exactly how much power you used for heat.
