Force smartthings multi sensor to report temp on mode change?

I have setup CoRE and I am trying to have it monitor temperatures in two rooms and turn on and off a smart plug which has a heater attached to maintain a temperature. I have night mode set to go off at 10 pm which turns the central gas heater off for the house.

The problem I have is the piston will only activate if the temp is less than 72 and the sensor doesn’t report a temp unless it changes. I would like to force the sensor to report the temp when night mode is engaged.
