Can a smart thermostat control my portable dehumidifier?

Not directly. Smart thermostats control whole-home units wired into the HVAC system. For portable dehumidifiers, use a smart plug that triggers based on humidity readings from the thermostat's app or a separate humidity sensor.

What humidity level should I set my thermostat to?

40-45% is ideal year-round. In winter, you may need to lower to 30-35% to prevent window condensation. In summer, keep below 50% to prevent mold. Your thermostat should auto-adjust based on outdoor temperature if it has this feature.
