Your thermostat is usually in a hallway—the worst place to measure temperature. When the hallway is "comfy" but your bedroom is freezing, your HVAC fights a war it can't win, costing you
Place three thermometers: one at the thermostat, one in the bedroom, and one in the living room. If the offsets are >3°F, your system is blindly heating/cooling rooms that are already at temperature.
Watch your HVAC turn on and off. If it cycles more than 6 times per hour (short-cycling), it's usually due to a poorly placed thermostat reading a "hot spot" or "cold draft" instead of ambient air.
Feels-like temperature is driven by humidity. If your HVAC only reads Temp but ignores Humidity, you'll keep the AC running just to "feel" cool when a simple dehumidifier would do the trick for 1/10th the cost.
Touch the vents in your furthest room. If they are luke-warm while the hallway is blasting, you have a delivery problem. Closing unused vents can redirect air and stop the HVAC from fighting a losing battle.
One central sensor dictates the climate for 3 different zones, leading to "over-cooling" some rooms while others remain uncomfortable.
Measure the real temp in every occupied room. Calculate the Average Room Temp vs. the Thermostat Temp. The gap is your efficiency bleed.
Move from a single-point sensor to a network of room sensors. Set the HVAC to average the temp or prioritize the room you're actually in.
Three tiers for every budget.
Cheap, accurate, and connected. Map your home's temperature offsets in 10 minutes to find exactly where the HVAC is fighting.
