AirCompare™ vs ThermoAlarm

AirCompare™ reduces home energy consumption and saves you money by providing two smart tools, a ventilation controller and a thermostat controller. Both smart controllers can be used “manually” to give you advice on how to best adjust your ventilation and thermostat. AirCompare™ can also be configured to automatically control your HomeKit-enabled windows, fans and thermostats. The AirCompare™ ventilation controller calculates the energy content of your home’s interior air and compares it to the air outside. If you can get free heating or cooling by just opening your windows, AirCompare™ will make it happen! What if rain is coming? AirCompare™ checks your local weather for current and forecasted rain. You can decide how sensitive AirCompare will be to rain in the forecast. For instance, you might choose to leave your windows closed for the night if the chance of rain in the next 8 hours is 30% or more. The AirCompare™ thermostat controller uses your preferences, combined with an analysis of current conditions, to optimize the setting of your thermostat. AirCompare™ uses current electricity rates (where available) and your local weather forecast, along with your preferences, to calculate the ideal setting at any moment. The optimum setting balances your comfort against the expected cost of heating or cooling. For instance you might choose to tolerate a higher summer temperature when electricity rates are peaking, and enjoy a cooler temperature when electricity is less expensive late at night. You might turn off your A/C if you know a cold front is due soon. AirCompare™ simplifies your life by considering all the data and making these complex decisions for you.

Weather Alarm lets you set alarms that only go off when specific temperature conditions are met. Instead of waking up and checking the forecast, let the forecast wake you up. How it works: Set a temperature condition — above, below, or between a range — pick a location and a time window, and Weather Alarm handles the rest. When the temperature hits your threshold during your chosen window, you get alerted.
