During a summer heatwave, keeping your home cool can quickly become a chore. Opening and closing windows, adjusting blinds, managing fans—it’s exhausting. Meanwhile, a basic thermostat runs your A/C all day, even when no one’s around.
With Homey, you can automate your entire cooling strategy. Your devices work together intelligently, keeping your home comfortable while saving energy, so you can relax and enjoy the summer.
Proactive Cooling Before the Heat Strikes
The most effective way to keep your home cool is to prevent it from heating up in the first place. Homey can check the outdoor air temperature each morning. If it predicts a hot day, it can automatically run a “Heat Prevention” Flow. This routine closes your smart blinds on the sunny side of the house early in the morning. This simple action traps the cool overnight air inside and blocks the sun’s intense rays, keeping your home comfortable for hours.

Homey also helps you take advantage of cooler nighttime air. A Flow can monitor the outdoor temperature during the evening. As soon as it drops below your indoor temperature, Homey can send a notification to your phone saying, “It’s cooler outside now. Open the windows to cool down.” This quick reminder helps you air out your home efficiently before you go to sleep.
Intelligent and Efficient Climate Control
Homey makes your air conditioner and fans work smarter, not harder. You can create a Flow that only turns on your A/C when two conditions are met. The indoor temperature must be above your comfort level, and someone must actually be home, based on presence detection. This means you are never wasting energy cooling an empty house.

You can also match your cooling schedule to your energy rates. If you have a dynamic energy contract, Homey can check the electricity price throughout the day. A smart Flow pre-cools your home more aggressively during the cheap, off-peak hours, avoiding the power-hungry A/C during expensive peak times later in the day. This keeps your home comfortable while ensuring you use energy only when the cost is lowest.
When your A/C turns on, a Homey Flow verifies that all your windows are closed by checking your smart window sensors. If a window is left open, it will send you a notification so you don’t waste energy trying to cool the entire neighborhood. The same Flow can also turn on your ceiling fans to a low speed, helping to circulate the cool air more effectively. This makes the room feel comfortable much faster, allowing your A/C to run for less time.
A Cool Welcome Home, Automatically
There’s nothing worse than returning to a hot, stuffy house at the end of the day. Homey can prepare your home for your arrival automatically. When you leave work, a “Going Home” Flow starts to cool things down, ensuring your house is comfortable when you arrive.

This Flow immediately checks the indoor temperature. If it’s too warm, Homey turns on your A/C or a smart fan to begin pre-cooling your main living area. When you walk through the door, your home is already pleasantly cool. It’s the perfect welcome after a day out in the summer heat, without having to waste energy cooling an empty house all day.
