Apollo Automation

Founded in 2023 in Kentucky, Apollo Automation builds advanced multi-sensor devices for the smart home. In a short time, the brand has built a following among tech-savvy users, tinkerers, and DIY enthusiasts.

Apollo Automation believes that every smart device in your home should earn its place. That’s why it focuses on small, discreet sensors that deliver rich data without visual clutter. Unlike traditional motion sensors, Apollo’s presence sensors use mmWave technology to detect even subtle movements, such as breathing. That means your automations are more accurate and won’t miss someone who’s simply sitting still.

The World’s Smallest Presence Multi-Sensors

The Apollo Automation MSR-2 and MTR-1 are the smallest occupancy multi-sensors ever made. The MSR-2 specializes in detecting static human presence, while the MTR-1 focuses on multi-target and zone tracking. The PRO-1 PoE sensor combines both functions. It uses two mmWave sensors simultaneously to deliver accurate static presence detection and zone-based tracking. Power and data are supplied via Power over Ethernet (PoE) or USB.

Besides presence detection, all three devices measure ambient light, UV index, temperature, humidity, and air pressure. Users can also add a high-quality Sensirion CO₂ sensor to monitor indoor carbon dioxide levels, helping to maintain healthy air quality.

Each device features a built-in piezo buzzer and an addressable RGB LED, letting you trigger visual or audible alerts directly from the device. For example, you could have it play the Mission: Impossible theme song when your dishwasher finishes its cycle.

By combining precise presence detection with useful environmental data, Apollo Automation’s sensors offer a compact all-in-one solution. This means you need fewer separate sensors in your home, keeping your space tidy and your automations effective.

Comprehensive Air Quality Monitoring

The Apollo Automation AIR-1 goes beyond basic CO₂ tracking to provide a comprehensive view of your indoor air quality. It continuously gathers data on key environmental factors and makes that data available in Homey for automations, such as triggering an air purifier when pollutant levels rise.

Out of the box, the AIR-1 measures several critical air quality metrics, including various sizes of fine particulate matter (PM1, PM2.5, PM4, PM10), volatile organic compounds (VOCs), and nitrogen oxides (NOx). It also tracks temperature, humidity, and barometric pressure.

For even more advanced monitoring, the AIR-1 can be expanded with optional sensors. One module enables you to track carbon dioxide (CO₂), which is essential for understanding indoor air quality and freshness. Another module enables the detection of additional gases, including carbon monoxide (CO), alcohol, hydrogen (H₂), nitrogen dioxide (NO₂), and ammonia (NH₃).

A Solution for Plant Lovers

If you enjoy caring for plants, the Apollo Automation PLT-1 makes the job easier. This compact sensor monitors key conditions that affect plant health, helping you care for your plants with precision rather than guesswork.

The PLT-1 accurately measures soil moisture, so you’ll know exactly when to water. It also tracks ambient light and temperature, helping you position your plants where they’ll thrive.

Integrated with Homey, the PLT-1 can send smart notifications or trigger automations, such as turning on grow lights or activating a watering system, based on real-time data from your plants. It’s available in two versions: one with a built-in battery and one without.

Apollo Automation Meets Homey

Even the most precise data isn’t worth much unless you use it. Accurate presence detection and environmental insights only become valuable when they actually improve your home.

With Apollo Automation’s sensors connected to Homey, you can turn that data into smart automations. For example, a mmWave presence sensor can gradually brighten the lights when you enter, and dim them when you leave, so you never walk into the dark. It also keeps them on while you’re sitting still, solving the issue of lights turning off when you’re reading or working.

Homey can also automatically switch on an air purifier if CO₂ levels get too high. Or combine data from temperature, humidity, and light sensors to adjust your thermostat and blinds, keeping your home comfortable and energy-efficient throughout the day. Discover the official Apollo Automation app in the Homey App Store to start using their sensors in your Flows.
