What air quality sensors do you recommend?

Any sensor that reports through Home Assistant, MQTT, or a direct API works with your agent. Look for sensors that measure at least CO2 and PM2.5 for a good baseline. Multi-sensor devices that also report VOCs, humidity, and temperature give you the most complete picture.

How often do the sensors update?

Most air quality sensors report every 30 seconds to 5 minutes depending on the model. Your agent reads these updates in real time, so alert notifications are sent within seconds of a threshold being crossed. You do not need to configure polling intervals on the agent side.

Can I use outdoor air quality data as well?

Yes. You can connect outdoor air quality sensors or use public air quality APIs through Home Assistant. Your agent can compare indoor and outdoor readings to help you decide when opening windows will improve or worsen your indoor air quality.

Air Quality Monitoring: Indoor Environment Tracking

Track CO2, particulate matter, humidity, and VOCs through your OpenClaw agent with real-time alerts and ventilation automation.

What You Will Get

By the end of this guide, your OpenClaw agent will monitor your indoor air quality around the clock. You will ask "how is the air quality in the bedroom" and receive readings for CO2, PM2.5, humidity, temperature, and volatile organic compounds. Your agent presents the data in plain language, telling you whether conditions are good, moderate, or need attention.

Real-time alerts keep you informed when any reading crosses a threshold you set. If CO2 rises above 1000 ppm in your office because the windows have been closed all day, your agent notifies you and can suggest or trigger ventilation actions automatically.

Historical tracking shows you trends over days and weeks. You can ask for a weekly air quality summary and see how conditions change with cooking, cleaning, weather, and occupancy patterns. This data helps you make informed decisions about ventilation, air purifiers, and daily habits.

Step-by-Step Setup

Connect your air quality sensors and configure monitoring through OpenClaw on RunTheAgent.

Connect Your Air Quality Sensors

Open the Integrations panel and add your air quality monitoring devices. Common sensors report through Home Assistant, MQTT, or direct APIs. Add each sensor and specify which metrics it reports, such as CO2, PM2.5, PM10, humidity, temperature, or VOCs.

Assign Room Locations

Map each sensor to a room so your agent can respond to location-specific queries. Say "the air sensor in the living room is called living room air" and repeat for each room. This lets you ask "what is the CO2 in the office" and get the right reading.

Test Real-Time Queries

Ask your agent about current conditions. Try "what is the air quality right now" for a whole-home summary or "what is the PM2.5 in the kitchen" for a specific reading. Verify the numbers match what your sensor hardware displays. Test several rooms to confirm all sensors are reporting correctly.

Set Alert Thresholds

Define limits for each metric. Tell your agent "alert me if CO2 goes above 1000 ppm" or "notify me if humidity drops below 30%." You can set different thresholds per room if certain areas need tighter monitoring. Your agent sends notifications through your preferred channel when any threshold is crossed.

Configure Ventilation Automation

Connect ventilation devices like exhaust fans, whole-house fans, or smart vents. Tell your agent to activate ventilation when air quality degrades, for example, "turn on the office fan when CO2 exceeds 900 ppm and turn it off when it drops below 600." This creates an automatic feedback loop.

Enable Historical Tracking

Turn on data logging so your agent stores readings over time. Ask for trends like "show me the CO2 trend for the bedroom over the past week" or "when was humidity highest in the bathroom this month." Historical data is essential for understanding patterns and making lasting improvements.

Schedule Regular Summaries

Tell your agent to send daily or weekly air quality summaries. Say "send me a daily air quality report at 8 AM." The summary includes average readings per room, any threshold breaches, and comparisons to previous periods so you can track improvement over time.

Tips and Best Practices

Place Sensors at Breathing Height

Mount air quality sensors at the height where you breathe, typically 3 to 5 feet from the floor. Avoid placing them directly next to windows, doors, or HVAC vents, as those locations do not represent the air you actually breathe in the room.

Correlate with Activities

Ask your agent to compare air quality readings with times of day. You will likely see PM2.5 spike during cooking and CO2 rise during sleep hours in the bedroom. These correlations help you target ventilation improvements where they matter most.

Combine with Thermostat Data

Cross-reference air quality with temperature and HVAC activity. Sometimes poor air quality results from running the HVAC in recirculation mode for too long without fresh air intake. Your agent can highlight these connections in your summaries.
