Can my AI check the current temperature and moisture in my grain silo?

Yes! First use `get_devices` to find the device ID for your silo sensors. Then use `get_temperature` and `get_moisture` with that device ID to get current readings. Temperature above 25°C or moisture above 15% may indicate spoilage risk. For historical trends, use `get_device_telemetry` with keys=temperature,moisture to see how conditions have changed over time.

How do I detect early signs of grain spoilage using CO2 levels?

Use the `get_co2` tool to check CO2 readings from headspace sensors in your bins. Elevated CO2 levels (above 1500 ppm) indicate biological activity from mold, insects, or grain respiration — often appearing days before temperature changes. Combine with `get_alarms` to check for any active spoilage alerts. If CO2 is rising, consider turning on aeration using `set_relay_state` to ventilate the bin and reduce spoilage risk.

Can I remotely control my aeration fans based on sensor readings?

Yes! Use the `set_relay_state` tool with your device ID, relay name (e.g., "fan", "aeration"), and desired state (true for ON, false for OFF). Before activating, check current conditions with `get_temperature` and `get_moisture`, and verify weather conditions with `get_weather` to ensure outdoor conditions are suitable for aeration. For example, avoid running aeration during high humidity or rain.
