Aeon 4in1
The Aeon 4-in-1 multi-sensor is supported in firmware versions over 1.1.1280. It appears as 4 devices: a motion sensor, a light sensor, a humidity sensor, and a temp sensor.
To include the sensor, choose Add Device on your MIOS system, and then tap the black button by the battery compartment. Once it appears in your system, if it is not yet configured, hold the black button for 3 seconds and release. This causes the sensor to wake up so it can be configured, at which point it will appear as 4 devices.
Once the sensor is configured, you can hold the black button for 3 seconds again to force it to wake up so it can be polled for the temperature, humidity, light level, and motion sensor trip status. Note that it will only be polled once every 10 minutes to conserve the batteries. To force a poll on the next wakeup click the 'Poll Now' button on the MIOS dashboard for the motion sensor device.
