The serial number starts with e43:. The older version has a serial number that starts with 33:.
What it measures
Section titled “What it measures”| Reading | Unit | Note |
|---|---|---|
| Temperature | °C | |
| Humidity | % | Relative humidity. |
| CO₂ Concentration | ppm | Shows how well the room is ventilated. |
| VOC Index | Volatile organic compounds. Only on the older version 33. |
|
| VOC Raw | The raw value of the VOC sensor. Only on version 33. |
|
| VOC | ppb | Only on version e43. |
| Equiv. CO₂ Concentration | ppm | Calculated from the VOC. Only on version e43. |
| Air Quality Index | Only on version e43. |
|
| PM1.0, PM2.5, PM4.0, PM10.0 | μg/m³ | Particles in the air, by size. |
| PM0.5 count to PM10.0 count | /cm³ | Number of particles, by size. |
| Typ. particle size | μm | The typical size of the particles. |
| Luminosity | lux | |
| Luminosity [IR] | lux | The infrared light. |
| Dew Point | °C | Calculated from temperature and humidity. |
| WBGT (Indoor) | °C | Heat stress index. Calculated from temperature and humidity. |
The app hides a reading that has no data.
Typical uses
Section titled “Typical uses”- Meeting rooms and offices, to know when the room needs fresh air.
- Classrooms.
- Shops, restaurants and gyms.
- Homes, for dust and particles from smoke or cooking.
Installation
Section titled “Installation”- Put the device at the height where people breathe, away from windows, doors and air conditioners.
- Do not put the device in the sun or near a heat source.
- Connect the device to WiFi from the mobile app. See WiFi setup.
In the add-device wizard, select the model of your device. Press and hold the middle button for a few seconds, until the WiFi icon blinks. When the connection icon stays on, the device is connected to the Internet.
Settings
Section titled “Settings”In Settings > Advanced:
- Local temperature offset: a correction of the temperature in °C. The default is 0.5 °C.
- Altitude: the altitude of the site in metres.
- Allow LAN commands: other devices on your local network can control this device. Keep the setting off if you do not need it.
- Force IPv4 (only
e43): the device connects with IPv4 only. - Calibration table: a field correction for temperature, humidity and CO₂. Version
e43also has VOC, Equiv. CO₂ and luminosity. Press Calibrate to fill it in.
On version e43 you can use the button Long Press in a rule.
The general settings of all devices are in device settings.
Recommended rules
Section titled “Recommended rules”The Recommended setups button on the device page suggests:
- An alert when the temperature goes out of range.
- An alert when the humidity goes out of range.
- An alert when the device stops sending data.
You can also make your own rule, for example an alert when the CO₂ stays high. See create a rule and rule examples.
Troubleshooting
Section titled “Troubleshooting”- CO₂ or VOC values look strange in the first days: the sensors adjust themselves over a few days. Make sure that the room gets fresh air at some time, so that the device sees clean air.
- The temperature is a little higher than a thermometer: check the position of the device. See wrong values.
- The device is offline: see device offline.
