    Advanced Settings

    To achieve customization and energy saving on settings, Advanced Settings feature is introduced for users to customize some other settings for their meo mini.

    Note: Advanced settings are only available to admin only

    Colors (applies to monitor only)

    Define 4 different colors for the Air Quality LED at 3 different CO2 ppm level

    Energy savings

    1. Measurement Interval
      → how frequent environment is measured
      Example: If 10 minutes is selected, meo mini monitor will measure every 10 minutes.

      Also see “Sending interval”
    1. Sending interval
      → how frequent the measured data is sent to meo cloud, in absence of CO2 event. This impacts dashboard visualisation (in absence of CO2 event)
      Example: If 6 hours is selected, without any CO2 events within that period, meo mini will send the stored measurements at the end of the 6 hours.
    1. CO2 event threshold
      → the minimum CO2 concentration that forces sending, ignoring the Sending interval.
      Example: If 800 ppm is selected, as soon as CO2 level gets above 800 ppm, all previously stored data are sent to meo cloud. While CO2 is above 800 ppm, the Sending interval will be ignored, and only Measurement interval will prevail.
    2. Settings update interval
      → how frequent the setting changes are updated on meo mini monitor.
      Example: If 12 hours is selected, any changes of the advanced settings are updated within the next 12 hours.
    3. Reboot interval
      → how frequent the meo mini monitor reboots
      Example: If 1 day is selected, the monitor will reboot every day.

    Auto settings are the default settings for all meo mini at the factory. Based on the power mode you are using, meo mini has different advanced settings. The purpose is to extend the operating  time when the monitor is battery-powered.

    Measurement interval3 mins10 mins
    Sending interval1 hour6 hours
    CO2 event threshold800 ppm1500 ppm
    Settings update interval1 hour24 hours
    Reboot interval1 day7 days

    Opening hours

    1. Opening hours
      → Opening hours of your organisation. This impacts dashboard visualisation (Viral Risk and exposure calculation). Only data within opening hours will be used for exposure calculation and the Viral Risk visualisation.

      Example: If your organisation opens from 8:30am to 4:30pm, you can just fill in the first two timeboxes, deleting the third and the fourth, like below:

      If your organisation opens from 8:30am to 6:00pm and has a mid-day break from 12:00pm to 2:00 pm, you can fill in all the four timeboxes, like below:

      Note: Data between 12:00pm to 2:00 pm will not be shown in dashboards (Viral Risk and all exposure calculation).
    2. Time zone
      → define the time zone where you place the meo mini
    3. Holidays country
      → define the holiday of your meo mini. This impacts dashboard visualisation (Viral Risk and exposure calculation).
    Alerting

    Alerting is designed to notify users based on the alert rules. meo has two default alert rules: 

    1. CO2 is above 800 ppm
    2. monitor(s) cannot send data (i.e. disconnected or low network coverage).

    The alerts will work only for the monitor(s) added to the organization and with the Mandatory Configuration completed. Furthermore, Additional Configuration is available: changing language to French, change CO2 threshold, change evaluation duration.

    Note: If you haven’t added any monitors, please move to the “ Activation” tab.

    Changing duration of the alert:

    To change the duration of the alert, please kindly go through the following concepts.

    1. Evaluation interval time: How often the alert will be evaluated
    2. Evaluation lasting time: Once condition is breached, alert will go into pending state. If it is pending for longer than this time, an alert will be sent.

    By default, the Evaluation interval time and Evaluation lasting time of the CO2 > 800 alert rule are 2 minutes and 10 minutes respectively. This indicates that the system will evaluate whether the CO2 is above 800 ppm every 2 minutes. Once the CO2 is above 800 ppm for the next 10 minutes, then an alert will be sent.

    As for the “No data” alert rule, the Evaluation interval time and Evaluation lasting time are 10 minutes and 7 hours respectively. 

    To change the duration of the alert rule,

    Demand control ventilation

    Only for meo mini X and meo maxi, to control your HVAC / VAV ventilation system or inform your BMS through wire communication:

    • configure CO2, S2, S3 and S-In on app.meo.life settings page.
    • unscrew the back plate to access the wire connectors.
    • power with 0-24V line.
    • “S-In” is an optional ventilation system feedback.
    • Ground line of the ventilation system should also be connected to the ground connector (Black).
    FAQ
    Monitor
    Can I put my own standard SIM into the monitor?

    No, meo mini only support LTE/M or NB-IoT SIM.
    If you would like to use your own LTE/M or NB-IoT service provider, please contact meo air analytics at cs@meo.life to check compatibility.

    Why my meo mini does not connect well?

    meo mini connects via 4G LTE/M or NB-IoT cellular network. Please make sure that meo mini is not being covered (especially metal). Place it closer to windows, with cellular network coverage.

    Can I use meo mini in outdoor environment?

    Yes, only if it is under a shelter (protected from rain and excess dust).
    If you have doubt about it, please contact meo air analytics at cs@meo.life for advice.

    How long does the SIM card last for?

    Embedded SIM card last up to 3 years upon fair use (i.e. Auto for all parameters in advanced settings). The lasting period depends on various factors such as (but not limited to) “Sending interval”, “CO2 event threshold”, “Settings update interval”, “Reboot interval”.
    The lower the number, the higher data usage, implying burning data faster than expected, thus reducing time of usage with remaining data.

    Can I customize the LED color?

    Yes, you can customize the Air Quality LED color in the advanced Settings.

    Can I turn off the Air Quality LED?

    To turn off the Air Quality LED, you need to set the colors to Black on all thresholds.

    I inserted the Batteries into meo mini but it does not work, why?

    Please check if the batteries position is correct or try with other new batteries.

    I found the provided power cable too short. Can I use my own one?

    Yes, you can use your own USB-C to USB-A cable.

    Does meo mini measure PM (Particular matters) or VOC (Volatile organic compounds)?

    No, meo mini measures exclusively CO2, Temperature and Humidity with 2 dedicated sensors. Please refer to the datasheet to know more. If you want PM and VOC as well, meo maxi is what you are looking for .

    Can I install meo mini at the ceiling?

    We do not recommend customer to install meo mini at the ceiling. meo mini is advised to be installed between 1 meter to 2 meters from the floor, which is the standard human breathing height.

    I have 40 rooms in a school, but I only have 10 meo mini monitors due to limited budget. How do I allocate the monitors?

    We usually advise our customers to prioritize their locations with several factors.

    1. Time: the longer the time spent in the room, the higher the priority
    2. Population: the higher the number of occupants in the room, the higher the priority
    3. Vulnerability: the higher the number of occupants of children or elderlies, the higher the priority
    4. Ventilation: the lower the ventilation rate (e.g. with less windows/doors), the higher the priority
    How should I use the Move function in the settings? Can I buy only 1 meo mini and move it to different rooms every day?

    The idea of the Move function is for customers to move monitors to new areas for which they have more interest. We do not recommend our customers to move the monitor in a very short time as a prolonged observation gives a comprehensive understanding of the area. And circulating the monitor prevents you from comparing different locations under the same condition.

    Is meo mini using NDIR CO2 sensor?

    meo mini is using the NDIR sensor technology implemented by Sensirion under PASens®.

    Activation
    If I don’t have a camera on my desktop, how can I scan the QR code on the Monitor Activation Card?

    No worries, camera is not mandatory in the registration process. You can input manually the 12-character code instead.
