To achieve customization and energy saving on settings, Advanced Settings feature is introduced for users to customize some other settings for their meo maxi.
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
- Measurement Interval
→ how frequent environment is measured
Example: If 10 minutes is selected, meo maxi monitor will measure every 10 minutes.
Also see “Sending interval”
- 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 maxi will send the stored measurements at the end of the 6 hours.
- 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. - Settings update interval
→ how frequent the setting changes are updated on meo maxi monitor.
Example: If 12 hours is selected, any changes of the advanced settings are updated within the next 12 hours. - Reboot interval
→ how frequent the meo maxi monitor reboots
Example: If 1 day is selected, the monitor will reboot every day.
Auto settings are the default settings for all meo maxi at the factory. Based on the power mode you are using, meo maxi has different advanced settings. The purpose is to extend the operating time when the monitor is battery-powered.
Advanced Settings | Auto | |
USB-powered | Battery-powered | |
Measurement interval | 3 mins | 5 mins |
Sending interval | 1 hour | 6 hours |
CO2 event threshold | 500 ppm | 800 ppm |
Settings update interval | 1 hour | 24 hours |
Reboot interval | 1 day | 7 days |
Opening hours
- Opening hours
→ Opening hours of your organisation. This impacts dashboard visualisation (Covid Risk (CO2) and exposure calculation). Only data within opening hours will be used for exposure calculation and the Covid Risk (CO2) 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 (Covid Risk (CO2) and all exposure calculation). - Time zone
→ define the time zone where you place the meo maxi - Holidays country
→ define the holiday of your meo maxi. This impacts dashboard visualisation (Covid Risk (CO2) and exposure calculation).
Alerting is designed to notify users based on the alert rules. meo has two default alert rules:
- CO2 is above 800 ppm
- 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.
Mandatory Configuration:









That’s it. The Alerting is now configured.
Additional configuration:
Changing language to French:








Repeat Step 1 to Step 8 (except 5) for the other alerts rules.
Changing threshold of the CO2 alert rule:








Changing duration of the alert:
To change the duration of the alert, please kindly go through the following concepts.
- Evaluation interval time: How often the alert will be evaluated
- 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,







No, meo maxi 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.
meo maxi connects via 4G LTE/M or NB-IoT cellular network. Please make sure that meo maxi is not being covered (especially metal). Place it closer to windows, with cellular network coverage.
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.
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.
Yes, you can customize the Air Quality LED color in the advanced Settings.
Customizing LED intensity (including OFF) is available in the advanced Settings.
Yes, you can use your own USB-C to USB-A cable.
Status LED blinking pink 5 times means your meo maxi is having issue with its firmware. Please contact meo air analytics at cs@meo.life (providing its serial number and date of purchase).
We do not recommend customer to install meo maxi at the ceiling. meo maxi is advised to be installed between 1 meter to 2 meters from the floor, which is the standard human breathing height.
We usually advise our customers to prioritize their locations with several factors.
- Time: the longer the time spent in the room, the higher the priority
- Population: the higher the number of occupants in the room, the higher the priority
- Vulnerability: the higher the number of occupants of children or elderlies, the higher the priority
- Ventilation: the lower the ventilation rate (e.g. with less windows/doors), the higher the priority
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.
No worries, camera is not mandatory in the registration process. You can input manually the 12-character code instead.
