MH9-CO2-WD CO2 Monitor Air quality detector

This describes the Z-Wave device MH9-CO2-WD, manufactured by McoHome Technology Co., Ltd with the thing type UID of mcohome_mh9co2wd_00_000.

CO2 Monitor Air quality detector

Overview

MCOHome CO2 Monitor is an air quality detector which compatible with Z-Wave technology.

It is mainly used to monitor CO2 concentration in industrial, agricultural, and residence environment, while monitoring the indoor temperature, humidity and VOC (optional) air quality.

Device can be included into any Z-Wave network, and is compatible with any other Z-Wave certified devices.

Inclusion Information

Activate Inclusion/Exclusion mode in the gateway.

When device is powered on, long press K2 can enter interface for inclusion or exclusion of Z-Wave network.

If device has not been included into any Z-Wave network before, “- - -”will display on the screen.

Then press K2 once, “- - -” flashing and device enters into learning mode to get a node ID. If inclusion is success, a node ID will display on the screen. If not, “- - -” will stop flashing in 20 sec.

Exclusion Information

Activate Inclusion/Exclusion mode in the gateway.

When device is powered on, long press K2 can enter interface for inclusion or exclusion of Z-Wave network.

If a node ID displays, it means the device is already in a Z-Wave network.

To press K2 once can remove it from the network. “- - -” displays and press K1 once can return to normal work.

Device Configuration

The following table provides a summary of the configuration parameters available in the MH9-CO2-WD CO2 Monitor Air quality detector. Detailed information on each parameter can be found below.

Parameter Description
1: Notification Threshold CO2 Notification Threshold
1: Notification sends report ever 30s when CO2 value above threshold
2: Gateway report CO2, Temperature and Humidity is reported when changed

1: Notification Threshold

CO2 Notification Threshold

Overview

Sets the CO2 notification threshold for association group 1.

When the detected CO2 value is higher than the setting value, the device will send a (CO2 Detected Event) report to the Group 1. And this report will keep sending every 30 sec until the detected value is lower than the setting value.

Property Value
Configuration ID config_1_2
Data Type INTEGER
Range 1 to 2000
Default Value 1000

1: Notification

sends report ever 30s when CO2 value above threshold

Overview

Group 1 is for “Notification” purpose, which can add up to 5 Node ID. Device works in “Push” mode in “Notification Command Class”.

When the detected CO2 value is higher than the setting value, the device will send a (CO2 Detected Event) report to the Group 1. And this report will keep sending every 30 sec until the detected value is lower than the setting value.

Use “Notification Set” can set this unsolicited report; this function is default as “OFF”.

2: Gateway report

CO2, Temperature and Humidity is reported when changed

Overview

A gateway is suggested to associate with Group 2, which can support only one Node ID. The
gateway can ask for detected data any time. And the device will report to this associated device
(gateway) when detected data changes:
CO2: report when any change ≥50ppm“Multilevel sensor Report (CO2=0x11)”
Temperature: report when any change≥ 0.5 “Multilevel ℃ sensor Report (Temp=0x01)”
Humidity: report when any change≥ 2%“Multilevel sensor Report (Humidity=0x05)’
