# AirVisual Node Binding
![](/logos/airvisualnode.png)
This is an openHAB binding for the AirVisual Node Air Quality Monitor (opens new window) (also known as IQAir AirVisual Pro).
# Supported Things
There is one supported Thing, the "avnode".
# Discovery
Binding will do autodiscovery for AirVisual Node by searching for a host advertised with the NetBIOS name 'AVISUAL-<SerialNumber>'.
All discovered devices will be added to the inbox. Please note you will need to set the Node username and password in the configuration of the newly discovered thing before a connection can be made.
# Binding Configuration
The binding has no configuration options, all configuration is done at Thing level.
# Thing Configuration
The thing has a few configuration parameters:
Parameter | Description |
---|---|
address | Hostname or IP address of the Node |
username | The Node Samba share username. Default is 'airvisual' |
password | The Node Samba share password |
share | (Optional) The Node SMB share name. Default is 'airvisual' |
refresh | (Optional) The time (in seconds) to refresh the Node data. Default is 60, min is 30 |
Required configuration parameters can be obtained by pressing the center button on the Node for "Settings Menu" > "Network" > "Access Node data" tab.
# Channels
The binding supports the following channels:
Channel ID | Item Type | Description |
---|---|---|
co2 | Number:Dimensionless | CO2 level, ppm |
humidity | Number:Dimensionless | Relative humidity, % |
aqi | Number:Dimensionless | Air Quality Index (US) |
pm_25 | Number:Density | PM2.5 level, µg/m³ |
temperature | Number:Temperature | Temperature |
used_memory | Number | Used memory |
timestamp | DateTime | Timestamp |
battery-level | Number | Battery level, % |
signal-strength | Number | Wi-Fi signal strength, 0-4 |
The Node updates measurements data every 5 minutes in active mode and every 15 minutes in power saving mode (screen off).
# Example
# Thing
The preferred way to add AirVisual Node to the openHAB installation is autodiscovery,
but the AirVisual Node also can be configured using .things
file:
airvisualnode:avnode:1a2b3c4 [ address="192.168.1.32", username="airvisual", password="12345", share="airvisual", refresh=60 ]
# Items
Here is an example of items for the AirVisual Node:
Number:Temperature Livingroom_Temperature "Temperature [%.1f %unit%]" <temperature> {channel="airvisualnode:avnode:1a2b3c4:temperature"}
Number:Dimensionless Livingroom_Humidity "Humidity [%d %unit%]" <humidity> {channel="airvisualnode:avnode:1a2b3c4:humidity"}
Number:Dimensionless Livingroom_CO2_Level "CO₂" {channel="airvisualnode:avnode:1a2b3c4:co2"}
Number:Dimensionless Livingroom_Aqi_Level "Air Quality Index" { channel="airvisualnode:avnode:1a2b3c4:aqi" }
Number:Density Livingroom_Pm25_Level "PM2.5 Level" { channel="airvisualnode:avnode:1a2b3c4:pm_25" }
DateTime Livingroom_Aqi_Timestamp "AQI Timestamp [%1$tH:%1$tM]" { channel="airvisualnode:avnode:1a2b3c4:timestamp" }
# Rules
Example rules:
rule "AirVisual Node Temperature Rule"
when
Item Livingroom_Temperature changed
then
if (Livingroom_Temperature.state > 25.0|°C) {
logInfo("avnode.rules", "Temperature is above 25°C")
}
end
rule "AirVisual Node Humidity Rule"
when
Item Livingroom_Humidity changed
then
if (Livingroom_Humidity.state < 35.0|%) {
logInfo("avnode.rules", "Humidity is below 35%")
}
end
rule "AirVisual Node CO₂ Level Rule"
when
Item Livingroom_CO2_Level changed
then
if (Livingroom_CO2_Level.state > 1000.0|"ppm") {
logInfo("avnode.rules", "CO₂ level is above 1000 ppm")
}
end
rule "AirVisual Node PM2.5 Level Rule"
when
Item Livingroom_Pm25_Level changed
then
if (Livingroom_Pm25_Level.state > 25.0|"µg/m³") {
logInfo("avnode.rules", "PM2.5 level is above 25 µg/m³")
}
end
