Example AirPurifier - NRCHKB/node-red-contrib-homekit-bridged GitHub Wiki
Characteristics
| Characteristic | Optional/Required | AcceptedValues | Description |
|---|---|---|---|
| Active | Required | {"On":true} or {"On":false} |
Whether the user wants the air purifier "on" or "off" |
| CurrentAirPurifierState | Required | {"On":true} or {"On":false} |
Whether the air purifier is actually "on" "off" or "idle" |
| TargetAirPurifierState | Required | {"TargetAirPurifierState":0} {"TargetAirPurifierState":1} |
Whether the air purifier is manual or automatic mode (manual=0, automatic=1) |
| LockPhysicalControls | Optional | 0, 1 | Displays "child lock" option |
| SwingMode | Optional | 0, 1 | Swing disabled=0, swing enabled=1 |
| RotationSpeed | Optional | 0 - 100 | Percentage of total speed, step value = 1 |
Possible combinations
The display in the Home app on iOS/MacOS depends on the pair of values sent to the Characteristics Active and CurrentAirPurifierState. This table shows each of the 6 possible combinations of these two properties along with what the Home app display will show. In order to have the Home app display properly, it is important to send the correct pair of values to the HomeKit service node.
The node will output {"Active":1} or {"Active":0} when the user switches the purifier on and off. The node will output {"TargetAirPurifierState":0} or {"TargetAirPurifierState":1} when the user changes between Manual and Automatic operation in the Home app. The TargetAirPurifierState property can also be passed into the HomeKit node to dictate when the purifier is in manual or automatic operation mode.
| Active | CurrentAirPurifierState | Home app Shows |
|---|---|---|
{"Active":0} |
{"CurrentAirPurifierState":0} |
Off |
{"Active":0} |
{"CurrentAirPurifierState":1} |
Turning Off |
{"Active":0} |
{"CurrentAirPurifierState":2} |
Turning Off |
{"Active":1} |
{"CurrentAirPurifierState":0} |
Turning On |
{"Active":1} |
{"CurrentAirPurifierState":1} |
Idle |
{"Active":1} |
{"CurrentAirPurifierState":2} |
On |

Simple Air Purifier
This is an example of a simple air purifier item. There are 3 sets of input nodes.
Auto/Manual mode will determine whether the Home app displays that the purifier is in automatic or manual mode. This is set by sending a value of 0 or 1 to TargetAirPurifierState.
Set target state will dictate whether the user wants the purifier to be on or off. This is set by sending a value of 0 or 1 to Active.
Set actual state off/idle/on this will dictate whether the air purifier is actually off, idle, or on. This is set by sending a value of 0, 1, or 2 to CurrentAirPurifierState.
See the table above for a matrix explaining all 6 combinations and what will appear in the Home app.

Full Featured Air Purifier
Requires version 0.6 or better
This air purifier example shows a full-featured air purifier. It has a parent service (purifier) and a child service (filter state). The basic operation is the same as described above, additions are child lock, oscillate, fan speed, and filter status.
