The WTH (Wireless Temperature Hub) is a dedicated monitoring display: it shows your temperature channels continuously without menus to page through. The few things you configure are handled either by the hub's physical button or through the LF Audio AuralSync app over Bluetooth. This article explains where each setting lives.
Where Settings Live
| Where | What You Control |
|---|---|
| On the hub (physical button) | Restart the hub |
| In the AuralSync app (over Bluetooth) | Name the hub, provide WiFi for firmware updates, and start over-the-air updates |
| Automatic (no setting needed) | Sensor detection, temperature display, and the color scale |
On-Hub Controls
The hub keeps on-device controls deliberately simple, since it is meant to be mounted and glanced at rather than operated.
The Physical Button
- Restart: press and hold the button for about two seconds to restart the hub. It resumes monitoring on power-up.
Status Light
The hub has a status light that shows it is powered and running.
App Settings (AuralSync)
Pair the hub with the LF Audio AuralSync app over Bluetooth (see First Boot and Pairing) to configure the following:
| Setting | Description |
|---|---|
| Device Name | Give the hub a recognizable name so it is easy to identify in the app |
| WiFi for Updates | Provide the name and password of a 2.4 GHz WiFi network with internet access. The hub uses these details to download firmware updates. See Firmware Updates. |
| Start Firmware Update | Begin an over-the-air update from the app |
The WiFi network you provide in the app is used only for firmware updates. The hub does not need WiFi for normal monitoring or for the app connection, which are handled locally and over Bluetooth.
Temperature Display
The way the hub presents temperatures is fixed and needs no configuration:
- Units: readings are shown in Fahrenheit.
- Color scale: each reading is colored from cool (blue) through a neutral mid-range to warm (orange) and hot (red). See Display and Navigation for the full scale.
- History graphs: each infrared channel automatically scales its trend graph to fit the recent range, so no manual adjustment is needed.
Channels
The hub organizes readings into channels, which are assigned automatically as sensors are detected:
- Infrared channels are numbered IR 1 to IR 4 and appear as tiles in the main area of the screen.
- Contact probe channels appear along the bottom of the screen.
Channels populate on their own when a sensor is connected, and stay blank when nothing is plugged in. There is no manual channel setup: connect a sensor and its channel appears.
Unpairing From a Phone
To disconnect the hub from a phone, remove or forget the WTH in your phone's LF Audio AuralSync app (and, if needed, in your phone's Bluetooth settings). You can then pair it with a different phone. See First Boot and Pairing for the pairing steps.
