Every WTH keeps a complete record of its own identity, firmware, and wireless link on a single screen. When you are confirming a firmware version, checking why a display keeps dropping, or gathering details before you contact support, this is the screen to open. It is read-only, so nothing here can be changed by mistake.
Opening System Info
Open the diagnostics from the home dashboard:
- On the TEMPERATURES home screen, tap the gear in the top-right corner to open Settings.
- Select the System tab.
The System tab lists the hub's identity, versions, and wireless details, along with the maintenance buttons (Start OTA Update, Force OTA Update, and Reset Settings) covered in other articles. This article focuses on reading the information fields.
System Information Fields
Every row on the System tab tells you something specific about your hub. Use the table below to interpret what you see.
| Field | What it means |
|---|---|
| Model | The product identity of your unit, shown as the Wireless Temperature Hub. |
| Hardware | The hardware revision of your hub, for example 1.0. Useful when a support note applies to a specific revision. |
| Manufactured | The date your hub was built at the factory. |
| Firmware | The firmware version currently running on the hub. New units ship on 4.8.0. Compare this against the latest published version when you check for an update. |
| Sensor board | The firmware version running on the hub's internal sensor board, the part that reads your infrared sensors and probes. It is updated together with the hub during a firmware update, so the two versions normally advance together. |
| Wireless Channel | The channel the hub uses for its own wireless link to LF Audio displays. |
| Frequency | The 2.4 GHz frequency that matches the current wireless channel. |
| Bluetooth PIN | The 6-digit code you enter in the LF Audio AuralSync app when you pair your phone to the hub. |
| Device ID | A short identifier unique to your hub. Support uses this to look up your specific unit. |
| MAC | The hardware network address of your hub. Rarely needed day to day, but occasionally requested by support. |
| Boots | How many times the hub has powered on since it was built. A count that climbs faster than expected can point to power that is briefly dropping out, so check your fuse and wiring if it rises during normal use. |
| Uptime | How long the hub has been running since its last restart. This resets to zero after every reboot or firmware update. |
The Firmware and Sensor board rows are separate versions for two parts of the same hub. If a firmware update finishes but one version looks out of date, restart the hub and re-check. If they still differ, run the update again from the System tab.
Display Signal Strength
The System tab describes the hub itself. To judge how well a wireless display is connected, open the Devices tab instead. Each display in the Paired Displays list shows its type, firmware, connection status, a Signal rating, and a link mode.
The Signal rating is a simple four-step quality read. Use it to decide whether a display needs repositioning.
| Signal | What it means | What to do |
|---|---|---|
| Excellent | Strong, close-range link | Nothing needed. |
| Good | Reliable link with plenty of margin | Nothing needed. |
| Fair | Usable, but may show occasional lag at distance | Reduce distance or clear obstructions if updates start to stutter. |
| Weak | Marginal link that may drop out | Move the hub and display closer together, or check that both antennas are attached and clear of metal. |
Below the Signal rating, each display also reports a link mode:
- Long Range trades raw update speed for reach. The hub falls back to this mode to hold a connection when a display is far away or partly obstructed.
- High Speed prioritizes fast updates and is used when the two devices are close and the signal is strong.
A Weak signal or a Disconnected display both point to the same short checklist: move the two devices closer together, remove obstructions between them, and confirm the external screw-on antenna is fully attached on both the hub and the display. If a display stays Disconnected after that, check that both the hub and the display are on current firmware before you re-pair it from the Devices tab. A display that repeatedly ends up Disconnected and only recovers after a re-pair is the signature of a link fault that a firmware update corrects on both ends. See Firmware Updates and Troubleshooting.
Signal ratings settle after a few seconds. If you have just moved a display or re-attached an antenna, give the reading a moment to update before deciding whether the change helped.
When to Contact Support
Most connection and reading problems are covered in Troubleshooting, and version questions are answered in Firmware Updates. Check those first, since they resolve the common cases without a support ticket.
If you still need help, gather two details from the System tab before you reach out so we can find your unit quickly:
- Device ID, which identifies your specific hub.
- Firmware version, so we know exactly which build you are running.
The Hardware revision and Manufactured date are also worth noting if a support agent asks for them. With those in hand, contact us through Contact Support and describe what you are seeing, including any Signal ratings or channel readings that look wrong.
