## 🖥️ Control Center: Check Device, Printer and Network Status

Open Control Center to check every printer, every registered device and your app version at a glance, plus network health from the sidebar.

### 📝 Steps
1. In the left sidebar, tap the **Device List** icon (installed app only, not the web version) to open **Control Center**.
2. At the top, **System Current** shows your version, followed by **Upgrade Available** or **No Upgrade Available**; tap **Upgrade Now** if one is offered.
3. The **Printer** row shows a tile per configured printer, in the color for its **online** or **offline** status.
4. The **Device** row shows a tile per registered device, labelled **Main Device** or **Sub Device**; your current device carries a small badge icon.
5. Tap **Refresh In (Ns)** to reload at once — it also refreshes on its own every 5 seconds while Control Center is open.

### 📝 Check network status
1. Tap the network icon at the bottom of the sidebar (installed app only) for **Offline**, **Poor Network**, **Moderate Network** or **Healthy Network**, plus **Latency** and **Bandwidth** when you're online.
2. The app version also shows on the **Login** screen as **Version {number}**.

> **💡 Tip:** A **Poor Network** alert pops up on its own. Dismiss it and it stays quiet for 24 hours, even if the network is still poor.
