Appearance
The OLED Screen
The unit has a small OLED screen that shows a connectivity status bar across the top, plus one of several screens below it depending on what the unit is doing.
The status bar
The status bar appears along the top row of almost every screen and shows four icon pairs, left to right: WiFi, 4G/LTE, Ethernet, and Cloud (MQTT).
What each icon means
Each network icon (WiFi / 4G / Ethernet) is followed by a small tick or cross:
| Icon pair | Meaning |
|---|---|
| WiFi + tick | WiFi is connected and has an address |
| WiFi + cross | WiFi is not connected |
| 4G/LTE + tick | The cellular connection is up and has an address |
| 4G/LTE + cross | The cellular connection is not up |
| Ethernet + tick | Ethernet is connected and has an address |
| Ethernet + cross | Ethernet is not connected |
The Cloud icon (last in the row) shows the state of the unit's connection to CoppelBox's cloud:
| Icon | Meaning |
|---|---|
| Ethernet / WiFi / 4G icon, highlighted | Connected to the cloud — the highlighted icon shows which network it's using |
| Cross | Not connected to the cloud |
| "S" | Waiting for the unit's clock to sync before it can connect securely |
| Sad face | The unit has no cloud configuration or credentials loaded — this shouldn't appear on a normally provisioned unit |
No alerts or battery status on screen
Alerts and battery/power status are not shown on the OLED — check the CoppelBox dashboard for those. The screen only ever shows connectivity and relay state.
The main screens
| Screen | When you see it | What it shows |
|---|---|---|
| Booting | Briefly, on power-up | "COPPELBOX BOOTING" and the firmware version |
| Relays (home screen) | Normal operation | Status bar + relay numbers 1–6, each highlighted (inverted) when that relay is on |
| Device Info | Press UP from the relay screen | Claim code and MAC address (or PROVISION REQUIRED — see below) |
| Info | Press DOWN from the relay screen | Firmware version and which firmware slot is running; returns to the relay screen after 5 seconds or on any button press |
| WiFi setup | After a short PAUSE press | The temporary setup hotspot's password and network name |
| Webpage | Once a device joins the setup hotspot | The address to open in a browser (192.168.4.1) |
See The Buttons for how to reach the Device Info and Info screens, and for the recovery/reset confirmation screens shown during those gestures.
The PROVISION REQUIRED screen
Units ship already registered to the CoppelBox cloud, so a working unit should boot straight to the relay screen. PROVISION REQUIRED appears on the Device Info screen only if the unit has no cloud identity yet — this is not a normal state for a unit that has already been set up and used.
If you see PROVISION REQUIRED on a unit that previously worked, or on a brand-new unit straight out of the box, see Troubleshooting and contact support rather than trying to fix it yourself.
