RoomHub status light and reset button

What RoomHub's status light colours mean, and how to use the reset button.


Overview

RoomHub has a front-facing status light that shows the device's current state and a recessed reset button for reboots and resets. This page explains both.

Status light

The status light shows what RoomHub is doing at a glance:

Light

Meaning

Solid white

System online, operating normally on the local network

Solid cyan

System online, connected to Pleneo Cloud

Slow white blink

Powering on and initialising

Slow yellow blink

No network detected. Check the cable or switch port

Fast yellow blink

Connected, but no IP address (DHCP unreachable). RoomHub falls back to a link-local address (169.254.x.x) and keeps working

Slow blue blink

Firmware update in progress. Do not power off or disconnect

Slow red blink

Needs attention, for example, high temperature

Solid red

System fault. Check diagnostics or contact Pleneo Support

Reset button

The reset button is recessed; use a pin or paperclip to press it. The action depends on how long you hold it, and the status light shows which action is pending while you hold. Release before the time is up to cancel.

Hold time

Action

Light while holding

What it does

2 to 6 seconds

Reboot

Fast white blink

Restarts RoomHub. No settings are changed

7 to 14 seconds

Network reset

Fast green blink

Clears the static IP and reverts to DHCP. All other settings are kept

15+ seconds

Factory reset

Fast red blink

Resets everything, all configuration, logs, and the Pleneo Cloud link

A press under 1 second does nothing, to prevent accidental activation. The button is disabled during a firmware update.

Note: a factory reset clears everything on the device, including all configuration, logs, and the Pleneo Cloud link. The room will need to be set up again from scratch. Use the network reset instead if you only need to clear a static IP.

In summary

  • The status light shows RoomHub's state: white or cyan for normal operation, yellow for network issues, blue for updates, red for faults

  • Reboot with a 2 to 6 second press, reset the network with 7 to 14 seconds, or factory reset with 15+ seconds

  • A factory reset erases all settings; the network reset clears only the static IP

  • Release the button before the time is up to cancel
