Once a DOOR Hub is online, day-to-day operation is light: it runs continuously and carries traffic between DOOR Smart Home devices and the DOOR cloud. This article covers what you do after install — adding new devices that connect through the Hub, removing them, reading the Hub's status lights, changing its WiFi, and how firmware updates work.
About this feature
DOOR Smart Home devices do not pair to the Hub one-by-one the way some smart home systems require. Each device is added to the DOOR App by scanning its QR code, and it then joins the private DOOR wireless network the Hub provides — automatically, with no separate "inclusion" or pairing mode on the Hub. The Hub just needs to be online and within wireless range (open-air range is more than 300 meters). For sites where some devices sit beyond range, add another Hub to extend coverage.
Before you start
- The Hub is installed and shows Online in the DOOR App.
- You are signed in to the DOOR App with Device Management permissions.
- The Unit the device belongs to already exists in DOOR OS (otherwise the device is added at the building level and won't appear under the resident's unit in Devices → Controls).
Adding a device that connects through the Hub
- Open the DOOR App and select the property.
- Tap Devices, then Add a device.
- Scan the device's QR code. If you can't scan it, choose the option to enter the serial number. Important: scanning or capturing the QR code is required — don't physically install a device before adding it in the app.
- Follow the in-app instructions. Assign the device to the correct Unit so it shows up for that resident (a device left at the building level appears under the building, not inside a unit).
- Confirm the device reports Online once it joins the Hub's network.
Removing a device
To take a device off the property:
- In the DOOR App, open the device's page.
- Open Settings.
- Tap Delete Device and confirm.
The device stops reporting through the Hub. Removing a device does not affect the Hub or the other devices on the network.
Reading the Hub's status lights
The Hub has three labeled indicator lights — PWR, Internet, and Cellular:
| Light | State | Meaning |
|---|---|---|
| PWR | Green, flashing quickly | Starting up |
| PWR | Green, solid | Powered on |
| PWR | Red, flashing slowly | Updating (firmware) |
| PWR | Red, flashing quickly | Restoring to factory defaults |
| PWR | Red, solid | Device error |
| Internet | Blue, solid | Connected to the internet |
| Internet | Blue, flashing slowly | WiFi hotspot mode |
| Internet | Blue, flashing quickly | WiFi settings changing |
| Cellular | Green, solid | 4G cellular is on |
| Cellular | Green, flashing | LTE registered, but no network |
The Ethernet jack also has small lights: green = connected to the router/switch; fast-blinking yellow = normal data; slow-blinking yellow = no response from the router; off = something is wrong.
Firmware updates
Hub firmware updates are managed by DOOR. While an update runs, the PWR LED flashes red slowly; let it finish — don't power the Hub off mid-update. The DOOR App's Hub page shows the current firmware version under the device's technical information.
If it didn't work
- A new device won't come online — confirm the Hub itself is Online, and that the device is within the Hub's wireless range. Move the device closer or add a Hub. See DOOR Hub troubleshooting.
- The device isn't under the resident's unit in Devices → Controls — it was likely added at the building level (building-level devices appear at the end of the units list, not inside a unit). Confirm it's assigned to the resident's Unit.
