How to Maintain the Badge
In this guide you will learn how to replace the battery inside the Badge and keep it working properly.
3 min task
What
The Badge registers when a caregiver is near a room with a Nobi light. It shows who entered a room, when, and for how long. This makes care moments visible and helps improve daily support.
Why
The Badge makes it clear when and where care was given. It helps teams work better together and reduces the need for manual reporting.

If the Badge stops responding or no longer shows a caregiver’s presence, the battery might need to be replaced. Replacing it quickly avoids missing important care information.
Detailed steps
Changing the batteries in the Nobi Badge.
1. Locate the a small notch on the bottom edge of the badge.
2. Using a flat plastic tool like a guitar pick, insert the plastic pick into the notch and gently pry until you hear two clicks. (NOTE: Do not use a metal tool or screwdriver—this can damage the casing.)
3. Slide the pick along the edge. You’ll hear more clicks as more of the casing loosens. Continue sliding the pick around the edges until all sides are open.
4. Inside the Badge, remove the CR3032 lithium 3V battery and insert a new one. Make sure the battery is placed in the correct direction.
5. Line up both halves of the Badge and press firmly around the edges until all sides click back together.

How to Perform a Factory Reset via Light
Learn how to reset a Nobi light to factory settings using the built-in button—without using Bluetooth or the app.
3 min task
What
A factory reset clears the light's settings and removes its link to the current room and housing unit. Typically, this is done via Bluetooth and the Nobi app. But if the light is unresponsive or Bluetooth connection fails, you can now reset the light directly through the hardware—available on generation 2.1 and newer.
Why
Factory resetting a light before moving it ensures the system no longer tracks or monitors it in the old housing unit. If you skip this step, the light may still be registered in its previous location, which can disrupt reporting and monitoring in the new room.

This new method gives you a backup option when Bluetooth doesn’t work or when the app can’t connect—so you can still safely prepare the light for removal or reinstallation.

Detailed Steps
Locate the small hole on the top side of the light, facing the ceiling. This is where the reset button is built in. Refer to the image for guidance.
1. Use a thin object like an unfolded paperclip to gently press into the hole until you feel the button inside.
2. Hold the button down for three seconds.
3. The light will turn blue and say: “Factory reset completed.”
4. A few seconds later, the light will start blinking blue. This means it’s ready to be installed again.
You have successfully factory reset the light.

Requirements Firewall
What

To ensure stable communication, Nobi lights need access to specific internet ports. These firewall settings make sure the light can send and receive essential data.

Why

Nobi lights rely entirely on their network connection to detect falls, trigger alerts, and receive software updates. If the required ports are blocked, communication with the cloud, time synchronization, or even audio calls may fail.

Requirements

For uninterrupted performance, these firewall ports must be open:

# Cloud connection

*.nobi.cloud and nobi.cloud: port 443 (TCP)

*.nobi.cloud: port 5671 (TCP)

# NTP (time sync)

time1.google.com, time2.google.com, time3.google.com, time4.google.com: port 123 (UDP)

# Debugging

*.nobi.cloud: port 2222 (TCP)

# SIP signalling

nobi.sip.us1.twilio.com: port 5060 (TCP + UDP)

nobi.sip.us1.twilio.com: port 5061 (TCP)

# SIP media

168.86.128.0/18: port range 10,000–60,000 (UDP)

# Software updates

hosted.mender.io: port 443 (TCP)

s3.amazonaws.com: port 443 (TCP)

c271964d41749feb10da762816c952ee.r2.cloudflarestorage.com: port 443 (TCP)

For the firewall ports the following should be added:

sentry.io port 443

*.sentry.io port 443

DHCP needs to be active on the Wifi network. Nobi lights always gets their IP address via DHCP. If required, fixed IP addresses can be given via DHCP reservation.

Without these settings, Nobi may not function as expected—alerts could be delayed, updates might fail, or the light may lose cloud connection.

Troubleshooting

Make sure no login or proxy stands in the way of a direct internet connection

Run a firewall check if your light doesn’t seem to connect or update correctly

How to Factory Reset a Nobi(ta) Light
In this article, we’ll walk you through the process of factory resetting a light.
5 min task
What
To relocate your Nobi or Nobita light to a different housing unit, you need to perform a factory reset first. This resets the light to its original settings, allowing you to install it in a new location. The reset is conducted via Bluetooth, so you'll need a mobile device with the Nobi app installed. Make sure you're standing right under the light you wish to reset.
A factory reset does two things: it returns the light to its default settings and removes the room in the housing unit it was previously linked to. After this, you’re ready to physically remove the light.
Why
It’s important to factory reset a light before you remove it from the housing unit. If you don’t do this, the light will still register that it’s located in the old housing unit. Therefore, no reports or monitoring from this new housing unit would be reliable.
For more information on relocating a light, read How to Remove and Move a Nobi Light.

Factory resetting a light
In order to start, you need to be signed in into the Nobi app on a mobile device with bluetooth enabled. Also, make sure you’re standing right underneath the light you wish to factory reset.
Detailed steps
1. From the dashboard, click the three lines in the top left to open the navigation menu.
2. Go to Housing units in the left menu of the application.
3. Choose the housing unit with the light you wish to reset and click edit.
4. Go to the Rooms tab.
5. Locate the room with the light you wish to reset. Click on the three dots below.
6. Choose edit device.
7. Click on Factory reset.
8. Nobi will ask for confirmation, click Reset.
9. You will be presented with an overview to find the light. Choose the one with the best connection (providing you’re standing directly underneath the light).
  
  How to find the best connection:
  - You will see signal strength bars indicating the strength of the bluetooth connection. Choose the light with the highest connection.
  - Regardless, you will also see the hardware code for each light. Knowing the hardware code makes it easy to select the right light.
10. A red banner will confirm the reset has started. After approximately one minute, you will receive an audible message directly from the light that it has been successfully reset. The light will now flash light blue.
11. Once the light flashes blue, we are ready to disassemble the light.
You have now successfully factory reset the light.

Onboarding Error Codes

During the onboarding process, the Nobi light may return specific error codes. Each error code indicates where the onboarding failed and what type of issue occurred.

What

This article provides an overview of onboarding error codes that can occur when setting up a Nobi light. Each error code represents a specific failure during the onboarding process and includes a short explanation of its cause. In most cases, users should contact support for assistance.

Why

Understanding onboarding error codes helps internal teams quickly determine whether an issue is caused by user input, network configuration, device state, or a system-level problem.
This allows support teams to troubleshoot more efficiently and decide when an issue needs escalation to Nobi.

Onboarding Error Codes Overview

Error code	Error description	Explanation
Error 10	Unknown error in the current step	If you see this error message, it's best to perform a power cycle of the light and then try to onboard again. If the problem persists, contact Nobi.
Error 11	Timeout in the current step	This indicates that some part of the onboarding took too long. This can be caused by issues with the network or any other temporary issue. Try again and if the problem persists, contact Nobi.
Error 12	Failed to parse the OnboardEvent. Note that there will be no steps in the result in this case	This means that the message coming from the phone was not understood by the Nobi light. Contact Nobi.
Error 13	Failed to send the amp request to verify the staging device	This means there's a problem with the communication to the cloud. Possibly a network issue related to port 5671. Please check the firewall setting with the IT department. All details about the firewall setting can be found in the appliance sheets.
Error 14	Received an error from the cloud	The light connected properly to the cloud and sent its information, but the cloud failed to finalize the onboarding.
Error 15	The reset code is invalid ( only possible if password present on device )	The light is not in onboarding mode, or is not linked to this account (during network update).
Error 16	Primary was set to false, but no primary_device was given	Same as error 12: bad message from phone to light. Contact Nobi.
Error 17	WIFI was part of the setup, but no WIFI credentials given	Same as error 12: bad message from phone to light. Contact Nobi.
Error 19	No staging device was given	Same as error 12: bad message from phone to light. Contact Nobi.
Error 20	Failed to connect to the given cloud host	The light successfully connected to WIFI but then couldn't connect to the Nobi cloud on port 5671. Check if any firewall rules are preventing that connection (see also Error 13)
Error 100	We were unable to setup the current step due to incorrect credentials.	The entered WIFI and/or password is incorrect. Make sure you take into account capital letters and punctuation marks. If a guest network is being used, this is only possible if no confirmation is required on the web page (It is not recommended to use any guest networks, as this is less safe, and also of lower quality)
Error 101	We got no IP address for the current step	This means that the light successfully connected to the WIFI but never received an IP address from the DHCP server. Check if the DHCP range is properly configured and not exhausted.
Error 102	We were unable to connect to the internet in the current step	This means that the light successfully connected to the WIFI but was unable to check its internet connection. The light checks that it has internet access by doing a HTTP GET to https://nobi.cloud

This concludes possible alerts you may face when onboarding a Nobi light.
