WIFI Requirements

What

Nobi lights need a stable WIFI connection to function properly. This connection is their only way to communicate with the outside world.

Why

WIFI powers everything Nobi does—detecting falls, sending alerts, updating settings, and syncing with care systems. If the connection is weak, unsecured, or unstable, Nobi can't do its job.

 

Requirements 

The following items need to be open outwardly:

# Cloud connection
*.nobi.cloud and nobi.cloud: port 443 (TCP)
*.nobi.cloud: port 5671 (TCP)
 
# NTP
time1.google.com, time2.google.com, time3.google.com, time4.google.com: port 123 (UDP)
 
# Debugging
*.nobi.cloud: port 2222

 

# 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 WiFi - the frequency bands :
  • Nobi gen 1: 802.11b, g (2.4GHz) and ac (5GHz).  802.11n is not supported.
  • Nobi gen 2: 802.11b, g (2.4GHz) and ac, n (5GHz).

  • 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.

  •  

    For the firewall ports the following should be added:

    sentry.io port 443

    *.sentry.io port 443

 

The following types of authentication are possible:

  • Open network
  • WPA Personal
  • WPA Enterprise (only username and password)
  • Please note: that Nobi does not support WIFI connections that require a captive portal.
 
WIFI strength:
-30 db: This is the maximum signal strength. If you have this measurement, you are likely standing right next to the access point.
-50 db: This is considered an excellent signal strength.
-60 db: This is a good signal strength.
-67 db: This is a reliable signal strength. This is the minimum for any online services that require a reliable connection and Wi-Fi signal strength.
-70 db: This is not a strong signal strength. You may be able to check your email.
-80 db: This is an unreliable signal strength. You may be able to connect to your network, but you will not support most online activity.
-90 db: This is a bad signal strength. You are not likely to connect to internet at this level.

When these conditions are met, Nobi stays connected—so care and safety are never out of reach.

Troubleshooting tips

  • Use a WIFI analyzer app to test the signal where the light will hang

  • If the signal is too weak, consider installing a WIFI extender

  • Turn off Band Steering on your router if Nobi struggles to stay connected

  • Note: Nobi does not support WIFI networks that use a captive portal.
    • A captive portal is a network where you must accept terms, log in, or click a confirmation page before getting internet access (for example, hotel or guest WIFI).
    • Nobi lights cannot complete these login or confirmation steps. As a result, they will not be able to connect to the cloud or function correctly on such networks.
