Wifi requirements
Frequency band | 2.4 GHz only. The M2 and M3 sensors do not support 5 GHz networks. If your router broadcasts both frequencies under the same name, rename one so the sensor can identify the 2.4 GHz network specifically. |
Security type | WPA2 Personal (standard home network). Not supported: WPA2 Enterprise, WPS configuration, or networks requiring proxy servers. |
IP assingment | DHCP required (enabled by default on all residential routers). Statically assigned IP addresses are not supported. |
Captive portals | Not supported. Networks that require a login page or browser confirmation step (such as hotel or shared building Wi-Fi) will not work. The sensor needs direct network access after joining. |
Ports required | Outbound TCP on port 25500, UDP on port 1993, and HTTPS on port 443. These are open on all standard residential routers. |
VPN | VPNs active on the installing phone can interfere with the Point Configuration setup flow. Disable any VPN before installing. |
Signal strength and battery | A weak Wi-Fi signal increases battery drain; the sensor antenna uses more power to maintain the connection. Place the sensor within reasonable range of the router. See the M3 placement guide for guidance. |
E1 wired Ethernet connection
The E1 Sensor supports both Wi-Fi and wired Ethernet. For installations in buildings with reliable Ethernet infrastructure, such as hotels, student housing, and multifamily properties, a wired connection eliminates Wi-Fi signal issues entirely and is the recommended approach.
Connection type | RJ45 Ethernet port on the E1; connects directly to a network switch or router via a standard Cat5e or Cat6 cable |
PoE support | The E1 supports Power over Ethernet (IEEE 802.3af). A PoE-capable switch or injector powers the device through the same Ethernet cable — no separate power supply needed. |
Speed | 10/100 Mbps |
Wifi still available | The E1 can also connect via 2.4 GHz Wi-Fi if Ethernet is not available. The same requirements as M2/M3 apply. |
Troubleshooting installation
If you are stuck during installation, check these common causes first before contacting support.
M2/M3 Sensor is not charging or not responding
Make sure the sensor is sufficiently charged before starting. A flat battery prevents the sensor from entering setup mode. Charge via USB-C for at least 10 minutes and try again.
M3 Sensor will not enter setup mode (purple light)
Hold the back button for several seconds until the sensor glows purple.
Point Configuration network does not appear in Wi-Fi settings
Confirm the sensor is glowing purple. Disable any VPN on your phone. On iOS, enable Local Network access for the Minut app under Settings → Minut. Try restarting your phone.
Sensor will not connect to Wi-Fi
Confirm you are connecting to a 2.4 GHz network. If your router uses the same name for both 2.4 GHz and 5 GHz, temporarily rename them to distinguish the bands. Confirm no captive portal or enterprise security is in use.
iOS installation troubleshooting
Enable Local Network access
Go to Settings → Minut on your iPhone and make sure Local Network is enabled. Without this, iOS will block the app from finding the Point Configuration network.
Confirm the sensor is in setup mode
Hold the back button until the sensor glows purple. Open your iPhone’s Wi-Fi settings and confirm Point Configuration appears as an available network.
Restart your phone if stuck
iOS can sometimes get into a state where it cannot connect to the Point Configuration network. A full restart of the phone usually resolves this. Put the sensor back into setup mode after restarting and try again.
Android installation troubleshooting
Grant Location permission
The Minut app requires Location access on Android to scan for nearby Wi-Fi networks during installation. Go to Settings → Minut → Permissions → Location and confirm it is enabled. Also ensure that Location Services (device-level) are turned on.
Without Location permission, the app cannot detect the Point Configuration network
Connect to Point Configuration manually if needed
If the automatic connection does not work, go to your phone’s Wi-Fi settings and manually select Point Configuration. Your phone may warn that this network has no internet access; this is correct and expected. Tap Connect anyway, then return to the Minut app using the back arrow.
No internet on Point Configuration is normal; it is only used to pass Wi-Fi credentials to the sensor
Disable VPN and restart the app
If still stuck, disable any active VPN, fully close and reopen the Minut app, put the sensor back into setup mode (purple), and try again.
Sensor offline after installation
If a sensor that was previously working has lost its Wi-Fi connection and isn’t reconnecting automatically, work through these steps in order.
Check the status light
Press the button on the sensor. A green light means it is online. A white then red sequence means it cannot reach the Minut server.
Reboot the router
Turn the router off, wait 20 seconds, then plug it back in. Wait for the router to fully restart before testing the sensor again.
Power cycle the sensor
Remove the sensor from its mounting plate and hold the back button for a few seconds to turn it off. Wait 10 minutes, then turn it back on and press the front button to check its status.
Update Wi-Fi settings via the app
In the Minut app: Properties → select unit → tap the sensor → settings icon (⚙) → Advanced → Update Wi-Fi Settings. Follow the in-app instructions. No data is lost during this process.
Use this step if the router’s Wi-Fi name or password has recently changed
If the issue persists, the sensor may need to be reinstalled or factory reset. Before doing either, see What to do when your sensor turns offline for additional steps.
If a reinstall or factory reset is needed, see Reinstalling and factory resetting the M3 sensor.
Update wifi settings
If your router’s Wi-Fi name or password has changed, you can update the sensor’s Wi-Fi settings without reinstalling it. No data is lost during this process.
Tap Properties → select the rental unit → tap the sensor
Tap the settings icon (⚙) in the top right corner → tap Advanced → tap Update Wi-Fi Settings
Hold the back button on the sensor until it glows purple
Follow the app instructions to connect to the new 2.4 GHz network and enter the new password
All settings and event history are preserved
Known router issues
The following routers are known to cause unusually long connection times or intermittent connectivity issues with Minut sensors. If you have one of these, the sensor may still work; but may take longer than usual to connect during installation.
AVM Fritz!Box 7560
Tilgin HG2381-EU (Bahnhof branded)
Tilgin HG2501-EU (Bahnhof branded)
Netgear Nighthawk R7000
If you have one of these routers and the sensor will not connect after multiple attempts, contact hello@minut.com with your router model and a description of the issue; there may be specific configuration steps that help.
Contact Support
If none of the above has resolved your issue, contact the Minut support team. The more information you include, the faster we can help.
