The M2 is a legacy device. The M2 sensor was released in 2018 and discontinued in 2022. It is no longer available for purchase from the Minut store. Existing M2 sensors continue to receive customer support until at least 2029.
If you are looking to expand your monitoring setup, consider the M3, Minut's current sensor.
The M2 sensor is installed in your rental unit via the Minut mobile app. Any team member with access to the unit can complete the installation. This article walks through charging, placement, and the full installation flow.
Considering upgrading to the M3? The M3 is Minut’s current sensor and supports outdoor mode, and additional features. If you’re deploying new sensors, the M3 is recommended.
Before you start
Create a rental unit first: the sensor must be installed into an existing rental unit. If you haven’t created one yet, go to Properties → + in the app.
Have the Wi-Fi password ready: you will need the property’s 2.4 GHz Wi-Fi password during installation. The M2 does not support 5 GHz networks.
Charge the sensor: new sensors are rarely fully charged. Charge before heading to the property.
Make sure the sensor is switched ON: the M2 has a physical power switch on the back. The sensor will not charge or install if the switch is set to OFF.
Charge the sensor
The M2 sensor charges via the Micro-USB port on the back. Charge it fully before installation.
Make sure the power switch on the back is set to ON before charging. The sensor will not charge if the switch is off. A full charge takes approximately 6 hours from empty. A stable green light on the back confirms it is fully charged.
Where to place the sensor
The M2 sensor is for indoor use only. It is not waterproof and will be damaged by moisture or rain. The noise monitoring is also calibrated for indoor environments; wind and outdoor noise produce unreliable readings. For outdoor monitoring, use the M3 sensor in outdoor mode instead.
Charging the sensor
When you receive the Minut sensor it's usually not fully charged, so start out with charging it. From empty to full battery, it takes about 6 hours, though the received sensor's battery should be about half charged. Make sure that the sensor is turned ON when you charge it. The Minut sensor will not charge if the switch is set to OFF
A full charge is indicated with a stable green light on the back.
Once operating, you can choose to have the sensor plugged in with the charger, or operate on the battery. The battery can last for up to a year before charging is needed. You can read more about charging and battery life here.
Install via the mobile app
The app guides you through the full installation. There are two possible Wi-Fi connection flows: the app directs you to the right one automatically based on your phone and network.
Open the rental unit in the app
Tap Properties at the bottom of the screen and select the rental unit you want to install the sensor in. To add a sensor to a unit that already has one, tap the + icon in the Sensors section.
Select Minut M2
Follow the prompts and select Minut M2 from the list of sensor types.
Put the sensor into setup mode
Press and hold the main button (the lens) on the front of the sensor until it glows purple. This puts it into setup mode.
Purple = setup mode. The sensor is ready to connect.
Connect to Point Configuration
Go to your phone’s Wi-Fi settings and connect to the network named Point Configuration. Your phone may warn that this network has no internet access — this is expected and correct. Tap Connect anyway.
On iOS: tap the back arrow or open the Minut app directly after connecting.
On Android: tap the back arrow in your Wi-Fi settings to return to the Minut app.No internet on Point Configuration is normal — it only passes Wi-Fi credentials
Select your Wi-Fi network and connect
Back in the Minut app, select your property’s 2.4 GHz Wi-Fi network from the list, enter the password, and tap Connect.
2.4 GHz only — the M2 does not support 5 GHz networks
Mount the sensor
Once connected, attach the mounting plate to your chosen surface and snap the sensor onto it. Press the front button; a green light confirms the sensor is online and monitoring.
Green = online and monitoring. Installation is complete.
Next steps
Once the sensor is online, complete your setup before the first guest checks in.
Set your noise thresholds: review the default noise preset for this property. A good starting point is 75 dB daytime and 70 dB for quiet hours.
Connect a booking platform: linking Airbnb or your PMS enables automated guest messaging and Presence Detection.
Configure guest messaging: set up the automated messages Minut sends when noise is detected.
Consider Call Assist: 24/7 operator calls for unresolved noise events.
Troubleshooting
The sensor won’t turn on or glow purple: The battery may be depleted. Connect via USB-C and wait a few minutes before trying again. If it still doesn’t respond, try holding the button for 5–10 seconds.
“Point Configuration” network doesn’t appear in my Wi-Fi settings
Make sure the sensor is glowing purple (setup mode). On iOS, check that Local Network access is enabled for Minut under Settings → Minut. Try restarting your phone if the network still doesn’t appear.
Phone warns that Point Configuration has no internet
This is normal and expected; tap Connect anyway. The Point Configuration network is only used to pass Wi-Fi credentials to the sensor. It is not a regular internet connection.
The sensor won’t connect to Wi-Fi
Confirm you are connecting to a 2.4 GHz network — 5 GHz is not supported. If your router broadcasts both frequencies under the same name, rename one so they’re distinguishable. See Wi-Fi and connectivity.
