Gateways
ReMoni’s gateways enable wireless data communication between ReCalc and ReMoni sensors, with some models also supporting indoor climate monitoring or data collection through wM-Bus. Gateways allow Over-the-Air updates of sensors and settings, connect up to 500 sensors each, and automatically distribute signals when multiple gateways are used. All gateways connect via WiFi or SIM card for reliable connectivity.
Gateway Comfort

Gateway Comfort for communicating data between sensors and ReCalc as well as tracking comfort temperatures.
As all ReMoni’s gateways, Gateway Comfort can be used to communicate data collected from ReMoni’s sensors to ReCalc platform and parameter settings from the platform to the sensors. Additionally, the gateway can track temperature and its changes in the room, presented in ReCalc cloud platform.
Features
- Transmits measuring data to ReCalc platform by using WiFi or mobile data.
- Tracks temperature levels in the room.
- Can receive data from up to 500 sensors.
- Sleek and discreet design.
- Easy and quick installation.


Use cases
Ideal for collecting data about temperature and its changes.
- Documenting comfort temperature: Gateway Comfort can used to document the comfort temperature and identify any temperature changes or inconsistencies in e.g. offices and school buildings etc. The temperature data can also be used to better understand building operations or the impact of control strategies on HVAC.

FAQ
How can I be sure that there is connection between the Gateway and ReCalc?
In ReCalc, select Gateway in the sidebar menu and look in the “Connections” column, it should say “Online”.
Bad internet connection?
WiFi
If the Gateway can’t connect due to poor, slow, weak or unstable WiFi the sensor data is stored locally on the Gateway.
When the WiFi connection is re-established, the Gateway starts uploading the stored data to ReCalc.
The Gateway will keep trying to reconnect to a previously used WiFi connection until it is successful. If the Gateway is manually rebooted (by disconnecting the power supply), and the WiFi connection is still offline when it reboots, the Gateway will be configurable to a new WiFi within the next 30 minutes.
Modem
If the Gateway can’t connect due to poor, slow, weak or unstable mobile coverage the sensor data is stored locally on the Gateway.
When the mobile connection is re-established, the Gateway starts uploading the stored data to ReCalc.
The Gateway will keep trying to reconnect to the mobile network. Ensure that the Gateway has good mobile coverage. To test the mobile connection a relocation of the Gateway to an area with good mobile coverage can reveal if the mobile connection actually works or not.
How do I connect the Gateway to a different WiFi?
When you have chosen to connect your Gateway to a specific WiFi network (SSID), it’s not possible to connect to a different network, as long as the current WiFi is visible for the Gateway.
If you wish to connect to a different WiFi network, simply follow these 4 steps:
- Turn off the WiFi, that the Gateway is connected to – for example the router or modem with WiFi connection – or go somewhere, where the current WiFi isn’t reachable and therefore not visible to the Gateway.
- Make sure that the Gateway is not connected to the internet.
- Make sure that the WiFi you wish to connect to is visible to the Gateway.
- Restart the Gateway and run the setup as described in the manual.
You can find the manual in the download section.
Data usage on the gateway
We have 3 main areas that use data on the gateway:
1. The gateway itself
2. Sensors
3. Security updates
The data is used for security updates, communication between Gateway and the Cloud (ReCalc), time synchronization and data exchange.
A typical consumption will be around 20-50 Mb / month.
Average number of sensors | Total Mb/month |
10 | 25 |
50 | 120 |
100 | 235 |
300 | 680 |
500 | 1100 |
Which connection to ReCalc is the best: Modem or WiFi?
It depends on the availability at the location of the gateway.
Any 3G/4G Mobile Data connection or WiFi will do the job since ReMoni sensors do not use much data. Our sensors have no minimum requirement of upload speed either.
How to find your Gateway & Sensor ID
To register a sensor on the ReCalc portal the sensor ID must be used.

Gateway Air

Gateway Air helps with data communication and monitoring indoor climate.
The most important feature of Gateway Air, besides data communication, is its ability to track air quality, focusing on temperature, CO2 levels and relative humidity. Based on these measures Gateway Air can monitor overall indoor climate.
Features
- Transmits data to ReCalc platform by using WiFi or mobile data.
- Equipped with sensor package that measures the air’s content of CO2 (ppm), humidity (%), and temperature.
- Communicates data and parameter settings between ReCalc and ReMoni’s sensors.
- Can receive data from up to 500 sensors.
- Sleek and discreet design.
- Easy and quick installation.


Use cases
Ideal for tracking and ensuring quality of air comfort temperature in the room, by tracking CO2 levels, hmidity and temperature.
- Documenting indoor climate: the gateway can help measure and document the indoor climate at selected locations within the building.
- Temperature variation in rooms: the gateway provides continuos data collection on selected rooms' temperature and its variations.
- Analyze and optimize building operations: With additional data on the indoor climate gathered with the Gateway Air, the impact of changes in control strategies and modifications to systems like HVAC can be observed.
