METEOTIME DUO, NEXUS and SINUS weather stations

The wireless weather stations METEOTIME DUO, NEXUS and SINUS have their own internal sensors to measure the climate at the installation site and remote transmitters for elsewhere, indoor or outdoor. The time is received via the DCF-77 radio signal.

The built-in memory in the SINUS and NEXUS weather stations allows you to record 200 weather data and the METEOTIME DUO stores up to 3000 weather data.

Simply connect the station to your computer via the built-in USB interface and use the free software to evaluate all weather data from the METEOTIME DUO, NEXUS or SINUS wireless weather station.

The NEXUS and SINUS weather stations measure the temperature, humidity, wind speed, rainfall and air pressure.
The METEOTIME DUO weather station measures the temperature, humidity, wind speed and rainfall.

Quick help with answers to frequently asked questions

Yes, the PC software for the NEXUS, SINUS and METEOTIME DUO weather stations is compatible with the Windows 10 operating system.

As of Windows 8.1, Microsoft has changed internal protocols for USB ports (stricter energy management), which sometimes makes it impossible to automatically connect the station (NEXUS / SINUS / METEOTIME DUO) to the PC via software.

For manual connection to the station, please follow these 6 steps:

  1. First remove the USB cable from the PC
  2. Launch the software
  3. Close the info window “USB cable not connected!“
  4. Now re-insert the USB cable and connect the station to the PC with the USB cable
  5. Then initiate a manual connection via “File” => “Import new data”
  6. After a few seconds, the connection should be activated
  • To quickly update a transmitter, first make sure that it’s fitted with the correct 1.5V batteries.
  • Then place the transmitter right next to the station to completely rule out impairment caused by radio interference.
  • Now hold down the “down arrow” button for 3 seconds to activate the manual station search. Note: The down arrow is found on the front of the SINUS and NEXUS weather stations; on the METEOTIME DUO, the down arrow is found on the back of the unit.
  • Please check whether the transmitter can be received again on the base station.

As a further test place the faulty transmitter next to a second transmitter, which is easily received.
Now start the manual search.

The transmitter is received again.
If this is the case, the radio signal may be affected by the distance between the base unit location and the original location of the transmitter.
Change the location of the base station and / or the transmitter until a reception is possible.

The transmitter is still not showing on the base station.
Please contact our customer service.

You can delete the data storage completely by resetting the base unit to factory setting.

For a factory reset, take the following steps:

  1. First press and hold the “SNOOZE” or “LIGHT” button and simultaneously press the up arrow button for 4 seconds.
  2. When the backlight starts flashing, the two buttons can be released. Now just press the “SET” button
  3. The NEXUS and METEOTIME DUO now beeps for about 2 minutes; the SINUS only for a few seconds. Finally, switch off the base station.
  4. Wait a few minutes and then put the station back into operation.

This is usually due to the display settings in Windows.

For the correct display of the software, the DPI scaling for icons and font size should always be set to “Normal – 96 DPI”. (You find this under windows display setting.)

The accumulated rainfall can be reset as follows:

  1. Restart the rain transmitter: remove the batteries and replace them after 1 minute.
  2. Activate the manual station search on the base station immediately after restarting the transmitter.
  3. Once a new record is saved, the total amount of rain is reset to zero and begins counting again. The display of the amount of rainfall for the intervals in the station, e.g. Last Hour, Last 24H, Yesterday, etc. is not affected.
  • To set the reference value, select “SEA LEVEL” in the “WEATHER / PRESSURE” display by simply pressing the “SET” button.
  • Then hold down the “SET” button for 3 seconds until the value flashes.
  • Now you can use the arrow keys to set the current reference value.

The relative air pressure at your location can be found on the Internet, with public bodies or at your local weather service.

No, the currently prevailing relative air pressure must be set again after restarting.

No, because you can adjust your current relative air pressure directly.
The sea level is only relevant if you cannot find a reference value. Basically, we recommend that you use the relative air pressure as the reference value, as this makes the measurement more accurate.

Current rainfall levels are not included in the Yesterday, Last Week and Last Month periods, as they provide information about the last completed period.

The current amount of rainfall is displayed in both time ranges “Last Hour” and “Last 24 Hr”.

To start a new history file, delete the current history file from the “Data” folder in the installation directory of the software.

  • Weather station NEXUS and METEOTIME DUO: “Nexusorg.dbf”
  • Weather station SINUS: “Sinusorg.dbf”.

Alternatively, you can also copy and rename the file to get the original values.
A new history file is automatically created the next time you start the software.

We recommend that you attach your wind transmitter to a pole and align the sensor support arm to the north. This way, your wind sensor is pointing north and already works with the factory settings.

A compass will help you to see where North is at your location.

If you already have aligned the wind sensor to the north during installation, no manual adjustment of the wind direction is necessary. Not even after a restart.

If it is not possible to align the support arm to the north, after fixing the wind transmitter, the wind vane must be aligned to the north and the “SET” key pressed.
The SET “button can be found in the battery compartment and can be easily operated with a pointed object. Please also follow these steps after each restart of the wind transmitter to set the wind direction correctly.

The values differ for the following reasons:

  • The online data differs from the wind data that you measure locally at your location because the wind force is affected by buildings and other local conditions. Public weather stations are usually set up in especially ideal locations
  • The wind speed displayed on NEXUS, SINUS or METEOTIME DUO is an average of the past 10 minutes.
  • Depending on the set storage interval, only the actual value at the time of storage is recorded. Measuring that occur between two storage periods are displayed live only on the device; any maximum or minimum values in the max-min memory are recorded.
  • The display for the wind data is set in gusts on the NEXUS, SINUS or METEOTIME DUO weather stations. This display is completely updated with each transmission interval and therefore can also indicate higher wind speeds (gusts).

No, this is not possible. The time of storage is determined by the base unit and it depends on the time of initialization.
