Levenhuk Wezzer PRO LP300 Weather Station

The kit includes: display console, outdoor sensor (thermohygrometer, rain gauge, wind speed sensor, wind
vane), U-bolt with mounting clamps (2 pcs.), USB cable, user manual, and warranty card.

ATTENTION! Please remember that mains voltage in most European countries is 220−240V. If you
want to use your device in a country with a different mains voltage standard, remember that use
of a converter is absolutely necessary.

Getting started

Pre-installation checkout
Before permanent installation, it is recommended to use the weather station for a week in easily accessible
temporary location. This will allow you to test its performance, to become familiar with its functions and
controls, and to determine its wireless range.

Site survey

Perform a survey of the site before weather station installation. Consider the following:
Maintenance access. Regularly clean the rain gauge and swap batteries every 2−3 years. Ensure easy access to
the weather station.

Radiant heat from buildings and structures. Install the multisensor at least 1.5m from any buildings,
structures, ground, or rooftops.
Rain and wind obstructions. For precise measurements of wind and rain, install the multisensor at a height
at least 4 times that of the nearest obstacle. For example, if the building is 6m tall, and the mounting pole
is 2m tall, the sensors should be installed at a height of at least 16m (4 х (6 − 2)).
Wireless range. The optimal distance between the receiver and the transmitter is up to 100m in an open
space. With obstacles in the way (buildings, trees, etc.), the maximum distance is 30m.
Radio interference from computers, radios, or TVs. Install the display console at least 1.5m away from
electronic devices to minimize interference.

Sensor setup

Installing U-bolts and the mounting pole
Install the included metal plates to secure the U-bolts (8) to the mounting post (not included). The metal plate
is inserted into the groove on the bottom of the device (opposite side from the solar panel (6)). One side of the
plate has a straight edge (inserted into the groove), the other side is bent at a 90-degree angle and has
a curved profile that wraps around the mounting pole.
After inserting the metal plate, remove the nuts from the U-bolts and insert both bolts into the corresponding
holes in the plate.
Screw the nuts onto the ends of the U-bolts. Make sure to tighten them completely during final mounting.

Wind vane installation

Slide the wind vane (2) onto the sensor shaft. Tighten the fastening screw with a PH0 screwdriver to make sure
the vane is tight in place.

Wind speed sensor installation
Place the wind speed sensor (1) onto the shaft. Tighten the fastening screw. Make sure the wind speed sensor
spins freely.

Rain gauge installation
Install the rain gauge funnel (4) and rotate it clockwise to attach to the remote sensor.

Batteries installation
Insert 2 AA batteries into the battery compartment (9). The LED indicator (11) on the back of the transmitter
blinks every 48 seconds (sensor data transmission refresh period).

ATTENTION! If the LED does not light up or stays on, make sure the batteries are inserted properly
and the device is reset correctly. Incorrect installation of batteries may cause permanent damage
to the outdoor sensor.

ATTENTION! Alkaline batteries are suitable for most climates, but 1.5V lithium batteries are
recommended in cold climates. Rechargeable batteries are not recommended due to their low
voltage, instability over a wide temperature range, and short service life, which results in poor
signal reception.

Mounting the assembled multisensor
Attach the multisensor to the prepared 2.5−5.0cm diameter pipe using U-bolts and a bracket.
Align the multisensor in the West direction by rotating it on the mounting pipe. The WEST arrow, located at
the top of the multisensor next to the antenna (7), should point due west. Use a compass for fine adjustments.
Once oriented correctly, tighten the bolts.

ATTENTION! Check with the bubble level (5), to ensure the multisensor is set up horizontally. The
bubble must be completely inside the red circle, otherwise the wind direction and speed, as well
as the amount of precipitation may be measured inaccurately. If the bubble is close to the center
of the circle, but not completely inside it, and you cannot adjust the mounting pipe, you can place
small wood or heavy cardboard wedges between the sensor and the top of the mounting pole to
achieve the desired result (this will require loosening the bolts and some experimentation).

Reset button and transmitter LED
If the multisensor is not transmitting data, perform a reset. Press and hold RESET for 3 seconds until the
LED (11) lights up. Once the LED lights up, release the button. The LED should resume its normal operation,
flashing every 48 seconds.

Recommendations for improving wireless connectivity

To avoid radio frequency interference, we recommend that you adhere to the following conditions.

Place the console several meters away from computer monitors and TVs.
If you have devices on the 433MHz frequency and are experiencing intermittent connectivity, please unplug
them to troubleshoot.
The maximum range of the device is 100m without, and 30m with obstacles.
The radio signal does not pass through metal. With metal siding, place the sensor and console so that there
is a window between them.

PC connection

A weather station is a self-sufficient device capable of collecting and displaying weather data. However, for
deeper analysis and data storage, it can be connected to a PC via a USB cable. In offline mode, the weather
station stores up to 4080 complete sets of weather data with time and date in its internal memory. If the
memory is full, the old data gets written over with new one. Some data and settings, including data storage
intervals from 5 to 240 minutes, are only accessible via PC.
To work with the weather station on a PC, you need to install the EasyWeather software, which can be
downloaded from the official Levenhuk website. This software displays the current and historical weather data
and enables you to save and upload it to weather servers.
