Frequently Asked Questions - WS5400 ALECTO

How to connect the WS5400 weather station to Wi-Fi?

Press the Sensor / Wi-Fi button for 6 seconds to enter AP mode (the AP symbol and Wi-Fi icon flash). Open the Smart Life app on your smartphone, follow the instructions to add a device. Make sure you are connected to a 2.4 GHz network (not 5 GHz). Once connected, the console automatically exits AP mode.

How to set the time manually?

Hold the CH / SET button for 2 seconds to enter setting mode. Briefly press CH / SET to go to the next step. Use WIND / + or NDX / - to change values. To set the time manually, first disable auto synchronization (step 8) by setting to OFF. Then set the time and date.

What to do if the console no longer displays outdoor data (shows 'Er')?

This means the signal has been lost for over 48 hours. Replace the outdoor unit batteries with new ones (preferably lithium). Press the Sensor / Wi-Fi button to force a resynchronization. If the problem persists, check the distance and obstacles between the two units.

How to reset the console to factory settings?

For a full reset, hold the RESET button (on the back of the console) for 6 seconds. This will erase all data and settings. You can also remove the CR2032 backup battery and unplug the power adapter.

How to interpret the Beaufort scale on the station?

The Beaufort scale classifies wind force from 0 (calm) to 12 (hurricane). Press the WIND / + button to toggle between average speed, gusts, direction, and the Beaufort scale (BFT). For example, BFT 3 corresponds to a 'gentle breeze' (12-19 km/h).

How to calibrate the temperature or humidity sensors?

Hold the CAL button for 2 seconds to enter calibration mode. Use CH / SET to select the parameter to calibrate (indoor temperature, outdoor humidity, etc.). The value flashes: adjust the offset with WIND / + or NDX / -. Press CAL to exit.

How to clean the UV sensor?

Gently clean the UV sensor lens with a damp microfiber cloth. Avoid abrasive products. Regular cleaning ensures accurate UV measurements. The sensor may degrade over time; calibration with a professional UV meter is possible via calibration mode.

What is the maximum range between the console and the outdoor sensor?

The range is about 100 meters in direct line of sight with no obstacles. For better reception, avoid thick walls, electronic devices (microwaves, TVs) and install the sensor at least 1.5 m above ground.

How to use the alarm and snooze function?

Hold the ALARM button for 2 seconds to set the alarm time. Use WIND / + or NDX / - to change hours and minutes. Briefly press ALARM to enable/disable the alarm. When it sounds, press SNOOZE / CONTRASTE for a 5-minute snooze, or hold it to stop until the next day.

How to interpret the displayed weather forecasts?

The station uses the barometer to predict weather within 12 to 24 hours within a radius of 30 to 50 km. The icons are: sunny, partly cloudy, cloudy, rainy/stormy, snowy (if outdoor temperature < -3°C). Accuracy is about 70 to 75%. The forecast reflects a trend, not the current weather.

WEATHER FORECAST

The built-in barometer continually monitors atmospheric pressure. Based on the data collected, it can predict the weather conditions in the forthcoming 12\~24 hours within a 30\~50km (19\~31 miles) radius.

The accuracy of a general pressure-based weather forecast is about 70% to 75%.

The weather forecast is reflecting the weather situation for next 12\~24 hours, it may not necessarily reflect the current situation.

The SNOWY weather forecast is not based on the atmospheric pressure, but based on the temperature of outdoor. When the temperature is below -3^ (26°F), the SNOWY weather icon will be displayed on the LCD.

BAROMETRIC PRESSURE

The atmospheric pressure is the pressure at any location of the earth caused by the weight of the column of air above it. One atmospheric pressure refers to the average pressure and gradually decreases as altitude increases. Meteorologists use barometers to measure atmospheric pressure. Since variation in atmospheric pressure greatly affected by weather, it is possible to forecast the weather by measuring the changes in pressure.
