3. Warnings and Cautions
- ⚠️ Warning: Any metal object may attract a lightning strike, including your weather station mounting pole. Never install the weather station during a storm.
- ⚠️ Warning: Installing your weather station in a high location may result in injury or death. Perform as much of the initial check out and operation on the ground and inside a building or home. Only install the weather station on a clear, dry day.
4. Pre-Installation Checkout and Site Survey
4.1 Pre Installation Checkout
Before permanent installation, it is recommended to operate the weather station in a temporary, accessible location for one week. This allows you to verify all functions, ensure proper operation, familiarize yourself with calibration procedures, and test the wireless range.
4.2 Site Survey
Perform a site survey before installing the weather station. Consider the following:
- Ensure easy access for cleaning the rain gauge (every few months) and changing batteries (every 1-2 years).
- Avoid radiant heat transfer from buildings and structures. Install the sensor array at least 5 feet away from any building, structure, ground, or roof top.
- Avoid wind and rain obstructions. Install the sensor array at least four times the height of the tallest obstruction away. For example, if a building is 20 feet tall and the mounting pole is 6 feet tall, install the array 56 feet away (4 x (20 - 6) = 56). Use common sense; installing near a tall building may affect wind and rain accuracy.
- Wireless Range: In an open field, communication can reach up to 300 feet. Obstacles like buildings, trees, and high voltage lines reduce this range. Wireless signals will not penetrate metal buildings. Under typical conditions, the maximum range is about 100 feet.
- Radio Interference: Devices like PCs, radios, or TV sets can interfere with or cut off radio communication. Position the display console at least five feet away from any electronic device to avoid interference.

The thermo-hygrometer-transmitter (THT) is pre-packaged inside the rain shield. Pull the transmitter from the shield to expose the LED indicator, sensor sockets, and battery compartment, as shown in Figure 3.
Figure 3: Thermo-Hygrometer Transmitter Diagram shows the THT unit with labels for LED Indicator, Wind Sensor Socket, Rain Sensor Socket, Battery Compartment, Mounting Bracket, and Battery Cover.
Remove the battery cover and insert 2 x AA batteries into the compartment, observing polarity, as shown in Figure 4. The red LED above the battery compartment should light up for four seconds, then turn off. The LED will flash every 48 seconds thereafter, indicating wireless transmission. Close the battery door.
Figure 4: Battery Insertion illustrates the correct placement of AA batteries into the transmitter's battery compartment, showing polarity markings.
6.2 Connect and Mount the Sensor Array (Pole Mount)
Reference Figure 5 for assembly steps:
- Attach the wind cups to the wind speed shaft; they snap into place.
- Connect the wind cup shaft to the rain shield.
- Secure the wind cup shaft to the rain shield with the 30mm bolt and nut.
- Connect the wind sensor connector to the WIND sensor socket.
- Connect the rain sensor connector to the RAIN sensor socket.
- Insert the transmitter into the rain shield until snug.
- Attach the transmitter to its mounting bracket.
- Secure the transmitter to the mounting bracket with the 19.5mm bolt and nut.
- Attach the rain gauge to its mounting bracket and secure with the 10mm set screw.
- Attach the rain gauge mounting bracket to the mounting pole (not included) using two U-bolts and nuts. Use the 8mm wrench to tighten. Ensure the rain gauge is level using its bubble level.
- Attach the thermo-hygrometer transmitter and wind gauge mounting bracket to the mounting pole (not included) using two U-bolts and nuts. Tighten with the 8mm wrench.
? Note: Mount the rain gauge below the wind transmitter and wind gauge to prevent water discharge from affecting connectors.
Figure 5: Sensor Array Pole Mount Diagram visually guides the assembly and attachment of the wind speed sensor, thermo-hygrometer, and rain gauge to a mounting pole, with numbered steps corresponding to the instructions.
6.3 Alternate Mounting to a Horizontal Surface
The wind gauge and rain gauge can alternatively be mounted to a horizontal surface using the 4 x 15mm set screws, as shown in Figure 6.
Figure 6: Horizontal Mounting Diagram shows how the rain gauge and wind gauge can be attached to a flat surface.
6.4 Display Console
6.4.1 Display Console Layout
The display console layout is shown in Figure 7. Note that alarm icons appear only when an alarm is set. The low battery icon (?) appears when batteries are low. The SENSOR icon (?) is visible during initial search mode and flashes every 48 seconds thereafter.
Figure 7: Display Console Layout Diagram provides a detailed view of the console screen, with numbered labels pointing to specific display elements such as Time, Indoor/Outdoor Temperature and Humidity, Barometric Pressure, Wind Speed, Rain data, Forecast Icons, and various status indicators.
Figure 8: Back of Display Console shows the layout of the battery compartment, desk stand, and wall hanging hole on the rear of the console.
6.4.2 Initial Display Console Set Up
- Place the sensor array 5 to 10 feet from the display console for initial setup.
- Ensure the sensor array is powered on and its transmitter light flashes every 48 seconds.
- Insert 3 x AA batteries into the console's battery compartment. All LCD segments will light up briefly to confirm functionality.
- The console will then display indoor temperature, humidity, barometer, tendency, date, and time. Outdoor data (wind, rain, outdoor temp/humidity) will update within minutes. DO NOT TOUCH ANY BUTTONS until outdoor data appears, or the sensor search mode will terminate. The sensor search icon (?) will be present.
- Once outdoor transmitter data is received, the console will attempt to receive the Radio Controlled Clock (RCC) signal.
If outdoor sensors do not update, refer to the troubleshooting guide in Section 12.
6.4.3 Radio Controlled Clock (RCC)
After receiving sensor array data, the sensor transmits weather data for 30 seconds, then begins RCC reception. During RCC reception (up to 10 minutes), no weather data is transmitted to avoid interference, and the sensor search icon (?) remains on.
If signal reception fails within 1 minute, the search cancels and resumes every two hours. The regular sensor link resumes after RCC reception. In some locations, RCC reception may take days.
The RCC routine can be cancelled by pressing any button. The sensor search icon will turn off, and the console will return to normal mode.
Once RCC is received and the clock is set, the RCC icon (?) will appear in the date and time field.
? Note: The RCC signal originates near Fort Collins, Colorado. It travels by bouncing off the ionosphere. Signal is better at night due to solar interference. Urban environments can also affect the signal.
6.4.4 Sensor Operation Verification
Verify sensor operation before outdoor installation:
- Rain Gauge: Tip the sensor array. You should hear a clicking sound. Verify the rain reading is not 0.00 (each click = 0.01 inches).
- Wind Speed: Rotate wind cups manually or with a fan. Verify wind speed is not 0.0.
- Temperature: Place console and sensor array about 10 feet apart. Indoor and outdoor temperatures should match closely (within 4°F / 2°C accuracy). Allow 30 minutes for stabilization.
- Humidity: Place console and sensor array about 10 feet apart. Indoor and outdoor humidity should match closely (within 8% accuracy, ± 4%). Allow 30 minutes for stabilization.
7. Weather Station Installation
7.1 Pre Installation Checkout
Before permanent installation, operate the weather station in a temporary location for one week to check functions, ensure proper operation, and test wireless range.
7.2 Site Survey
Perform a site survey before installation. Consider:
- Easy access for annual rain gauge cleaning and battery changes (every 1-2 years).
- Avoid radiant heat from buildings. Install sensor array at least 5 feet from structures.
- Avoid wind and rain obstructions. Install sensor array at least four times the height of the tallest obstruction away. If a building is 20 ft tall, install 80 ft away (4 x 20 ft). Wind and rain readings may be inaccurate if installed too close to tall structures.
- Wireless Range: Up to 300 feet line-of-sight in open fields. Obstacles reduce range significantly. Signals do not penetrate metal buildings. Typical range is ~100 feet.
- Radio Interference: PCs, radios, and TVs can disrupt communication. Position the console away from such devices.
- Visit Ambient Weather Mounting Solutions for mounting ideas.
7.3 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls, and metal barriers. Follow these practices:
- Electro-Magnetic Interference (EMI): Keep the console several feet from monitors and TVs.
- Radio Frequency Interference (RFI): If communication is intermittent, try turning off other 433 MHz devices. Relocate transmitters or receivers if necessary.
- Line of Sight: Rated for 300 feet line-of-sight. Expect ~100 feet in real-world conditions with barriers.
- Metal Barriers: RF signals do not pass through metal (e.g., aluminum siding). Align remote and console through a window for a clear line of sight if metal siding is present.
The following table shows reception loss based on transmission medium:
| Medium | RF Signal Strength Reduction |
|---|---|
| Glass (untreated) | 5-15% |
| Plastics | 10-15% |
| Wood | 10-40% |
| Brick | 10-40% |
| Concrete | 40-80% |
| Metal | 90-100% |
7.4 Final Installation of Sensor Array

8.6 Other Console Features
8.6.1 Weather Forecasting
? Note: Forecasts are based on barometric pressure changes. Increasing pressure generally indicates improving weather (sunny/partly cloudy); decreasing pressure suggests deteriorating weather (cloudy/rain).
The forecast is an estimation for the next 24-48 hours and varies by location. It is a tool for projecting conditions, not an accurate prediction.
8.6.2 Weather Icons
The console displays four weather icons: Sunny, Partly Cloudy, Cloudy, and Rainy. Two tendency indicators show air pressure trends.
Weather Icons: ☀️ (Sunny), ☁️ (Partly Cloudy), ☁️ (Cloudy), ?️ (Rainy).
8.6.3 Weather tendency indicator
A tendency arrow indicates air pressure trend: ➡️ (increasing pressure, improving weather) and ⬅️ (decreasing pressure, deteriorating weather).
The indicator flashes for three hours if conditions are changing, then becomes fixed when stable.
Example 1: Pressure is decreasing, weather is deteriorating.
Example 2: Pressure is increasing, weather is improving.
8.6.4 Storm threshold indicator
The storm threshold (negative pressure change rate) is adjustable from level 3 to 9 (default 4). If a negative rate is exceeded for 3 hours, a storm warning indicator activates, showing rain clouds and tendency arrows for 3 hours.
8.6.5 Pressure threshold setting
The pressure threshold (rate of pressure change signifying weather change) is adjustable from level 2 to 4 (default 2). Lower levels increase sensitivity to weather changes.
8.6.6 Pressure Graph
? Note: The bar graph displays the last 24 hours of barometric pressure, flashing right to left. Each bar represents three hours.

| Problem | Solution |
|---|---|
| Wireless remote (thermo-hygrometer) not reporting to console. There are dashes on the display console. | Maximum line-of-sight range is 300'. Move sensor assembly closer to console. If too close (less than 10'), move away. Power cycle console by removing/re-inserting batteries. Verify remote sensor LED flashes every 45 seconds. Install fresh batteries (lithium for cold weather). Ensure sensors are not transmitting through solid metal or earth barriers. Move console away from electrical noise sources (PCs, TVs). Move remote sensor to a higher location. RF sensors struggle with metal barriers or multiple thick walls. Allow up to 1 hour for sensors to stabilize. Indoor/outdoor temperature should agree within 4°F; humidity within 10%. |
| Absolute pressure does not agree with official reporting station | You may be viewing relative pressure. Select absolute pressure. Calibrate sensor to an official local weather station. Barometer accuracy is ± 0.08 inHg within 27.13-32.50 inHg (altitude -2,200 to 2,700 ft). Higher altitudes may have non-linearity. |
| Rain gauge reports rain when it is not raining | Unstable mounting may cause false rain increments. Ensure stable mounting. Consider flat, stable surface mount instead of pole mount. |
| Barometer graph flashes. Can I turn this off? | No, this feature cannot be turned off. |
| Wind speed appears low | Switch display to wind gust. |
| Can the lamp be turned on all of time? | No, it turns on temporarily to prevent bulb burnout. |
| The forecast icon is not accurate | The console needs several days to trend barometric pressure. Forecasts are estimations and vary by location; they are not precise predictions. |
