Setting Started

Install U-bolts and mounting pole

Installation of the U-bolts, which are in turn used to mount the sensor package on a pole, requires installation of an included metal plate to receive the U-bolt ends. The metal plate, visible in Figure 3 has four holes through which the ends of the two U-Bolts will fit. The plate itself is inserted in a groove on the bottom of the unit (opposite side of solar panel). Note that one side of the plate has a straight edge (which goes into the groove), the other side is bent at a 90-degree angle and has a curved profile (which will end up “hugging” the mounting pole). Once the metal plate is inserted, insert both U-bolts through the respective holes of the metal plate as shown in Figure 3.

Loosely screw on the nuts on the ends of the U-bolts. You will tighten these later during final mounting. Final assembly is shown in Figure 4.

The plate and U-Bolts are not yet needed at this stage but doing this now may help avoid damaging the wind vane and the wind speed cups later on. Handling of the sensor package with wind vane and speed cups installed to install these bolts is more difficult and more likely to lead to damage.

Install wind speed cups

Push the wind speed cup assembly onto the shaft on the top side of the sensor package, as shown in Figure 5 (left side image). Tighten the set screw, with a Philips screwdriver (size PH0) (right side image). Make sure the cup assembly can rotate freely. There should be no noticeable friction when it is turning.

Install wind vane

Push the wind vane onto the shaft on the opposite side to the wind cups, until it goes no further, as shown in Figure 6 (left side image). Next, tighten the set screw, with a Philips screwdriver (size PH0) (right side image) until the wind vane cannot be removed from the axle. Make sure the wind vane can rotate freely. The wind vane’s movement has a small amount of friction, which is helpful in providing steady wind direction measurements.

Install Batteries

Open the battery compartment with a screwdriver and insert 2 AA batteries in the battery compartment. The LED indicator on the back of the sensor package will turn on for four seconds and then flash once every 48 seconds indicating sensor data transmission (the sensor transmission update period).

Note: If LED does not light up or is on permanently, make sure the battery is inserted the correct way and inserted fully, starting over if necessary. Do not install the batteries backwards as it may permanently damage the outdoor sensor.
Note: We recommend Lithium batteries for cold weather climates, but alkaline batteries are sufficient for most climates. Rechargeable batteries have lower voltages and should never be used.

Mount outdoor sensor

Before proceeding with the outdoor mounting detailed in this section, you need to make sure the base station can receive the data from outdoor sensor, while you keep the assembled outdoor sensor package nearby (although preferably not closer than 1.5m from the console). This will make any troubleshooting and adjustments easier and avoids any distance or interference related issues from the setup. After setup is complete and everything is working, return here for outdoor mounting. If issues show up after outdoor mounting they are almost certainly related to distance, obstacles etc.

Mounting

Reference Figure 8, the mounting assembly includes two U-Bolts and a bracket that tightens around a 1 to 2” diameter pole (not included) using the four U-Bolt nuts.
Note Beside the antenna, there is an arrow icon with “WEST” words (Figure 9) representing the direction of west. The sensor body has to be adjusted so that the “WEST” indication is facing to real west direction in your location. A compass device is recommended to help adjust direction. Permanent wind direction error will be introduced when the outdoor sensor is not installed in right direction.  direction error will be introduced when the outdoor sensor is not installed in right direction. direction error will be introduced when the outdoor sensor is not installed in right direction.

Reset Button and Transmitter LED

Using a bent-open paperclip, press and hold the RESET BUTTON (see Figure 10) to affect a reset: the LED turns on while the RESET button is depressed, and you can now let go. The LED should then resume as normal, flashing approximately once every 48 seconds.

Best Practices for Wireless Communication

To ensure proper communication, mount the remote sensor(s) upright on a vertical surface, such as a wall. Do not lay the sensor flat. Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the following best practices for trouble free wireless communication.

• Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and TVs.
• Radio Frequency Interference (RFI). If you have other 433/868/915 MHz devices and communication is intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or receivers to avoid intermittent communication.
• Line of Sight Rating. This device is rated at 300 feet line of sight (no interference, barriers or walls) but typically you will get 100 feet maximum under most real-world installations, which include passing through barriers or walls.
• Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If you have metal siding, align the remote and console through a window to get a clear line of sight. The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction decreases the transmission range by the factor shown below.
  Medium| RF Signal Strength Reduction
  ---|---
  Glass (untreated)| 5-15%
  Plastics| 10-15%
  Wood| 10-40%
  Brick| 10-40%
  Concrete| 40-80%
  Metal| 90-100%

Maintenance

1.  Clean the rain gauge once every 3 months. Rotate the funnel counter-clockwise and lift to expose the rain gauge mechanism, and clean with a damp cloth. Remove any dirt, debris and insects. If bug infestation is an issue, spray the array lightly with insecticide.
2.  Clean the solar panel every 3 months with damp cloth.
3.  Replace batteries every 1-2 years. If left in too long, the batteries may leak due to environmental challenges. In harsh environments, inspect the batteries every 3 months (when cleaning the solar panel).
4.  When replacing the batteries, apply a corrosion preventive compound on the battery terminals, available at most hardware stores.
5.  In snowy environments, spray the top of the weather station with anti-icing silicon spray to prevent snow build up.
