Frequently Asked Questions

Simply moving your display console (or receiver) to a different location may easily fix the communication issue.

We recommend the following best practices for trouble free wireless communication.

1. Fresh Batteries. If applicable, make sure there are fresh batteries in both the console and remote. Remember to power up the console last when changing batteries. Do not use rechargeable batteries. They have a lower voltage and lower range than non-rechargeable batteries.
2. Electro-Magnetic Interference (EMI). Keep the console several feet away from computers, TVs and electronic cables.
3. Radio Frequency Interference (RFI). If you have other 433/915 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.
4. Cold Weather. If the temperature is below < 10 degF, use e2 energizer batteries (Lithium), available in most stores batteries are sold (blue in color). Alkaline and NMH (nickel metal hydride) batteries do not operate below 10 degF.
5. Sensor orientation.  To insure proper communication, mount the remote sensor on a vertical surface, such as a wall.  Do not lay the sensor flat if this is a small remote sensor.
6. 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.
7. 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.
8. Defective Sensor. It is possible the remote sensor is defective. If you have not done so already, to replace under one year warranty, please visit AmbientWeather.com/rma.html

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.

Temperature can read too low (or inaccurate) at night when placed close to a radiant heat source, like a house, building or structure.  It can also read lower then other stations in your area due to irrigation or sprinklers.

1. Place the sensor inside next to the indoor console sensor. Wait about 1 hour for stabilization. The sensors should agree within the accuracy specifications. Most RTD (resistive thermal device) sensors are accurate within +/- 2 degF. Thus, the sensors should agree within 4 degF.
2. Mercury or red spirit thermometers are very accurate. Inside your house, place a red spirit thermometer next to the digital thermometer. The thermometers should agree within 2 degF.
3. For colder temperature verification, place the sensor with the red spirit thermometer in the regrigerator or freezer.
4. If the sensor is separate, place the sensor in a shaded area on the north side of the structure to avoid direct and radiant heat.
5. Temperature sensors that do not have radiation shields will absorb solar energy and read higher than the ambient temperature. To prevent this problem, purchase a solar radiation shield from Ambient Weather.
6. We have a one year warranty and a 30 day return policy. For details, please visit: www.AmbientWeather.com/rma.html

1. Place the sensor inside next to the indoor console sensor. Wait about 24 hours for stabilization. The sensors should agree within the accuracy specifications. Most digital capacitive hygrometer sensors are accurate within +/- 5%. Thus, the sensors should agree within 10% when considering full tolerance stack up.Note that humidity accuracy, like most other measurement parameters, are a percentage of full scale, and not a percentage of point.
2. Sling psychrometers are very accurate. Perform a formal calibration. The humidity should agree within 5% of the  rating. You can also make your own calibration kit. For details, visit:

Testing The Accuracy Of A Hygrometer - Saturated Salt Test?

3.   Place the sensor in a shaded area on the north side of the structure to avoid direct and radiant heat.

4.  Humidity is significantly impacted by external factors like location and water (grass, lakes, rivers, etc). Insure proper installation. You cannot use a source like the National Weather Service. There are several reasons:

• The NWS may update once per hour.
• The NWS has strict installation guidelines (no unnatural structures, bodies of water, or unnatural vegetation nearby).

5.  If the problem persists, we have a one year warranty. Visit: www.AmbientWeather.com/rma.html

None of the Ambient Weather Stations support repeaters or boosters at this point in time.

To set the dip switches in an 8 channel sensor, there are three dip switches with 8 different combinations.

After you set the dip switches, you must always power down and up the remote sensor by removing and reinserting the batteries for the change to take effect.

Why do we do it this way instead of an 8 position switch? The reason is 8 position switches are much more difficult to implement, less reliable and takes up more space.

If the temperature or humidity does not match between what is displayed on the remote sensor and what is displayed on the console:

1. If you own more than one remote sensor:
   The sensor has a channel number displayed on it, next to the temperature. Make sure that that Channel Number displayed on sensor matches the channel number shown on the display. If they do not match, refer to your User Manual on how to switch the channel display.
2. It is possible the temperature or humidity were adjusted or calibrated unintentionally. Refer to your individual User Manual on how to remove or correct the adjustment from the console.

   Here is an example:

• Remote sensor reads 70.0
• Console for the same sensor channel reads 71.2
• Adjust the console down 1.2 degrees to match 70.0.

If the sensor(s) have stopped communicating to your console,  it may be as simple as placing the remote(s) (powered up) about 10 feet away from the console, power down and up the console by removing one or more batteries, disconnecting from AC power (if applicable), wait 30 seconds, and put the batteries back in, then wait several minutes to resync.

DO NOT TOUCH ANY BUTTONS and look for the search icon. Wait until the search icon turns off before pressing any buttons.

If you have more than one sensor, make sure they are programmed to transmit on different channels.

If the problem persists, we have a one year warranty. To replace under warranty, please visit: www.AmbientWeather.com/rma.html

1. Replace the batteries. We recommend the following batteries:
   My Rechargeable Batteries No Longer Work. Which Batteries Are Recommended For My Weather Station?

The low voltage icon or indicator will be present on the console next to the sensor reading if the voltage falls below 2.4 Volts.

If you own more than one sensor, make sure the first sensor is on Channel 1 and the second sensor is on Channel 2.

To set the dip switches, please reference:

How Do I Set The Channel Number Using The Dip Switches In The Sensor?

Next, place all remote sensors about 10′ from the console, and then power down and up the display console. Do not touch any buttons for several minutes, until the search icon  on the display turns off.

If the problem persists, change the channel 2 sensor to channel 1 and visa versa (switch both sensor channels) and repeat the process above. Does the problem follow the sensor, or does it remain on channel 2?

If the sensor problem remains on Channel 2, the console will need to be replaced.

If the sensor problem moves to Channel 1, the sensor will need to be replaced.

Floating Pool & Spa Thermometer loses reception

1. Sensor placement is important, since the wireless signal cannot pass through Earth or ground.  Tethering the sensor to the side of the pool that is line of sight to the sensor is recommended:
   
2. Keep the console away from any electronic radiating sources, like phones, TVs and computers.
3. If the sensor(s) have stopped communicating to your console,  it may be as simple as placing the remote(s) (powered up) about 10 feet away from the console, power down and up the console by removing one or more batteries, disconnecting from AC power (if applicable), wait 30 seconds, and put the batteries back in, then wait several minutes to resync. DO NOT TOUCH ANY BUTTONS and look for the search icon. Wait until the search icon turns off before pressing any buttons.If you have more than one sensor, make sure they are programmed to transmit on different channels.
