My Storm unit always reports the wind direction as North, I have checked the unit and the wind vane is rotating freely?
Thanks for reaching out. I would first charge the Storm via an USB cable for several hours.
You may then try to reset both Storm (anemometer) and Storm dongle. There is a small hole next to the USB socket under the rubber cover on Storm and on the dongle next to the power socket. Use a paper clip, insert it into the hole and press and hold a small button there for about 10 seconds. Do it for both the anemometer unit and the dongle (leave dongle powered during the reset). You may need to delete Storm and add it again in the BloomSky app after the reset.
Both Storm and dongle contains a standard RF transceiver model:
Texas Instruments CC1110F32, Ti 651, CN2K G4
Frequency Bands: 315/433/868/915 MHz ISM/SRD
Frequency range: 300 – 348 MHz, 391 – 464 MHz, 782 – 928 MHz
This transceiver has an interconnecting frequency auto negotiation function. It may be possible that the frequency negotiation was not successful on your unit.
When anemometer and dongle communicate successfully the indicator light on the dongle’s top is blinking in a repetitive pattern 15-17 times green and then once red. While red means data transfer from the anemometer to the dongle.
Please do let me know how it goes.
