Weather

The Weather app decodes wireless temperature and humidity transmissions from consumer weather stations operating in the ISM licence-free bands. It receives AM-mode OOK signals and presents a live list of decoded sensor readings, updated in real time.

Settings

• Frequency: Default 433.920 MHz. Adjustable in 10 kHz steps using the encoder knob, or tap to open the keypad. Common frequencies are listed below.
• Temperature unit: °C or °F. Applies to both the list view and detail view.
• RF Amp (0 or 1): Enables/disables the internal RF amplifier. Use with caution on strong nearby signals.
• LNA gain (0–40): Low-noise amplifier gain. See Receive Quality Issues.
• VGA gain (0–62): Variable-gain amplifier gain.
• Volume: Volume for packet beep tones. Only active when Beep on packets is enabled in the global Settings.
• Clear: Clears the in-memory sensor list. Does not affect any log file.
• Log: Checkbox to enable CSV logging. When checked, a new log file is created immediately. The log state is saved to rx_weather.ini and restored on next launch — if it was enabled when you last left the app, logging resumes automatically on the next startup.

Gain tip: This app is sensitive to signal strength. If nothing decodes, try starting with AMP 0, LNA 32, VGA 20, and adjust from there. Both over-amplification and under-amplification will prevent decoding.

Common Frequencies

• 433.92 MHz — Europe, most of the world
• 315 MHz — North America, Japan
• 868 MHz — Europe and others
• 915 MHz — North America, Japan

Sensor List

Each row represents one unique sensor. Entries are kept for up to 64 sensors at a time. Columns:

• Type: Sensor protocol name (see Supported Protocols below).
• Temp: Temperature in the selected unit.
• Hum: Relative humidity in percent, or – if the sensor does not transmit humidity.
• Ch: Channel number reported by the sensor, or – if not applicable.
• Age: Seconds since the last packet was received from this sensor. Resets to 0 on each new reception.

Selecting a row opens a detail view with all fields expanded: Type, Id (hexadecimal), Temperature, Humidity, Channel, Battery status (OK / LOW), and Age. Press Done to return to the list.

Logging

When the Log checkbox is enabled, received sensor data is written to LOGS/WEATHERLOG_.CSV on the SD card. The file starts with the header line:

;Type; id; Temp; Hum; CH; Batt

Each subsequent line contains one decoded sensor reading in the same column order.

Supported Protocols

26 protocols are decoded:

Acurite592TXR, Acurite5in1, Acurite606TX, Acurite609TX, Acurite986, Ambient, AuriolAhfl, AuriolTH, Bresser3CH, EmosE601x, GT-WT02, GT-WT03, InFactory, Kedsum, LaCrosse TX, LaCrosse TX141THBv2, NexusTH, Oregon2, Oregon2B, Oregon3, OregonV1, SolightTE44, ThermoPro TX4, TX 8300, Vauno EN8822, Wendox W6726

Settings Persistence

The temperature unit and log state are saved to rx_weather.ini on the SD card when App Settings is enabled in the global Settings menu.
