1) Units with WiFi capability can upload data directly to Weather Underground (WU) using an existing WiFi access point. For those who just want to upload their weather station data to WU, this feature makes these units truly stand-alone devices. No need to connect it to any type of computer.
WiFi capability also allows other features such as sync system time with NTP servers, check online for latest available software, upload Air Quality data to ThingSpeak or to your own server.

Which WeatherDuino receiver is best for me?

All WeatherDuino receivers emulate the Davis Vantage Pro communication protocol, and receive data from the same WeatherDuino Pro2 Transmitter units. The main difference between these systems is the Receiver capabilities, which is related to the hardware used in each of them. Below is a brief description of each system. For a more detailed info on each model, please read the Wikis of each model.

WeatherDuino Pro2 (Out of Production)

  • This receiver uses an Arduino Nano as microcontroller.
  • Weather data is shown on an 20×4 LCD display, not a color TFT display.
  • The receiver does not establish a direct connection to Internet, which means you need to keep it connected to a computer (PC or Raspberry Pi) running Cumulus (CumulusMX or any other weather software), even if you only want to upload data to Wunderground.
  • This model cannot receive data from WeatherDuino Air Quality Monitor devices.
  • Compatible with 4Pro Wireless Display units (RF Mode).

WeatherDuino Pro2 PLUS (Out of production but still fully supported - Very few PCB's available)

  • This receiver uses a more powerful AT Mega 2560 microcontroller, installed in a removable Meduino Mega2560 Pro Mini module.
  • Weather data is shown on a 2.8” colour TFT display. Navigation between the available data screens is done by touch.
  • The receiver includes an WiFi module (ESP8266) allowing it to establish direct connection to the Internet via an existing WiFi access point. This capability allows direct data upload to Wunderground without the need to connect to other equipment.
  • It is also possible to use a USB connection to a computer (PC or Raspberry Pi) running any weather software.
  • Can receive data from WeatherDuino Air Quality Monitor devices, and upload them to ThingSpeak, or even your own server.
  • Compatible with 4Pro Wireless Display units (RF and WiFi mode).
  • Has a useful mini web-server which can be accessed from anywhere on your local network, allowing a quick visualization of all weather data, including the state of the Transmitter Units.

WeatherDuino Pro2 Compact

Released in May 2018. It is supplied ready assembled and tested.

  • Very fast operation, due to its 32 bit 80Mhz microcontroller.
  • Supplied fully assembled including the TFT display, Barometric and Temperature / Humidity sensors (BOSCH BME280)
  • Support accent characters on the user interface.
  • Compatible with 4Pro Wireless Display units (WiFi mode).
  • Low power consumption (less than 250mA peak) allows it to be powered directly from the computer USB connection, or when is stand-alone mode, by any micro-USB phone charger.
  • Small size, robust and compact construction. Supplied ready to use (after initial programming).

WeatherDuino 4Pro Dual Band Receiver

This is the newest member of the WeatherDuino receiver family. It is supplied ready assembled and fully tested.

Available in August 2021. More info soon.
