My own project is a homebuilt "Solar Sensor" that is "Fully Compatible" with the FO "Solar Pod" (i.e. it will transmit the standard 8-byte FO data packet). It might be possible to arrange my software to also transmit WeatherDuino format data (when I discover what it is), but that will be ever further along my (very slow) development path.
Hi Alan,
For data transmission WeatherDuino uses the Arduino VirtualWire library.
Basically messages are sent with a training preamble, message length and checksum. Messages are sent with 4-to-6 bit encoding for good DC balance, and a CRC checksum for message integrity.
Payload message can be up to 80 bytes.
You can find more info about it here:

Currently I know nothing about the FO protocol, but if possible with the receiver already used, maybe in future I could make something to make the WeatherDuino compatible with your Solar Sensor.
