Thanks, Allan.

I'm trying to understand whether I should build the Pro2 PLUS or the standard Pro2.

In terms of technical architecture, I think it could make more sense for me (others will have different use cases) to keep the RX basic, just working as an RX, and have extra functionality like data display, longer-timescale data logging, wifi/internet upload, etc on a more powerful machine like a Raspberry Pi. Interesting. I'm undecided.

I think that's very wise, John. I would recommend anyone thinking about the WeatherDuino should:

1. Remember that this is NOT a "plug and play" system. It requires at least a sound understanding of electronic design and construction techniques and the ability to solder small components accurately.
   
2. Think, as you are, about what it is you want to achieve as it varies enormously. Some people here want to be able to see from the comfort of their house what the weather is outside. One of our Australian friends however are keeping an eye on an entire farm including weather conditions for the remote landing strip, another is monitoring the water level in the supply tank as well as weather conditions and there are all kinds of ideas in between. As I said this is a *very* versatile system...!
   
3. Once you've decided, carefully PLAN your station. Issues such as the distance that cables must run to sensors, where the outside transmitter will be located and powered etc. will be important considerations when you build.
   

The WeatherDuino tx is obviously the source of all information which it (or "they" - you can use several tx units if necessary) can gather from a wide range of sensors. The rx units, equally obviously, receive the information and so is essential whether you only only want to display it locally or upload it to websites (using either a PC or Raspberry Pi) as a number of us do, usually using the superb Cumulus software - these, including my own, are all "WeatherDuino powered" sites:

In my case, I'm currently using a v5.02 rx board with a 4x20 LCD character display. Along the transmitter it has been working perfectly for well over a year now. I've decided to upgrade to the PLUS board partly because of the increased functionality which the Meduino Mega provides, but also because of the much easier to use touch LCD digital display. "Your mileage may vary" though, as they say!!

I hope this is helpful and I've not been trying to tell you things you already know...
