Hello everyone!
I found this interesting product / forum while looking for information about a project that I have in mind for a while.
I own an Oregon Scientific WMr200 that after a few years of service begins to have problems (both console and external sensors) and use the SW Weather Display to download data. My purpose is to create with Arduino:
A sensor decoder / emulator (so that I can build it myself) --> more or less I succeeded
An oregon (or any other station) console emulator that allows me to continue using the SW Weather Display because I've created ad-hoc VBscript for this SW; I found some article on the serial protocol of an old Oregon station, but Wheather display does not recognize it --> I have not idea how I can do...........
I tried to load WeaherDuino_Pro2_RX on Arduino nano hoping to send something serial, but I did not have any output (and I do not know if it's normal ...)
Studying the weatherduino SW I failed to understand the part of Emulation VP and I would like to ask if anyone can help me and / or address me on some similar project .....
Thanks so much,
Federico

Yes its normal. It just sends data in reply to Davis commands issued by your weather software (Cumulus or Weather
Display).

Thank you Werk_AG for your reply!
The test I implemented was run with open Weather Display and selecting Davis (attached image of the used setup) but I did not have any output from Arduino ... As soon as I have time, I will also try with cumulus to see if it is a configuration issue or something else ...
Can any help be available to understand the part about Davis emulation?
thanks a lot!
Federico

Hi Federico,

Davis have excellent documentation about the Davis Vantage serial protocol , you can find it here:
http://www.davisnet.com/support/weather/...s_v261.pdf

After understanding the protocol, understanding the emulation, is just a question of spending some time looking to the code.

The WeatherDuino Pro2 doesn't allow connection with any weather software, before it was able to received data from some sensors attached to one or more TX units. For testing purpose, you can bypass this behaviour, running the software in test mode.

Hi,

Weather Display works OK with Weatherduino, it is unlikely to be WD causing the problem.

Trial with Cumulus if all else fails.
