Oregon Scientific Sensors

With a solution to intergarting the WH1080 not seeming to be a simple plug and play task....

I got thinking, my house in the UK is ran by homeseer, mainlobby, with an rfxcom ethernet transceiver along with a number of Oregon Scientific temp and humidity sensors to give me room temps etc.

I know Oregon sell a number of weather station solutions too so I bought a WMR80.................. so now how easy would it be to provide a solution for the HAH, well a quick bit of googling provided a jeelabs link which gave the main code providing hex data via the arduino here and protocols:



A bit more searching found some code which should of decoded this into meaningfull results, but didn't out of the box, but after a couple of evenings of re-coding I had it providing temperatures, Hygro, windspeed, direction, rainfall etc. the pde has some issues and needs some work, all I have done is fix the code and added some new sensors, so all credit goes to those who wrote and shared it first.

Does any one have a OWL energy monitor?, as this code has also been provided, not tested so know doubt will need a bit of rework also.

I have attached the arduino code for you to try, modify and share, next step is to write a lua script to parse the data for the HAH.


Added a .txt extension to be able to attach the file so Just delete the .txt file extension

Hope this is of interest

Just for info,

I have tryed a few 433Mhz RX, a cheap flebay unit which looks similar to the jeenodes unit is pants only receives data from sensors that are local, a second RFhope unit that was not OOK caompatable, recently sourced a RX-M50RR30SF as used in the original project and have very good reception


Below is a screendump of the serial output from the arduino with the reworked code

Nice looking RF Rx module

Thanks for the info ... good job Steve.

That module looks very well constructed. 

I tested a fair few cheaper parts when building the HomeEasy RF Rx unit. If you are up for a test, I could send you one of the modules that I ended up choosing ... so you might compare with the RX-M50RR30SF.

RF Rx comparison

I'm up for testing, it would be interesting to see what differences in range the units have.

The cheap fleabay unit marked ZABR1-01 range was only a couple of meters, where the Aurel RX-4M50RR30SF has a good 15m + inside still need to confirm the full distance.
