To use the HTU21 or an SHT21, the I2C bus extender chip is not absolutely necessary, but you have to connect your sensor to the connector marked as I2C, not the one marked with SHT2X/EI2C.

Success!! Thanks Werk_AG. That's one thing out of the way. I've changed my WD back to normal again and it is reporting properly now.

If you are using a Davis Wind Vane, don't care about adjusting the R6 pot, it is only used for the the Fine Offset vanes. The JP2 jumper should also be left open.

Thanks for this info. JP2 jumper was already open.

Regarding the wind speed readings, recheck the connections again. Remember that the pin out of the original Davis RJ12 connector, is not compatible with the WeatherDuino Pro2 RJ12 connector. Please do a search on the forum, there is a topic about this matter with a diagram of the required connections.

I had already replaced the plug with an RJ12 plug with the different pin configuration. I couldn't find my crimping tool though, so I just used multi-grips to attach it. I'll have another look for my crimping tool and have another crack at it.

Code:

#define WSpeedSensor_Type 30  

#define WDirSensor_Type  30

This had already been set in the config stage.

There might be a problem with my rain sensor as it just stopped reporting to the Lacrosse station in the last week or so as well. So I don't know if the problem is with the Lacrosse rain sensor, the Lacrosse external unit or the Lacrosse internal unit. It regularly loses the connection so that's all I thought it was, but I haven't been able to get it to report rainfall again.

Thanks for your help Werk_AG.
