Hello,
In reference to my last post, I am now happy to report that I have now setup and installed the Oregon Scientific WMR-88A Weather Station!
Installation was a breeze! (Excuse the pun)
After unpacking and taking a quick look through the ‘Quick Setup Guide’ provided, I was soon aware of just how easy it would be to setup!
I installed the Oregon Scientific WMR88 Thermo-Hygro Sensor Unit within around 15/20cm of the La-Crosse Sensor Unit – See Pic Below:

With that installed, I hooked up the Base Unit to the Mains with the provided AC Adapter and installed the supplied batteries in the Themo-Hygro Sensor Unit.
I checked the Base Unit and it had immediately picked up the Signal from the Sensor Unit!
It is worth noting that the Oregon Scientific is ‘Wireless Only’ Transmission where as the La Crosse is both ‘Wireless and Wired’. I use a Wired connection for the La-Crosse.
Next was the installation of the Oregon Scientific Tipping Rain Bucket within 10/15cm of La-Crosse Tipping Bucket – See Pic Below:

Once installed, I tested the Rain Bucket by pouring a Tiny Amount of Water into the Notably Wide Surface Capture Area and was happy to see that the Base Unit was displaying recorded Rainfall, so I then knew it was working properly.
It is worth noting that the Oregon Scientific is ‘Wireless Only’ Transmission where as the La Crosse is wired only.
I use a Wired connection for the La-Crosse.
Finally left was the installation of the Oregon Scientific Wind Vane and Anemometer onto the Roof, within close distance of the La-Crosse Sensors.

Attaching the Oregon Scientific and La-Crosse Wind Sensors was very easy. This is thanks to a simple click, lock and U Bolt System for the Oregon Scientific and a U Bolt System for the La-Crosse (La-Crosse Wind Sensors are already attached to mounting bracket).
You will notice that the La-Crosse has a different Wind Anemometer to the Oregon Scientific.
The La-Crosse uses a Turbine to measure and record Wind Speed where as the Oregon Scientific uses a 3 Wind Cup Setup.
I’ll keep you posted on any differences I see.
And I think thats just about it! Stay tuned for more updates!
