RSI- Funny you mentioned it. I was just talking to gmviso about the same thing. So I apologize for coping and pasting the info from the email we just shared.
I lost the transmitter during a nearby lightening strike, but purchased a replacement via
www.AmbientWeather.com (915 MhZ) And after a week of recent rain the batteries went low due to lack of sun. (Solar charger included on the model I purchased). Other than that I love it being wireless to the console. (good for up to 300ft) I have mine mounted on roof and transmitting to the upper floor of house about 40’ away. The weatherhub2 pushes me emails if I have a problem. I transmit to 5 different weather sites. Two of those sites now have a webcam connection made through my Blue Iris software (FTP).
In additon, I've had the unit for about 4 months.
