Our house came with a weather station, which was really cool since I've always wanted one. But, it wasn't working - the transmitter wasn't transmitting. A neighbor who had done some work around the place said he thought the solar panel wasn't recharging it*, as he had to keep replacing the battery. So I hadn't done anything about it.
Posts such as this one make me want to buy one.
Then as I was reading down through I thought I recognized the name of the one I have, so I checked it out. Yes, I have a Davis Vantage Pro 2. So I guess I will figure out what's wrong with it, even if it means buying some new parts for it.
*after doing some research it turns out that the solar panel charges a capacitor, and the non-rechargeable battery is only for backup in case you don't get enough sun.
