The outside sensor seems to be fine. I would like to be able to service the fan motor, but haven't tried yet. I am starting to get false lightning out of the sensor, so I'm thinking the fan is noisy due to age. I lost one HD display. The batteries seem to last about 8 to 9 months typically. I would like to be able to use the myacurite to send data places besides WUnderground, that is my main issue with the system.
