The 2016 solar powered model with 100% wireless remote sensor. This professional weather station features calibration mode for guaranteed accuracy, rechargeable batteries, and detailed adjustable alarms. There is full history for all weather data from the new design remote sensor.
Initially I did have a few issues with the product as the "SET UP" instructions were not all that clear but after contacting your service dept. the unit is now working as expected. I would suggest that the instructions be revisited and brought into line with the workings of the actual product.
