I recently received a 02027A1-RX AcuRite weather station as a gift. Having waited the prescribed period of time for the unit to "settle", I find I am still getting temperature spikes in the morning of anywheres upward of 20 degrees above the actual temperature. The unit does then settle down to the appropriate temperature for the rest of the day. I have placed the unit in several different areas on my boat (I'm a liveaboard) with the same results. Any ideas?
