I have a WH1090 station. A month ago I replaced the sensor on the energizer lithium batteries. A day later, unexplained spikes occurred outside temperature to within 1 deg C. Now every day I have the jumps at different times of the day. The station was repaired, but there does not have solved this problem. Jumps are recorded with the disconnected rain sensor and anemometer. I opened the sensor, but everything looks OK. Any suggestions?
