On 27.04.17 0420 GMT my bridge rebooted and apparently loaded a new firmware. After the reboot, calculated sea-level pressure being reported to various networks jumped up by aprox. 6hPa. On 27.04.17 1300 GMTthe bridge rebooted again. After this reboot, the slp dropped by about 4.2hPa.
Does anyone else see this on there station? This seems to be related to the reboots and/or firmware updates. Right now the bridge is showing firmware date Apr 26 2017, build 11140.
