Just updated from WS3085 to Ecowitt Gw1103.
Very simple to install and link to CumulusMX

Run CumulusMX on Rpi and a PC.
The CumulusMX on the PC is stopped at night and started next morning. Links to Ecowitt.net and downloads all data that was not recorded overnight on the PC. But the average temp in today.ini is not correct.
[Temp]
Low=16.399999999999999
LTime=05:10
High=30.600000000000001
HTime=10:16
Total=260.39999999999998
Samples=9
ChillHours=460.56665712991128
HeatingDegreeDays=0.2777777777777779
CoolingDegreeDays=0.75756944444444407
GrowingDegreeDaysThisYear1=1566.699999827146
GrowingDegreeDaysThisYear2=693.95000066757223

In the CumulusMx on the Rpi shows

[Temp]
Low=11.800000000000001
LTime=04:56
High=31.300000000000001
HTime=11:16
Total=11732.299999999987
Samples=682
ChillHours=460.56665712991128
HeatingDegreeDays=1.3668055555555532
CoolingDegreeDays=0.84895833333333326
GrowingDegreeDaysThisYear1=1550.999999827146
GrowingDegreeDaysThisYear2=683.25000066757229

The Samples and Total values in the PC is wrong.

Both today.ini files attached and MXdiag file from the PC


The min and max temps differ because the Rpi records are in 1min intervals but the PC downloads from ecowitt.net is in 5min intervals, so they must differ.
