Cumulus Support

hi, I recently installed an ecowitt with gw2000 with latest firmware 3.1.3, but cumulus does not detect rain (which is present on the ecowitt cloud). From the logs I read this: PrintSensorInfoNew: Error - Object reference not set to an instance of an object.
How can I solve it?
Thanks in advance !

Could you please supply the complete MXdiags file for context? Zip up and attach to a reply to this topic.

so, i've setting up the rain amount manually then i've reboot cumulus and this is the latest log file. The rain amount is now reset to zero after the restarting of cumulus

i've correct some errors, for example the -7,5 value at today.ini , then i've add some amount of rain on the gw2000 (for simulating the rain ) , but nothing is recorded. This is the new log file.

I downgraded to version 3184 because I was having too many issues with the Saratoga template. In any case, I think I did something stupid during the installation, as it automatically recovered all the accumulation from the previous day at midnight and is currently recording rain. Thank you for the assistance.
