Before I pulled the trigger and switched drivers from Simulator to Davis Weather Monitor II (wmII.py) I took a look at the code. Upon inspection it appears that the wmII driver can not access the hardware logger archive records since there is no genArchiveRecords method, just genLoopPackets. So unless I'm mistaken my migration plan won't work because any records stored in the logger while weewx is stopped will be ignored and lost. Admittedly my understanding of the weewx architecture is beginner level so if I am wrong please let me know.
So I can either (a) live with loop packets only, (b) modify the wmII driver, or (c) migrate my historical data on-the-fly. Or perhaps I am putting too much emphasis on the logger capability. I just think it is a nice feature to utilize if it is provided in the hardware. On Wed, Jan 25, 2023, at 3:59 PM, Wayne wrote: > Fantastic! Thank you, Tom. I am sure glad I posted to the group.
