Ok thanks - that fixed the problem. Actually, I got a bit frightened, because at startup, I got:
... Jan 21 18:22:19 vegan python2[25172]: weewx[25172] DEBUG weewx.manager: recalculate_weights: Tranche size 100 Jan 21 18:22:32 vegan python2[25172]: weewx[25172] ERROR user.wmr200: read_device() USB Error Reason:[Errno 110] Operation timed out But, I checked the weather station is there : $ lsusb Bus 001 Device 005: ID 0fde:ca01 Oregon Scientific WMRS200 weather station ... And actually, it seems after a while that it is working: Jan 21 18:26:44 vegan python2[25172]: weewx[25172] DEBUG user.wmr200: Queuing archive packet rx:63 archive_queue_len:1 Jan 21 18:26:45 vegan python2[25172]: weewx[25172] INFO user.wmr200: genStartup() Still receiving archive packets cnt:62 len:1 ... Jan 21 18:26:44 vegan python2[25172]: weewx[25172] DEBUG user.wmr200: Queuing archive packet rx:63 archive_queue_len:1 Jan 21 18:26:45 vegan python2[25172]: weewx[25172] INFO user.wmr200: genStartup() Still receiving archive packets cnt:62 len:1 So, probably just an initial startup error. Thanks for your help!
