To be sur i did it again :
#sudo PYTHONPATH=/usr/share/weewx python
/usr/share/weewx/weewx/drivers/ws23xx.py --readings
Traceback (most recent call last):
File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 2120, in <module>
data = s.get_raw_data(SENSOR_IDS)
File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 797, in get_raw_data
raw_data = read_measurements(self.ws, measures)
File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 2037, in
read_measurements
nybbles = ws2300.read_batch(batches)
File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 1201, in read_batch
self.reset_06()
File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 1070, in reset_06
raise self.Ws2300Exception(msg)
__main__.Ws2300Exception: Reset failed, 100 retries, no response
The station is wired connected.
Solution : buggy libusb/serial in the operating system (typically in older
rpi systems) ???
