Concerning the error with local variable ‘time_start_vt’ , I am not 100% sure, but it may indicate that the belchertown script try to generate a chart of an observation that is not in your weewx database.
Could you share your graph.conf file as well as your weewx.conf file ? Le lundi 16 février 2026 à 23:20:17 UTC+1, O S a écrit : Hello again, Tom, OK, that worked! It ended up that it was in graphs.conf, which makes sense when you look at my first post here :) Brilliant - thank you again. One issue, I now have this when generating a report with: sudo weectl report run Belchertown: Traceback (most recent call last): File “/usr/share/weewx/weewx/reportengine.py”, line 248, in run obj.start() File “/usr/share/weewx/weewx/reportengine.py”, line 465, in start self.run() File “/etc/weewx/bin/user/belchertown.py”, line 2948, in run series_data = self.get_observation_data( ^^^^^^^^^^^^^^^^^^^^^^^^^^ File “/etc/weewx/bin/user/belchertown.py”, line 3722, in get_observation_data time_start_vt, time_stop_vt, obs_vt, start_ts, end_ts, aggregate_interval ^^^^^^^^^^^^^ UnboundLocalError: cannot access local variable ‘time_start_vt’ where it is not associated with a value So, I will try to figure this one out now!
