There is indeed such a limit. The observation types extraTemp1 through extraTemp7 are defined, but anything beyond that, are not. It's very easy to add more. Put the following in user/extensions.py:
import weewx.units weewx.units.obs_group_dict['extraTemp8'] = 'group_temperature' That should be all you need. -tk On Thu, Jan 18, 2018 at 3:36 PM, <[email protected]> wrote: > Hello, > > Just a bit of background: I currently have a VP2 and I recently bought a > WS3000 with 8 sensors to monitor the inside temperature in various places. > What I would like to do is to store all the data in the same database.
