First: many thanks to the author(s) of weewx! My station: RPi2 and Davis Vantage Pro 2. More or less standard skin: https://www.puk2000.de/wetter/index.html.
These days I tried to add data from a new PV system. I can get all relevant current data from the Tesla Powerwall 2 API: Battery Status, Solar Power, House Power, Grid Power, Battery Power. After trying to understand the extensive documentation and getting at least a bit familiar with Python I started the hopefully simple way. Added a service to retrieve the Tesla data und put these data into existing, but unused Davis fields: extraTemp1 to extraTemp5. After changing the unit_group for these items in units.py everything looks pretty well. Only the sample period of the davis (900 seconds) is less than optimal and it seems to me, that there are no archive records for extraTemp4 and extraTemp5. My idea for a better solution is a separate driver for the solar data with a sample period of 10 seconds or so and add new types to the database, to keep the Davis stuff untouched. According to the docu weewx would do the avaraging between reporting periods. Now my questions to the gurus: For my current solution: can I add extraTemp4 and extraTemp5 to the archived items? For the other way: is it possible to use more than one driver in a single weewx instance?
