And I thought 'reading' the vantage driver was difficult, this one has really made my head spin.
When I first read this on my phone last night the log was very difficult to read and I saw the comment about historical data and was concerned there was an issue with the interval weighting code introduced in 3.7.0, having now read the logs on the big screen as well as the rest of the posts it's clear to me this is not the case and it is a WMR200 driver issue. Thinking aloud here as to what is going on. genStartupRecords() is called on weeWX startup to catch up any archive records. The very first time through, property _pkt is initialised to None and hence the _process_packet_complete() method is not called at line 1897 ( _process_packet_complete() calls self._pkt.packet_process() (ie PacketArchive.packet_process()) which (would) add the interval field to the packet). The _sensor_to_fields() method creates the archive record that is to be yielded, and it would normally add the interval field to the archive record, but since the interval field was not added to the packet vide line 1897, no interval field is added to the archive record that is yielded. The accumulator then chokes when it tries to interval weight the archive record. Solution, something needs to be introduced to add the interval field to the packet in genStartupRecords() after the _poll_for_data() method is called at line 1906. I suspect Tom or Matthew will have the elegant code to do that, besides my head hurts now.
