I have a Wireless Vantage Pro 2, installed January 2013. I noticed a low transmitter battery warning on the console, so I went looking at archive.sdb and pulled out the values to graph.
The first low value was about 0600 on January 6th. Since then, it seems to reset to not-low every day at midnight, not tripping some days, and now tripping much faster after midnight. Last night, there was 1 data point where it was 0, then back to 1. On January 17, it made it to 0340 before becoming 1. I can see how the battery voltage would recover above threshold when the sun was up and it wasn't being used, but midnight doesn't make sense from that viewpoint. Despite all this I seem to have no loss of data. But that may be the difference between a battery being low vs non-functional. I'm going to change the battery and measure the old one; I haven't touched it since installation 7 years ago. I hope it's the battery and not the supercap. I don't see how anything weewx could be doing would cause this midnight effect, as surely these values are in the archive packets. I wonder if anyone else has seen this sort of behavior?
