A powered hub makes it just as bad, and possibly worse, Tom. But, with your "more forgiving" Vantage driver, it is far better than before. So I am quite willing to live with it as it is.
As mentioned in the same thread, I removed my cron job that calls a program, and I'm using the tags you recommended based on the NOAA generation template. That's a far better approach. - Paul VE1DX On Wednesday, May 18, 2022 at 9:38:17 PM UTC-3 Graham Eddy wrote: > i reported earlier that i got a burst of weewx restarts by vantage driver > when my extra vp2 station (wireless temp) battery started reporting low (i > hadn’t noticed until this thread started). tom’s new retry patch not > applied. this happened a second time recently viz. burst of restart > activity when extra station reported low battery. nothing to do with power > supplies or reboots, i am more inclined to point to an envoy or data > logger/usb firmware bug (they are more than 15yo). > (it is possible this firmware bug could lead to phantom battery low > reports; i think more likely they were genuine battery low events driving > the error) > > sadly this extra wireless vp2 station has just been borked - it was under > water for a week in 2010 floods (i mounted it higher after that :-) but a > few days ago couldn’t survive 2-3 tonnes of tree branch crushing it on > rocks. it will be replaced by a much much cheaper ecowitt remote temp probe > (i run dual vp2/gw1000) > > On 19 May 2022, at 1:09 am, Paul Dunphy <foc...@gmail.com> wrote: > > Whatever it is, it's related to RPis talking to a Davis Logger via > USB.
