Thanks to all who suggested various solutions or approaches. I perhaps was
overly-specific in the original question, saying I wanted to run a script,
when all along the solution was under my nose: there is an example provided
in the standard distro that does, I think, just what I want -
/usr/share/doc/weewx/examples/lowBattery.py
I will dink around with that and report back here if I find anything
significant.
Thanks again,
rob
