Hi All,
Over the past week I have been trying to update my Driver that I use with
my Raspberry Pi3 and GrovePi board.
The problem I have is that it appears to load up and then stops and shows:
Nov 9 23:10:07 RaspiDexmet2 weewx[3252]: engine: Starting up weewx version
3.7.1
Nov 9 23:10:07 RaspiDexmet2 weewx[3252]: engine: Starting main packet loop.
Can anyone please advise as to what I am doing wrong?
I have uploaded at shortened version of my driver,, hope someone may help
solve the problem
Many thanks
Michael
