Gary, thanks for that clarification. I'll have a look at the new feature if it will be released in the next weewx point release.
As there there seems to be a rainRate software computation available, maybe this could be copied and rainRate substituted by hailRate to get the hailrate working working? This would be a workaround and maybe not to difficult to patch and fit my needs...but I know it would be wiped out with a new update of weewx.... I think at the moment I'm not skilled enough to write a service for the missing hailRate.... Where can I find the rainRate software computation in wewx? Regards, Christian Am Freitag, 26.
