Where does your service MyEvapCooler sit in the list of services to be run
by the engine? You probably want it at the end of process_services. I don't
know what file it's in, but say it's in myevapcooler.py, then you'd want:
process_services = weewx.engine.StdConvert,
weewx.engine.StdCalibrate, weewx.engine.StdQC,
weewx.wxservices.StdWXCalculate, user.myevapcooler.MyEvapCooler
