Re: en changeant la destination des ecritures

Non non je suis sur j'ai recréer 2 BD data_DHT22T.rrd et data_DHT22Y.rrd , tous les fichiers Xml dont dans webdata dossier virtuel donc je les ai effacé et au lancement de ReadDht22.py il se recréent.
Voila avec quoi je crées ma BD

#!/usr/bin/env python
''' this routine will create the rrdtool data base 
 database => data_DHT22Y.rrd
 The data base is used to create chronologic Hygrometrie chart
'''

#first the rrdtool itself
theCMD=['rrdtool','create','data_DHT22Y.rrd']
#start the table from first day of this year
theCMD.append("--start")
theCMD.append("01/01/"+str(datetime.datetime.now().year))
theCMD.append("--step")
theCMD.append("5")
#now let's add all sensors
theCMD.append("DS:{}:GAUGE:1200:-40:125".format('hm_dht22'))
#and now the AVERAGE,MIN,MAX
# last hour 5 seconds 720 points
theCMD.append("RRA:AVERAGE:0.5:1:721")
theCMD.append("RRA:MIN:0.5:1:720")
