Die automatische Berwässerung habe ich abhängig von den Wetterbedingungen und der Temperatur gemacht, ohne Sensor für die Bodenfeuchtigkeit. Hier mal den das Script in Python 2.7:
#!/usr/bin/python
import sys
import os
import requests
import json
import time
from datetime import date
try:
response = requests.get("
http://api.openweathermap.org/data/2.5/weather?id=YOURCITYID&appid=YOURPRIVATEKEY")
x = response.json()
if x['cod'] != '404':
y = x['main']
temp = y['temp']
temp_float = float(temp)
temp_float = temp_float-273.15
temp_float = round(temp_float, 1)
if temp_float == -0.0:
temp_float = 0.0
z = x['weather']
icon = z[0]['icon']
else:
temp_float = 18.0
icon = '01d'
except:
temp_float = 18.0
icon = '01d'
#adjust the amount of the water, depending of the temperature (it's average summer sunrise time at the moment!)
#180s = 1l of water
timer = 270 # 1,5l
if temp_float >= 16.0:
timer = 360 # 2,0l
if temp_float >= 20.0:
timer = 450 # 2,5l
#heavy clouds/overcast, reduce the amount of the water a bit
if icon == '04d' or icon == '04n':
timer = timer*0.75
#rain/thunderstorm, reduce the amount of the water to the minimum
elif icon == '09d' or icon == '09n' or icon == '10d' or icon == '10n' or icon == '11d' or icon == '11n':
timer = timer*0.5
str_on = ""
str_off = ""
while str_on != '1\n':
process = os.popen('sudo ./fritz_on.sh')
str_on = process.read()
process.close()
time.sleep(timer)
while str_off != '0\n':
process = os.popen('sudo ./fritz_off.sh')
str_off = process.read()
process.close()
#write the values to the logfile
today = date.today()
water = timer*0.00556
today_str = str(today)
icon_str = str(icon)
temp_str = str(temp_float)
water_str = str(water)
line = today_str + "," + icon_str + "," + temp_str + "," + water_str + "\n"
f = open('logfile.csv','a')
f.write(line)
f.close()
Natürlich dokumentiert mit schönem Diagramm:
