[Solved] Read the Output of Phyton

---

Hello,
i wanted to read the value of a temperatur sensor with a phyton script. Im using an unipi with evok and pimatic.
So Pimatic must read the last line of this script and set it as temperatur output:

#!/usr/bin/python
from jsonrpclib import Server
s=Server("http://localhost:81/rpc")
#print s.owbus_list(1)
s.ao_set_value(1,2.6)
print s.sensor_get_value('286E6474060000B7')

Device:

 {
      "id": "Temp1",
      "name": "Temperatur Sensor 1",
      "class": "ShellSensor",
      "attributeName": "value",
      "attributeType": "number",
      "attributeUnit": "C",
      "command": "sudo bash /home/pi/temp.py",
      "interval": 60000
    }

@Betacrypt Does your python script work from the command line, i.e. executing sudo bash /home/pi/temp.py in particular?

For me, this only works if I am using the -c option, for example:

sudo bash -c /home/pi/temp.py

@mwittig Hell Yeah The Output is working.

Im again, now i have a Problem to display the voltage. Putty says:
pi@witro-mauertrockenlegung:/home/pi# ./volt.py
[2.6329486840848064, u’1435578280.7’]

so the voltage is displayed. The script is in phyton too:

#!/usr/bin/python
from jsonrpclib import Server
s=Server("http://localhost:81/rpc")
s.ao_set_value(1,2.6)
print s.ai_get(1)

Device:

{
      "id": "Spannung-outAi1",
      "name": "Spannung",
      "class": "ShellSensor",
      "attributeName": "value",
      "attributeType": "number",
      "attributeUnit": "V",
      "command": "sudo bash -c /home/pi/volt.py",
      "interval": 60000
    }

@Betacrypt Thanks for upvoting

Without knowing the API it is a bit of guess work for me. Actually, the value returned looks like an array of two values. If the first value is the voltage reading you can access this using the index operator, e.g. print s.ai_get(1)[0].

The second value of the array is an unicode string. Maybe the following link on python string encoding is any useful for you. - http://stackoverflow.com/questions/599625/python-string-prints-as-ustring Presumably, you need to set the character enocing at some point.

@mwittig this works very well
