TypeError: 'NoneType' object is not callable in appdaemon

Configuration

Hi!

I’m trying my first appdaemon script and I get the following error:

Unexpected error in worker for App app_abshum:
Traceback (most recent call last):File "/usr/local/lib/python3.4/dist-packages/appdaemon/appdaemon.py", line 518, in worker
function(ha.sanitize_timer_kwargs(args["kwargs"]))
TypeError: 'NoneType' object is not callable

This is my script. It’s supposed to get some weather parameters, calculate the absolute humidity and set some sensors to the result.

import appdaemon.appapi as appapi
from atmos import calculate
import datetime

class App_Abshum(appapi.AppDaemon):
    def initialize(self):
        time = datetime.time(0,0,0)
        self.run_minutely(self.abshum(), time)
    
    def abshum(self):
        self.p_out  = float(self.get_state('sensor.yr_pressure'))
        self.T_out  = float(self.get_state('sensor.yr_temperature'))
        self.RH_out = float(self.get_state('sensor.yr_humidity'))
        self.p_in   = float(self.p_out)    # self.get_state('sensor.keller_pressure')
        self.T_in   = float(self.get_state('sensor.keller_temp'))
        self.RH_in  = float(self.get_state('sensor.keller_humid'))
        
        abshum_in  = calculate('AH', RH =self.RH_in,  p=self.p_in,  T=self.T_in +273.15, debug=True)[0]
        abshum_out = calculate('AH', RH =self.RH_out, p=self.p_out, T=self.T_out+273.15, debug=True)[0]
        
        self.set_state('sensor.abshum_in',  state=abshum_in)
        self.set_state('sensor.abshum_out', state=abshum_out)
        
        diff_abshum = abshum_in - abshum_out
        share_abshum = diff_abshum / abshum_in * 100.
        
        if diff_abshum > 0:
            self.set_state('binary_sensor.fenster_keller', state='off')
        else:
            self.set_state('binary_sensor.fenster_keller', state='on')
            
        self.set_state('sensor.share_abshum', state=share_abshum)

and this is my appdaemon.yaml

Any idea? :grinning:

Hi there - can you post the whole error in the log please?

That’s the wrong way to use a callback - try this:

self.run_minutely(self.abshum, time)

Ok I changed that. Now I get:

I’m not really an objective oriented python programmer :grinning:

Ok I had to add @staticmethod before my def abshum(self).
I don’t understand but it calls the function now. Hint taken from here:

Now I get the following error:

I thought self.get_state() was the method to use here? Like shown here:
https://github.com/home-assistant/appdaemon/blob/dev/API.md#get_state

What am I doing wrong? Is it because of the @staticmethod that self.get_state can’t call the functions of appapi.AppDaemon anymore?

The 2nd error was because you passed a parameter time to ashbum but you didn;t declare that parameter in the definition ashbum. You do not need to use @static method - that just hides the problem.
