Problem with writing values to Google Sheets

I followed a post from this: Writting sensors' values to Google Sheets to write values to Google Sheets.

This is my AppDaemon config:

system_packages: []
python_packages:
  - hass-apps
  - gspread
  - oauth2client
init_commands: []

This is in my apps.yaml

google_sheets:
  module: gsheets
  class: GSheets

And this is my gsheets.py

import appdaemon.plugins.hass.hassapi as hass
import gspread
from oauth2client.service_account import ServiceAccountCredentials
import datetime

class GSheets(hass.Hass):
  def initialize(self):
     self.log("GSheets started")
     runtime = datetime.datetime.now()
     addseconds = (round((runtime.minute*60 + runtime.second)/300)+1)*300
     runtime = runtime.replace(minute=0, second=0, microsecond=0) + datetime.timedelta(seconds=addseconds)
     self.run_every(self.publish_to_gs,runtime,300)

  def publish_to_gs(self,kwargs):
     scope = ['https://spreadsheets.google.com/feeds',
              'https://www.googleapis.com/auth/drive']
     creds = ServiceAccountCredentials.from_json_keyfile_name('/share/googleDriveCredentials.json', scope)
     client = gspread.authorize(creds)
     fmt = '%Y-%m-%d %H:%M:%S'
     d = datetime.datetime.now()
     d_string = d.strftime(fmt)
     state_temp = self.get_state("sensor.solar_power_current")
     state_humi = self.get_state("sensor.solar_power_today")

     sheet = client.open("data").sheet1

     row = [d_string,state_temp,state_humi]
     index = 6
     sheet.insert_row(row, index, value_input_option='USER_ENTERED')

And this is what the log shows:

So I think it misses the gspread module. I am on Hassio, so how do I enable it?

Did you restart the add-on after adding the packages to the AppDaemon config?
