Import Weather Station WD2000 to Domoticz, Technoline, ALDI
Dev still on going, missing Temperature_Calendar (lot of work to get min, avg and max value / day since all values are hourly) and number of days to import (take all history)
To save batteries, the station WD2000 connects to the Wifi only once per hour (if not connected with the USB cable to power supply). The values are updated every 57 secondes with the USB power supply, the Wifi stays always on in that situation.
You must have installed the smartphone application DirektWetter (Android or iOS), fully setup your Weather Station WD2000, including the user registration. And be sure that you have information uploaded from your station in the application. This information are coming from cloud.technoline.info and DomoticzDirektWetter is using json API to get values.
Note: This script is largely inspired by https://github.com/Scrat95220/DomoticzGazpar with the same approach.
-
In Domoticz, go to Setup/hardware, add or reuse a Dummy Hardware (Does nothing, use for virtual switches only) then create a virtual sensor "Temp+Hum+Baro" for the Station. then create another virtual sensor "Temp+Hum" for the external temp/hum sensor.
-
Then in Setup/Devices, add them to the devices. Mark down the idx to setup in the cfg file.
sudo apt-get install python3 python3-dateutil python3-requests
cd /home/pi/domoticz/scripts/python
git clone https://github.com/ProfBoc75/DomoticzDirektWetter.git
cp _domoticz_direktwetter.cfg domoticz_direktwetter.cfg
nano domoticz_direktwetter.cfg
and change:
[DIREKTWETTER]
# Username and password that you used to register your DirektWetter Application from Android or iOS
USERNAME=youremailaddress@domain.com
PASSWORD=mypassword
NB_DAYS_IMPORTED=10
[DOMOTICZ]
# Domoticz index at least station and sensor1, leave blank others if not yet created
devicerowidstation=domoticz_idx_number_for_station_temp_hum_barometer
devicerowidsensor1=idx_number
devicerowidsensor2=idx_number
devicerowidsensor3=idx_number
[SETTINGS]
# Path to your domoticz.db file
DB_PATH=/home/pi/domoticz
NB_DAYS_IMPORTED is not yet implemented, here for future updates.
Configuration file will not be deleted in future updates.
Manually launch
cd /home/pi/domoticz/scripts/python/DomoticzDirektWetter
chmod +x direktwetter.py
./direktwetter.py
Then check missing python modules and the login credential if they are ok:
DomoticzDirektWetter.log
Go to to your Domoticz web site and check that the both Temperature Devices are updated.
Uncomment the 2 lines at the end of the script (to be improved later with NB_DAY_IMPORTED)
#getHistory(token)
#logging.info("getHistory values successfully!")
Will start every hour at 2 , not before to let the station updates hourly values in the Cloud (under batteries)
2 * * * * /usr/bin/python3 /home/pi/domoticz/scripts/python/DomoticzDirektWetter/direktwetter.py >/dev/null 2>&1
Will start every minute (with USB Power Supply)
* * * * * /usr/bin/python3 /home/pi/domoticz/scripts/python/DomoticzDirektWetter/direktwetter.py >/dev/null 2>&1
In Domoticz, the virtual sensors are selves updated every 5 mn by Domoticz to add Dewpoint but unfortunatly this may add wrong values like sawtooth. I will try to update sensors with the Domoticz json/AP (hope soon) to see if any improvement here.
