Dweepy for Dweet
Dweepy for Dweets
- Dweepy is a library that simplifies posting and fetching data from Dweet
Reference
Installing Dweepy
- Open the Terminal and enter the command pip3 install dweepy
- To test dweepy close any existing python environments and reopen them (e.g. Thonny).
- Then test the library in the Python Shell with the command instruction import dweepy

Making a Dweet using Dweety
- Enter the following code and save the file as dweepy_test.py
- Thh folliwng python code first creates a library, then dweets the library to the dweet-thing named 3083-MPPT-Xbee1-test
# Posting data using dweepy
import dweepy
dweet_dict = {}
dweet_dict.update({"Volt": '1000'})
dweepy.dweet_for('3083-MPPT-Xbee1-test', dweet_dict)
Testing to see if the Dweet has been uploaded
- Open a Web browser
- In the Search Bar enter the url
https://dweet.io/get/latest/dweet/for/<My_Dweet_address>
- Replace <My_Dweet_address> with your own address.
- If the dweet has been committed you should see the following in your browser.
Retrieving Dweets using Dweepy in Python
- The following python code pulls information from the dweet and stores the result in url which is also a dictionary type variable.
- Then the individual data components can be extracted, such as Volt
# Getting a dweet using Dweepy
import dweepy
# Get dweet data
url = dweepy.get_latest_dweet_for('3083-MPPT-Xbee1-test')
# Print dweet data set
print(url)
# Extract date time from dweet
dict = url[0]
longdate = dict['created']
print(longdate)
# Extract specific data sets from Dweet
voltage = dict['content'][('Volt')]
print(f'The voltage is {voltage}')
Full code
import dweepy
#https://github.com/paddycarey/dweepy - Reference
# Publish data via a Dweet
dweet_dict = {}
dweet_dict.update({"Volt": '1000'})
dweepy.dweet_for('3083-MPPT-Xbee1-test', dweet_dict)
# Get data from Dweet
url = dweepy.get_latest_dweet_for('3083-MPPT-Xbee1-test')
print(url)
dict = url[0]
longdate = dict['created']
print(longdate)
voltage = dict['content'][('Volt')]
print(f'The voltage is {voltage}')

Adding more data to the dweet_data Dictionary
- To add more data to the dweet_data dictionary following this code example:
dweet_dict = {}
dweet_dict.update({"Volt": '1000'})
dweet_dict.update({"Current": '3.0'})
dweet_dict.update({"Wattage": '75.0'})
dweet_dict.update({"Temperature": '25.3'})
Full code
import dweepy
#https://github.com/paddycarey/dweepy - Reference
dweet_dict = {}
dweet_dict.update({"Volt": '1000'})
dweet_dict.update({"Current": '3.0'})
dweet_dict.update({"Wattage": '75.0'})
dweet_dict.update({"Temperature": '25.3'})
dweepy.dweet_for('3083-MPPT-Xbee1-test', dweet_dict)
url = dweepy.get_latest_dweet_for('3083-MPPT-Xbee1-test')
print(url)
dict = url[0]
longdate = dict['created']
print(longdate)
voltage = dict['content'][('Volt')]
print(f'The voltage is {voltage}')
current = dict['content'][('Current')]
print(f'The current is {current}')
