# 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

# 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')

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}')
