Transfer the following files/folders to the root directory (using Thonny IDE or similar):

• config.py
• locale
• main.py

Create a lib folder within the root directory and copy the following libraries there:

• microdot: Copy the files scr/microdot/__init__.py and src/microdot/microdot.py into the lib/microdot directory.

Open the file config.py and set your WIFI credentials and hostname.

# Example
WIFI_SSID = "your ssid"
WIFI_PASSWORD = "your password"
HOSTNAME = "meter"
WIFI_COUNTRY = "it"

Connect to the device using a web browser at http://<hostname>. Replace <hostname> with the value set in config.py.

See http://<hostname>/data for JSON data.
