Communication with Lektrico's chargers

LektricoWifi

This is a package for communicating with Lektrico's chargers (1P7K, 3P22K) and devices (EM, 3EM) when they are in your wifi network.

You have to know the IP of your device.

What is this package offering:

1. Identify your device by IP

type, serial_number, board_revision

2. Ready the device's parameters

currents, voltages, powers, errors, ...

see the output in the examples below

3. Command the device

commands for charger:

• start charging: send_charge_start
• stop charging: send_charge_stop
• reset the device: send_reset
• enable/disable authorisation: set_auth with bool parameter
• set leds brightness: set_led_max_brightness with int parameter 10->100
• set the dynamic current: set_dynamic_current with int parameter 0 or 6->32
• set the user current: set_user_current with int parameter 6->32
• lock/unlock the device: set_charger_locked with bool parameter

commands for em:

• set the load balancing mode (OFF, POWER, HYBRID, GREEN): set_load_balancing_mode with int parameter 0->3
• reset the device: send_reset

How to use it:

1. Find the IP of your Lektrico device in your local wifi network

2. Install it in your python project's environment

   pip install lektricowifi==0.0.25

3. Install the required library

   pip install aiohttp

4. Python example for charger: (python 3.11.0)
