TA-CMI

A Python wrapper to read out sensors from Technische Alternative using the C.M.I.

How to use package

Json API

CoE Server

Data can be retrieved using this CoE to HTTP server

import asyncio

from ta_cmi import (
    ApiError,
    ChannelMode,
    CoE,
    InvalidCredentialsError,
    InvalidDeviceError,
    Languages,
    RateLimitError,
)

        analog_channels = coe.get_channels(can_id, ChannelMode.ANALOG)
        digital_channels = coe.get_channels(can_id, ChannelMode.DIGITAL)

        for i in analog_channels:
