Custom Component to get an entity state via the API

Development
1

Hi,

I used to have a custom component that used the home assistant API to parse my entities states and return the state of a single entity via a local URL.
So for example

this query -> https://myinstance:8123/textapi/state/entity_id?api_password:xxxxxxxxx would return the state value of the entity (e.g On, Off, etc)

It used to work perfectly on my version 0.75 hassio.

However now that I have it updated to the 0.82 version it doesn’t work anymore and my custom component fails to load.

Here’s my log errors :

2018-11-27 17:58:00 ERROR (MainThread) [homeassistant.loader] Error loading custom_components.textapi. Make sure all dependencies are installed

I read somewhere that it may be because the homeassistante.remote module is not supported anymore.
So does anyone know any workaround ? Thanks

Here’s my custom component python script (feel free to use it if it’s useful for someone)

import asyncio
import json
import logging

from aiohttp import web
import async_timeout

import homeassistant.core as ha
import homeassistant.remote as rem
from homeassistant.bootstrap import DATA_LOGGING
from homeassistant.const import (
    EVENT_HOMEASSISTANT_STOP, EVENT_TIME_CHANGED,
    HTTP_BAD_REQUEST, HTTP_CREATED, HTTP_NOT_FOUND,
    MATCH_ALL, URL_API, URL_API_COMPONENTS,
    URL_API_CONFIG, URL_API_DISCOVERY_INFO, URL_API_ERROR_LOG,
    URL_API_EVENTS, URL_API_SERVICES,
    URL_API_STATES, URL_API_STATES_ENTITY, URL_API_STREAM, URL_API_TEMPLATE,
    __version__)
from homeassistant.exceptions import TemplateError
from homeassistant.helpers.state import AsyncTrackStates
from homeassistant.helpers import template
from homeassistant.components.http import HomeAssistantView



DOMAIN = 'textapi'

def setup(hass, config):
    hass.states.set('textapi.world', 'Vince')
    """Register the API with the HTTP interface."""
    hass.http.register_view(TextAPIStatusView)
    hass.http.register_view(TextAPIEntityStateView)
    return True


class TextAPIStatusView(HomeAssistantView):
    """View to handle Status requests."""

    url = '/textapi/'
    name = "textapi:status"

    @ha.callback
    def get(self, request):
        """Retrieve if API is running."""
        return web.Response(text="Hello, api text world !")


class TextAPIEntityStateView(HomeAssistantView):
    """View to handle EntityState requests."""

    url = "/textapi/states/{entity_id}"
    name = "textapi:entity-state"

    @ha.callback
    def get(self, request, entity_id):
        """Retrieve state of entity."""
        state = request.app['hass'].states.get(entity_id)
        if state:
            return web.Response(text=state.state)
            # return self.json(state)
        # return self.json_message('Entity not found', HTTP_NOT_FOUND)
        return web.HTTPNotFound(text="entity not found")

Thanks for your help
