Sibo Tablet + ophaalkalender goodness

I recently did a complete renovation where now my complete house is running on HomeAssistant (including all lights, climate control, … ).

One thing I’m happy about is a Sibo tablet that I’ve build in (https://www.alibaba.com/product-detail/SIBO-Customized-Android-Wall-Mount-Tablet_60366060799.html?spm=a2700.7724857.normalList.46.5dd568eaxYjRIL)

Now, each time I need to put out the trash, the tablet shows a red background (see picture). If there is a birthday, it’s green.

It works as follows:

  • I have some automations that create persistent notifications (e.g. when I need to put out the trash or there is a birthday)
  • I wrote a custom android service that listens to the html 5 server sent events from homeassistant and which then turns the correct background on

Hi there @rdehuyss ,

Is there any way you could share how you did the html 5 sending events?

Hi @Vasco,

HomeAssistant has everything build-in: https://developers.home-assistant.io/docs/en/external_api_server_sent_events.html

Is this enough to get you started? I did not experience any problems with the api…

How can you control the gpio’s on this tablet? Can anybody help me with this?

There is a library you can use to do so. I contacted the seller and they gave it to me immediately. I don’t know if I can share it myself though.

Can you copy a part of your configuration to show me how you did?
I have mailed sibo to see what they have.
Thanks for your reply.

I subscribe to the server sent events of homeassistant. This is the code in the eventlistener:

package com.example.hassbackground.service;

import android.app.smdt.SmdtManager;
import android.util.Log;

import com.here.oksse.ServerSentEvent;

import org.json.JSONArray;
import org.json.JSONObject;

import java.util.Date;

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class HassEventHandler implements ServerSentEvent.Listener {

    private SmdtManager smdtManager;
    private Date lastMessageDate;
    private Date lastHttpGetDate;

    public HassEventHandler(HassService service) {
        this.smdtManager = SmdtManager.create(service);
        try {
            checkForNotifications();
        } catch (Exception e) {
            Log.e("HassService", "Error", e);
        }
    }

    @Override
    public void onOpen(ServerSentEvent sse, Response response) {

    }

    @Override
    public void onMessage(ServerSentEvent sse, String id, String event, String message) {
        Log.i("HassBackground", event + " - " + message);
        this.lastMessageDate = new Date();
        if(message.equals("ping")) return;
        try {
            JSONObject jsonObject = new JSONObject(message);
            if(jsonObject.getString("event_type").equals("state_changed") && jsonObject.getJSONObject("data").getString("entity_id").startsWith("persistent_notification")) {
                checkForNotifications();
            }
        }
        catch (Exception e) {
            Log.e("HassBackground", "MessageError", e);
        }
    }

    @Override
    public void onComment(ServerSentEvent sse, String comment) {

    }

    @Override
    public boolean onRetryTime(ServerSentEvent sse, long milliseconds) {
        return false;
    }

    @Override
    public boolean onRetryError(ServerSentEvent sse, Throwable throwable, Response response) {
        return false;
    }
