Get your BLE sensors data into Home Assistant in 5 minutes

You can now upload your board directly from the web browser!

So let's imagine you want to read data from a sensor like a Mi Flora, an LYWSD03MMC, a weight scale, or any other BLE sensor from this list

That's it, OMG is now loaded into your ESP32 board without Arduino IDE, platformIO or a binary flasher.

Here are the steps in images:

Now comes the Home Assistant part:

Create a user and a password (Configuration->Users) without administrator right for the gateway

Well, this is enough for Home Assistant.

So let's now connect both:

Check the Wifi Access points available with your smartphone
Search for one named OMG_something or OpenMQTTGateway
Connect to it
Enter the following password "your_password"
Select the wifi you want the gateway connected to
Enter the wifi password
Enter the home assistant server IP address (mqtt server)
Enter the username and password created before (mqtt user and mqtt pass)
You can let the other fields as they are unless you want to apply special parameters or security aspects
Click on save

Let's check the middle man (MQTT broker)

Download and Open MQTT explorer
Connect to Home Assistant server, you can create another user as you have done for the gateway
Check the messages received

And finally, see the magic in Home Assistant:

For sensors:

For gateway:

Without any added integration than MQTT, without touching yaml, you get the gateway and the sensors into the device list!

Thanks, Home Assistant for the inspiration in adding the web flasher option!
