Decoding Shelly BLU Distance BLE Data in ioBroker

Introduction

Hey guys! Today, we're diving deep into enhancing the ioBroker.shelly adapter to fully decode the BLE (Bluetooth Low Energy) events from the Shelly BLU Distance device. This is a crucial step for those of you using this nifty device in your smart home setups, as it will allow for more accurate and detailed data interpretation within your ioBroker environment. Currently, the raw BLE event data from the Shelly BLU Distance isn't fully deciphered, which means we're missing out on some valuable insights. Let’s explore what this means, the current state of affairs, and how we can improve it.

The Shelly BLU Distance is a fantastic little device that uses BLE to measure distance, and integrating it properly with ioBroker can open up a world of possibilities for home automation. Imagine being able to trigger actions based on how far away an object or person is from the sensor! However, to achieve this, we need to ensure that the data transmitted by the device is correctly interpreted by the ioBroker adapter. So, let's get started and figure out how we can make this happen!

Current State: The Challenge

As it stands, the BLE events from the Shelly BLU Distance are not completely decoded by the ioBroker.shelly adapter. When the device sends out a BLE event, it arrives in a raw format that isn't immediately understandable. For example, an event might look something like this: 44000b015c2c0040de00. While some values can be extracted, like the distance in millimeters (0x00de which translates to 222 mm), the other values remain a mystery. We have:

  • 0x0044 → 68
  • 0x010b → 267
  • 0x2c5c → 11356
  • 0x4040 → 16448
  • 0x00de → 222 mm distance

These numerical values likely represent different parameters or sensor readings, but without decoding them, we're only getting a fraction of the information the device can provide. This is where our enhancement comes in – we need to figure out what these values mean and integrate them into the ioBroker adapter for a more comprehensive understanding of the Shelly BLU Distance data. By fully decoding these events, we can unlock the full potential of the device and create more sophisticated automation routines.

Understanding the Importance of Decoding

Decoding the BLE events from the Shelly BLU Distance is crucial for several reasons. First and foremost, it allows us to access all the data the device is capable of transmitting. Currently, we're only seeing a fraction of the information, which limits the kinds of automations and insights we can derive. Think of it like trying to understand a book by only reading every fifth word – you'll get the gist, but you'll miss a lot of the detail and nuance.

Secondly, having access to the full data set can improve the accuracy and reliability of our smart home systems. For instance, if the undecoded values represent signal strength or battery level, we could use this information to fine-tune the placement of our sensors or receive alerts when a device's battery is running low. This level of detail can significantly enhance the user experience and make our smart homes truly smart.

Finally, decoding the BLE events opens the door to more advanced and customized automation scenarios. Imagine being able to trigger different actions based on the proximity of an object, the direction it's moving, or even environmental factors detected by the sensor. The possibilities are endless, but they all hinge on our ability to fully understand the data being transmitted by the Shelly BLU Distance. So, let's roll up our sleeves and figure out how to crack this code!

The Suggestion: A Path Forward

The primary suggestion here is to dive into the raw BLE event data and decode the meaning behind each value. This involves a bit of detective work, but it's definitely achievable. Here’s a breakdown of the steps we might take:

  1. Research and Documentation: The first step is to scour the official Shelly documentation and community forums for any information about the BLE event structure of the Shelly BLU Distance. Sometimes manufacturers provide details about the data format, but even if they don't, community members may have already started to unravel the mystery.
  2. Data Analysis: We can collect a series of BLE events under different conditions (varying distances, environments, etc.) and analyze the patterns. By observing how the values change in response to different stimuli, we can start to make educated guesses about what they represent. For example, if a particular value consistently increases as the device gets closer to an object, it might be related to signal strength or distance confidence.
  3. Reverse Engineering: If official documentation is scarce, we might need to engage in some reverse engineering. This involves disassembling the device's firmware or using specialized tools to monitor the BLE communication and understand the data structures. This is a more advanced technique, but it can be incredibly effective.
  4. Integration into ioBroker Adapter: Once we've decoded the values, the next step is to integrate them into the ioBroker.shelly adapter. This involves modifying the adapter's code to parse the BLE event data and expose the decoded values as states within ioBroker. This will allow users to easily access and use the data in their automation rules and visualizations.

By following these steps, we can transform the raw BLE event data into meaningful information, making the Shelly BLU Distance an even more powerful tool in our smart home arsenals.

Adapter Version and Context

Currently, this issue is present in version 10.4.0 of the ioBroker.shelly adapter. It’s important to note that this enhancement is not just a nice-to-have; it’s a critical step in fully utilizing the capabilities of the Shelly BLU Distance. By addressing this, we can ensure that users of the adapter are getting the most accurate and comprehensive data from their devices.

The context here is within the broader ioBroker community and ecosystem. ioBroker is known for its flexibility and extensibility, thanks to its adapter architecture. Adapters allow ioBroker to interface with a wide range of devices and services, making it a central hub for smart home automation. Enhancing the ioBroker.shelly adapter to fully support the Shelly BLU Distance aligns with this philosophy of openness and integration.

Moreover, this enhancement is driven by the community’s desire to push the boundaries of what’s possible with smart home technology. Users are constantly seeking new ways to automate their homes and gain deeper insights into their environments. By decoding the BLE events, we’re not just fixing a technical issue; we’re empowering users to create more sophisticated and personalized smart home experiences. So, let's get to work and make this happen!

Practical Applications and Use Cases

Once the BLE events from the Shelly BLU Distance are fully decoded, a plethora of practical applications and use cases emerge. Imagine the possibilities! Here are a few examples to get your creative juices flowing:

  • Presence Detection: By analyzing the distance data, you can accurately determine whether someone is in a particular room or area. This can be used to automate lighting, heating, and other systems based on occupancy.
  • Proximity-Based Triggers: You could set up triggers based on how close an object is to the sensor. For instance, you could trigger a notification when your keys are placed within a certain distance of the sensor, or automatically unlock a door when you approach it.
  • Item Tracking: Attach a Shelly BLU Distance to valuable items and use the distance data to track their location. This could be useful for preventing theft or simply finding misplaced items.
  • Pet Monitoring: Monitor the location of your pets within your home. You could set up alerts if they leave a designated area or use the data to track their activity levels.
  • Environmental Monitoring: If the undecoded values include environmental data (e.g., temperature, humidity), you could use the sensor to monitor these conditions and trigger actions accordingly. For example, you could automatically turn on a humidifier if the humidity drops below a certain level.

These are just a few examples, and the actual use cases will depend on your specific needs and creativity. The key takeaway is that decoding the BLE events unlocks a whole new level of functionality for the Shelly BLU Distance, making it an even more valuable asset in your smart home setup.
