July 2019 Release Notes

Release date: 31st July 2019

What’s new

Rules engine

We’re introducing our new rules engine - Earl!

Earl

It’s been redesigned from ground up to let you create simple automatic logic effortlessly, and make creating complex logic possible.

Using our drag and drop rule designer, you will be able to mix and match different components to create rules that fit your usecase.

In our old rules wizard, you could actuate a device when your assets changed state (either every time, or when a certain threshold was reached), and you could send a notification to yourself. You could also do both of these actions at preset date and time.

Rule designer

With Earl, you can do all of that, and more!

  • You can do multiple comparisons, such as “when my bike is moving, but it’s also locked” - in essence, detecting theft.
  • You can spice up your notifications with asset states, like “Oil temperature CRITICAL at 110°C” - where 110 is taken directly from temperature asset’s state.
  • You can act on multiple triggers, and you can trigger multiple actions.
    • Want to open your blinds every morning, but also manually whenever you hit a button? You got it.
    • Want to turn off all devices in your house at a press of a button? You can.

Oh, and all of your existing rules are now migrated to Earl.

We’re launching Earl with 3 components - Notify, Comparison, and Day & Time. Go try all of them, and stay tuned, because we will be releasing more!

ABCL

Greetings, LPWAN enthusiasts! We have released improvements to ABCL!

  • Parsing custom JSON is now supported through ABCL. Instead of selecting parts of the binary payload, you can now select fields from the JSON payload.
{
  "sense": [
    {"asset": "temperature", "value": {"json": "t"}}
  ]
}

The code above will take the payload like `{"t": 23}` and use it to set the `temperature` asset’s state to `23`.
  • Full payload retrieval is now possible using $payload selector. To get it, you will need to use an array asset. Its value will be set to the array of bytes representing the payload.
{
  "sense": [
    {"asset": "fullPayload", "value": "$payload"}
  ]
}
  • Multiple gateways registered in LoRa uplinks are now handled more gracefully
    • RSSI and SNR will be returned for the gateway with best values (lowest noise, best signal)
    • Data from all gateways (and everything else supported by a specific NSP) is now available in $metaAll. An object asset needs to be used to hold this value.
  • Spreading factor and Bandwidth are now available with $metaSF and $metaBW, respectively.

For more details, please consult the ABCL specification at https://docs.allthingstalk.com/dl/AllThingsTalk_Binary_Conversion_Language_1_1_0.pdf

Debug persistence

We have updated the device debugger so that it keeps your debug logs between sessions.

No need to curse at heavens next time you refresh the debug window by accident!
