Bluetooth Tags over Digital Matter devices

We’re really excited to announce that AllThingsTalk IoT Platform now supports Bluetooth Tag devices over Digital Matter trackers.

How it works:

• Digital Matter makes powerful trackers which besides sending its own sensory data (location, speed, altitude etc.) can act as a gateway for nearby Bluetooth Tag devices
• On the other hand, a simple Bluetooth Tag device will transmit its sensory data at all times (e.g: Humidity and Temperature tag, Motion tag, Door opened or closed tag etc)
• If a Bluetooth tag is in proximity of the Digital Matter tracker, the tracker will pick up the transmitted tag data and publish it to AllThingsTalk IoT Platform
• Back in your ground, you will see both devices being updated: the Digital Matter device with its location, speed and altitude, but also Bluetooth tag device, containing its data and appended location from the tracker (it gives a location dimension to otherwise plain tag data)

WiFi and Cell tower fallback for Digital Matter devices

Some Digital Matter trackers offer fallback geo-location options when the device does not have a GPS fix. In this case, the device will first look for any nearby WiFi access points and send these to the platform. The platform will then calculate longitude and latitude and update the asset state. If that is not an option, the device will try to collect cell tower feedback, send these, and the platform would calculate longitude and latitude based on that.

Even if the accuracy of such fallback location data are much lower than a GPS fix, this feature is very handy to know where your device is in indoor situations, or as a general backup.

Bugfixes

• Label widget now rounds numbers to 2 decimals
• Rules with multiple webhook actions work as expected
