OverView
GadgetKeeper provides a simple development environment, robust APIs and worry-free hosting, you can accelerate your application development and take advantage of simple scalability as the application and the number of your devices grows.
You can easily integrate your application with external IT systems through our powerful APIs, web services, and a completely hands-free hosting environment that automatically scales to meet any demand, whether you’re serving several devices or several million.
Key FEATURES
REACH THING MODEL:
PROPERTIES, METHODS, EVENTS, TRIGGERS
Use a full object model for your things including properties, methods, events. Things are not just “data logging” entities, but they are smart objects that interact with each other and the world. Properties/methods can be handled by thing or by its server-side proxy, events can be fired by thing or by server side proxy
SERVER-SIDE JAVASCRIPT
Use JavaScript to program your server side logic – whenever it’s a property, method or event trigger. From your JS code you can fire events, call methods and properties or call external systems.
FLEXIBLE EVENT HANDLING
Thing events are easy to handle by creating event listeners (triggers). JavaScript can be used to define complex event handling logic.
Event and time series storage
All events fired by thing are recorded to event storage. Numerical values are extracted and saved to time series.
Multiple communication protocols
Multiple protocols are supported to allow communication between thing and platform: REST, JSON-RPC over TCP socket, JSON-RPC over HTTP, JSON-RPC over MQTT.
Integration with external services
We support a powerful server-side API to interact with external services such as email, HTTP, SMS.
How it works
Model your device’s characteristics
with properties, methods, and events
Connect your device to the
GadgetKeeper API using HTTP,
TCP, or MQTT
Send updated information from
the device directly to the server
Control, integrate, and manage
your devices remotely
Monitor using dashboards
and log
Process and record information.
Define triggers to react to events.
Core Concepts
THING
In the GadgetKeeper a Thing is used to model internet services and real-world gadgets, such as electronic devices, appliances.
THING MODEL
Thing defined as any physical object or entity that has attributes and behaviours associated with it.
THING PROPERTY
Any definite physical attribute or behaviour that can provide inforamtion about the state of the Thing.
Each property in GK must have a data type. There are three types of properties:
- persistent – a property value in the GK database that maintains a set value between function calls.
- script – Set/get function calls are implemented by JavaScript function in GK.
- remote – GadgetKeeper forwards property set/get request to Thing, and then Thing sends property value back or updates it.
THING METHOD
Defines the procedure for an action to be implemented by Thing. Any request/response data types may be optionally defined for each method.
-
There are two types of methods:
- script – method is implemented by JavaScript function in GK.
- remote – GadgetKeeper forwards a request to Thing, and then method is implementd by Thing.
THING Event
Events are activated by a remote call from Thing or from a script property/method in GK, which casuse a state change.
THING Trigger
Causes an action (such as send email) to be executed in response to particular Event. Trigger logic is coded in JavaScript.
THING Schedule
Defines cron-based schedule to execute a method or cause an event.
THING Connection
Defines the communication protocol between GadgetKeeper and Thing.
The GK platform uses the JSON-RPC 2.0 protocol.
which is a simple remote procedure call protocol that supports MQTT/TCP/HTTP/STOMP/XMPP as the transport mechanism.
Api Key
Used to enable API interactions on GadgetKeeper, and allows access to properties, methods, events, etc. of selected things.
Dashboard
Used to enable API interactions on GadgetKeeper, and allows access to properties, methods, events, etc. of selected things.
Data Type
Identifies one of various types of data, such as float, integer or boolean, that determines the possible value formats for data.
Three groups of data types are supported: primitives arrays structure
Template
A base model used for a Thing that keeps track of each new version.
Templates are also used to create new Things, which are clone copies.
Product
Based on a Template and contains a list of serial Numbers to facilitate provisioning.
COMPATIBLE HARDWARE
ARDUINO
Prototyping
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments.
See a usage example here
RASPBERRY PI
Prototyping
The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.
