Making IoT visual. Using Node-RED for hybrislabs moto.

Our prototype ‘moto’ is just taking an interesting turn. It’s technically pretty robust, we’re finishing off some UI/product choice things and we asked ourselves: that’s it? While we’ve developed one story for each prototype so far, it seems we’re focusing on different, higher-level issues when it comes to IoT with moto. That’s the issue of how things are wired up, how things can interact and how existing configurations can quickly be changed.

So instead of one story, we’ll have many stories for moto. It will stay interesting, from a technical perspective, too. But the real story is: using Node-RED extensions, we’re able to rewire the logic of moto very quickly. And: it’s a tool for business-users. No hardwired setup.

Just like most other IoT-focused prototypes that we have (Wine Shelf, Funky Retail, Tiles), Moto also has a REST-based web API to control the light and motion. As well as a webhooks-based system to communicate with the outer world. But because moto is also built around MQTT (just like funky retail), it is easy to extend. With Node-RED and MQTT, we have a direct hook into the core messaging system of our IoT prototype. And we’re using the extensions we’re currently working on to make the commands and events easy to wire up. Take a look at a very simple example:

Here, a node triggers every 5 seconds. It will first hit the ‘red, slow, counter-clockwise’ node and the connected moto (here #2) will begin to turn red and slowly rotate counter-clockwise. After a delay of 2sec, it will turn green, move clockwise and fast. And finally after another 1 sec delay it turns off the motor and the LEDs turn white. It then starts over again.

We’re just having the first successes with Node-RED, but it looks very promising to become the brain of our prototypes. It might be smart move, as others (e.g. non-technical people, the business guys, the guys with the smart stories) can rewire moto in whatever flavor they want.

Next up in tech are the input nodes, e.g. moto can send presence events that can start interactions.

Just to wrap up, another example where we took the current temperature in Munich, converted that into a moto command and send it to moto for displaying the temperature via light:
