This thread contains comments for the article "MySensors @Eindhoven Maker Fair 2-3 September" posted on MySensors.org.

I have mailed the person responsible for the integration. Hope to get some answers tomorrow.

Ok, updated doc. @Yveaux, feel free to update the text I wrote.

If you use the MY_RX_MESSAGE_BUFFER_FEATURE, you must connect the IRQ pin. Otherwise it's not needed.

I'll update the documentation.

@R2DK, sounds strange.

Should just be a one-click operation to order... and you shouldn't have to do any gerber uploads.
Could you PM me who you were in contact with over at ITEAD?

Sorry, no. Realised modern phones BT goes into sleep mode which means they don't announce themselves for longer periods. Kind of made it meaningless for the application.

@eframe said in SmartThings plugin:

Communication is: Controller to/from Gateway to/from Sensors.

All communication between the controller and sensors goes through the gateway.

Not nessesarily. But when a sensor is joining the wireless network it communicates with the gateway (per se the controller). To fetch a unique id and present itself.

Can the senors communicate with each other through the gateway and not go through the controller?

Yes, this is also possible. If a node addresses some other node, the gateway/controller won't see this communication. But normally a sensor sends its data to the gateway/controller to have the home automation controller log or react on it.

Just trying to get my head straight on the communication path. If I'm using a controller like SmartThings where does MySensors get installed? On the gateway?

The MySensors library is installed on the gateway and all the nodes. When creating the gateway you can choose to have it communicating via serial line or ethernet if your ardiono has a ethernet controller. See build pages for more examples of gateway types.

SmartThings provides a set of REST api's for the integration. Does the gateway handle REST api calls?

No not directly. You would probably have to create some integration software which transforms the incoming data to rest-calls. But how would you solve outgoing data (I.e. if you want to control a relay from the SmartThings controller)?. Does SmartThings allow outgoing rest-calls to a service of choice?

The best thing would be if SmartThings had some real plugin architecture... Most controllers allow running Lua scripts or some other way of writing native plugins running on the controller itself. Really unfortunate if they lock down the box from an integration perspective. That's why I usually prefer to run open source software myself [rant warning ].

Yes, you would have to write a SmartThings plugin which talks to a MySensors gateway either over a serial or ethernet connection. The protocol is simple and described here.

The example "controller" I posted above is an example of how to talk to the gateway.

I have no idea if SmartThings allows you to create/install plugins. But you need to place the code somewhere that keeps the connection to the gateway open and interprets the MySensors messages.

Hi and welcome @eframe,

There's a really simplistic controller implementation available on github that you can have a look at here:

https://github.com/mysensors/MySensorsSampleController

Also, most of the supported controllers is open source projects and their respective plugin is available as open source.

Let us know if you need more pointers to get started.
