Greenhouse controller

[azlan]

What if I can not use any controllers out there, is there any sample code on controller site, like how do controller communicate to sensor wirelessly, is there example code to retrieve/send data/command from/to sensor/actuator?

Well, the api documentation should give a good hint howto communicate with the MySensors network.
I think most of the controllers/controller-plugins are based on the this documentations.

You should look at the available controllers if there isn't a controller that fits your need.
Maybe, if you outline your needs, someone can you point in the right direction.

Where is the documentation?

Especially the serial api gives a good hint how a controller should handle messages.

@Oitzu I have another question. If I decide to use gateway as controller, How do I pull data to use in my controller code in gateway instead of forwarding to Raspberry PI. Can you help me with a simple code showing how it can be done?

[Oitzu]

@azlan you mean using the gateway itself to control the nodes?
Never done that.
This would mean you wouldn't use a gateway at all.

Normally the gateway represents a point in the mysensors network a controller is connected to.

What do you acutally want to do? Maybe we can answer better with a picture of the whole situation.

Hint: A mySensors network without an gateway would need something like an "master-node". A node with id 0 that assigns new node ids and control the other nodes.
But the functionallity of this master node would be very limited due to ressource limitations.

@Oitzu Well, What I want to do is; Make gateway my controller ( intend to use arduino yun), the reason for that is none of the controllers fit my need, which is I want to automate hydroponic greenhouse and it is something like this ; https://www.youtube.com/watch?v=-IfvbrZJ4sY
I want to ask again " How do I pull data to use in my controller code in gateway instead of forwarding to Raspberry PI. Can you help me with a simple code showing how it can be done?".
