Hi everyone !

For my studies, I choose to create a "home monitoring" project. My project need to request a many informations like temperature, .. via a gateway using mysensor API. My controller need to be on Windows IoT (C#) and I need to write all the informations in database. So, everything is good except one thing.

After searching a looooong time i'm blocked !

I want to create my own controler working on Rpi with IoT (C#) but I don't know how send message to my gateway in serial USB. I found nothing about how to send request.

I want to know how send request from my controller to my gateway. I can use an external API to do that, but I don't know what ><

Please, someone can help me?

Thank you

PS : Sorry if my english is too bad, I'm a french guy !

@sundberg84 It's work ! Thank you

I try 2 power supplies, and I put the radio far away from it.

And I use a decoupling capacitor like says in "Connecting the radio" page

I don't understand what happend wrong with the log, can you explain me? Thank's

Oh, when I plug a nano on computer with USB the GW connect without problem

Hi everyone

I've build a relay to control my Senseo. All seems ok, I power the arduino/relay with a 5V transfo from USB charger, all seems ok, my arduino was add by the GW, but i can't send order to it.

See below my log

Thanks for your help, and happy new year

@gohan ok

I understand for the controller, but I think I miss something about the ID_RESPONSE

Imagine this situation:

I have just one sensor with no ID
The GW send me (the controller) : '255;255;3;0;3;' // Sensor want a node_ID
If I want to give it the ID 1, what I need to send to the gw? I think something like '255;255;3;0;4;1', that's right?

EDIT : I try and it's work now, but I need to clear EEPROM first

Hi everyone !

Let's do a check up :

• Read from a GW in serial connection : ok
• Read information when I give a static ID : ok
• Find a node who want an ID : ok
• Give an ID to a node with my controller : nope

So, the question is, if I receive '255;255;3;0;3;' my controller understand it's an ID_REQUEST and I need to use an ID_RESPONSE, but if I want to give an ID I need to build something like this :

node-id ; child-sensor-id ; command ; ack ; type ; payload

node-id : ??
child-id : ??
command : 3 for internal
ack : 0 ?
type : 4 for response
payload : new ID (ex: 101)

What are the node-id & child-id if the sensor doesn't have one?

One more time, I want to thank's all of you, with your help it's more easier to understand and I start to see the end !

EDIT : One more thing, I have an idea. I want to open a pop-up when a new sensor is on to choose for wich room is it.
Can I give an temporary ID (like 254), wait for a first message with ID 254, with a first message I can see what type of sensor is, open a pop up, and give a new ID after I choose the room?

Hi ! Thank's for working
I add the libraries in "MySensors external examples" to Arduino IDE but when I want to compile I have this one log error :

DhtTemperatureAndHumiditySensor.ino:43:25: fatal error: MySensors.h: No such file or directory
compilation terminated.

In MySensors folder's libraries, I have a MySensor.h, without 's' . This is one? Do I forget something?

Thanks

@sundberg84 It's work ! Thank you

Ok, if I right, there is a trouble with a motionsensor who want an ID ?

Do I need to give it one, or it's done by a gateway?

Hy everyone ! So, THIS IS WORKING ! Thanks a lot

Now, new problemes ! (It's not funny without)

I build a serial gateway and a motionsensor

This is my log

image url)

0;0;3;0;9 -> ok it's a gateway init
0;0;3;0;14 -> gateway is ready

but, what is the next one? Normally I will receive just x;x;x;x;x; right? what's about read: 255-255....

Thank you
