gateway serial and dimmer example

MCF

hi, i'm trying to add the led dimmer example on my gateway sketch, but i don't realy know how? can someone show me the way?

MCF

this is the code i use :

/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*******************************
*
* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on seral which will be sent out on radio network.
*
* The GW code is designed for Arduino Nano 328p / 16MHz
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
* - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or recieve crc error
*

it seems to work, but sometimes the led turns off without any reason....

@MCF my guess is that the gateway receives a message for another sensor. This triggers the receive function.

Try printing message.sensor inside the receive function to verify that this is the case.

The solution would be to check that message.sensor == getNodeId() and only handle the incoming message when that is true.

MCF

@mfalkvidd you mean something like```
void receive(const MyMessage &message)
{
if message.sensor==getNodeId(0){ //the node id of my passerelle
if (message.type == V_LIGHT || message.type == V_DIMMER) {

//  Retrieve the power or dim level from the incoming request message

mfalkvidd

@MCF exactly

MCF

if i write getNodeId(0), there is too many arguments. so i tryied just getNodeId().
this doesn't work, and i think i know why: message.sensor is a child ID isn't it?

mfalkvidd

@MCF yes, you're correct. It should be message.destination, not message.sensor. Sorry about that.

If you have multiple leds and want to control them individually you can use message.sensor though.

MCF

@mfalkvidd thank you very much, i was searching in vain a list of the mymessage class!!!! do you know where can i find that ?

MCF

so i wrote

if (message.destination==0){

and the light still doesn't work. every destination message on the network is the gateaway, right? so how can i just dim the led attached on her ? maybe i dont need to send a message?? I'm a litle bit confuzed

mfalkvidd

@MCF the message.destination link in my last post shows the .h file where the message variables are defined.

Maybe print all of them and see if there is anything that differs between "real" and "false" messages?

message.getCommand() might be useful as well.

hi, i'm still trying to understand how to drive my gateway led strip! maybe i miss to tell you that i wanted to dimm that only with my controler, which is a domoticz on a rpy. is it the same way as usual, or is there another way that sending message to the gateway because i can't understand how to do!

MCF

@mfalkvidd hello, i'm sorry to say that, but i don't know how to do.. i try to understand how mysensors work but i really need your help!

Plantex

Hi @MCF

I've just started a topic with two sketches for LED Dimmer. Have a look and test one of two sketches. 1st one is based on Yours with a little change to save the last dimmer status after on/off. 2nd is basing on Dimmable Light sketch (using EPROM to save the status).
Good Luck !

MCF

@plantex hi, my problem is to dimm led on the gateway sketch, because i need to sort messages. i can't find exemples on the forum, it would be very strange than no one did that already!

towme

@MCF

Maybe it is not a problem of the code (because that looks ok), but with the wiring, or too little power to the led stripe.
How long is your LED stripe?
Also a mistake I have made, when I set up mine, was that every mosfet you use in your setup needs to be attached to a separate cooler / heat sink, because the back of the mosfet is a middle pin also.
Another thing is I see in your code that you present your dimmer as child id 1, then you should use 1 and not 0 in your debug messages.
Plug your arduino to your computer and open Serial monitor in the arduino ide while testing your setup.

(Also do not confuse analog and digital pins on the arduino, both can be number 3 ) ;)

cheers

@mcf
One more thing.
Probably this is obvious for lots of forum users but sometimes I had some problems with some sketches when uploaded to gateway-arduino (connected to Domoticz) and debugger was enabled.

Try to comment out #define MY_DEBUG see if there is any change.

From other side do You need that sketch on gateway ? maybe transfer it to node with nrf24 ?

MCF

@plantex just because it's too bad not using those outputs! but you're right, i think i 'll solder one mini pro, and that question will be over!!

MCF

@towme hi, this is not a hardware problem, my led stripe is two meter long, and i've checked the mofset with another sketch. The problem for the debug message is that i don't know how to open serial monitor on the gateway connected to the rpy (i use an arduino uno ), so it's hard to check debug message live
