Repeater and blinking leds [SOLVED]

[rvendrame]

@HarryDutch, I don't see anything wrong with your receiver sketch. Two suggestions:

• Are you able to use the serial-monitor at the receiver node, and confirm if any message is arriving there?

• If you move the code from IncomingMessage() to loop(), does the LED turn on/off? ( just for the sake ... )

[HarryDutch]

Moved code from IncomingMessage() to loop() and the led is on for 2 seconds. So the led is working as it should.

Did changed things a little bit . Node 2 (temperature/humidity sensor in the fridge) is sending temperature/humidity to controller and temperature to node 3 (the node with the leds).

gw.send(msgTemp.set(temperature,1));
gw.send(msgHum.set(humidity, 0));
gw.send(msgTemp.setDestination(3).set(temperature,1));//SEND TEMPERATURE ALSO TO NODE 3

This is the output serial monitor node 2:

sensor started, id 2
send: 2-2-3-0 s=255,c=0,t=17,pt=0,l=5,st=ok:1.4.1
send: 2-2-3-0 s=255,c=3,t=6,pt=1,l=1,st=ok:3
send: 2-2-3-0 s=255,c=3,t=11,pt=0,l=15,st=ok:Pressure Sensor
send: 2-2-3-0 s=255,c=3,t=12,pt=0,l=3,st=ok:1.0
send: 2-2-3-0 s=0,c=0,t=7,pt=0,l=5,st=ok:1.4.1
send: 2-2-3-0 s=1,c=0,t=6,pt=0,l=5,st=ok:1.4.1
Temperature = 17.10Humidity = 57.90send: 2-2-3-0 s=1,c=1,t=0,pt=7,l=5,st=fail:17.1
send: 2-2-3-0 s=0,c=1,t=1,pt=7,l=5,st=ok:58
send: 2-2-3-3 s=1,c=1,t=0,pt=7,l=5,st=ok:17.1

Looking at the last line it seems to me that sending the temperature value to node 3 is ok.

Node 3 (also a repeater) has now a copy of the Relay Actuator sketch where I have changes relays into leds. There are 3 leds that I can now switch on and off by using the controller. This is working. This is the code for the function IncomingMessage():

**void incomingMessage(const MyMessage &message) {
if (message.type==V_LIGHT) {
digitalWrite(message.sensor-1+LED_1, message.getBool()?LED_ON:LED_OFF);
gw.saveState(message.sensor, message.getBool());
}
// ==== THIS IS NOT WORKING ==========================
if (message.type==V_TEMP) {
digitalWrite(6, HIGH);
delay(2000);
digitalWrite(6, LOW);
}
**

And this the output of the serial monitor of node 3:

**repeater started, id 3
send: 3-3-0-0 s=255,c=0,t=18,pt=0,l=5,st=ok:1.4.1

Well...

• Try put some delay() between sending each message (or leave just a single message to node 3).

• The relay sketch also acts like a repeater, maybe it is trying to send the message to 'node 3' to GW instead? Try to disable the repeater function:

     gw.begin(incomingMessage, AUTO, false );

@rvendrame

Really appriciate your assistance. All this MySensors stuff is working perfectly well, so not getting this node to node communication right is driving me nuts!

First thing tomorrow I will try your suggestions. Thanks again.

[Chaotic]

I'm interested in the concept of node to node messages but for your use case couldn't you just have the gateway send the message to toggle the LEDs once the message gets there?

So
Node inside fridge -> Relay -> Gateway -> LED Node

rather than

Node inside fridge -> LED Node
Node inside fridge -> Relay -> Gateway

which is what it seems like you are attempting to do.

Also I had not thought of putting a node in a fridge before but I'll be looking into that now.

[rvendrame]

@Chaotic , I was about to suggest the same to @HarryDutch , however it seems he wants to take the GW out of the equation (for some reason that we don't know).

By putting the GW in the middle it should work perfectly well, I do agree with you.

[HarryDutch]

@rvendrame and Chaotic

You're both right of course. I'm now using the automation function in EasyIoT and that's working. So Node inside fridge -> Relay -> Gateway -> LED Node. On the other hand: node to node communication should be possible so I will do some more testing to see if I can get it to work. Thanks for now.

[Chaotic]

@HarryDutch

I wasn't saying don't look at the problem. I think Node to Node communication should work.

It just this comic

comes to mind

At a certain point you have to realize you are solving the problem out of principle (which is a valid reason) rather than to solve the problem.

[HarryDutch]

@Chaotic

Hahaha. I've printed your comic. It's hanging now in front of me to remind me that there are different ways to solve a problem. By using the GW I now have a perfectly working project. Thanks for pointing me into the right direction. But I will still try to get the node to node communication working although it's no longer a problem!

@HarryDutch The comic is actually from XKCD if you click the image it should take you to the actual site.
