💬 NodeManager

[Dencan]

@user2684 It appears that this problem is caused by a bug in bootloaders used in some Arduino boards.

The solution suggested is to flash optiboot bootloader to the Arduino Pro Mini. Or not using a bootloader.

I use mostly barebone atmega328's with optiboot bootloader, working perfectly with reboot function, so I haven't been aware of the problem until now when I used a pro mini.

Please read this article which explains the cause of the problem and suggested fix.

I will try it on a pro mini when I have time.

@Dencan thanks, very good information. Based on what you are saying, I'd probably re-introduce the reboot pin as a backup solution just in case somebody doesn't want or can move away from the default bootloader. In this way both the approaches will be available. Thanks!

I have a hard time figuring out one simple thing... Is the NodeManager code supposed to be on the sensors? Or is it supposed to be on the Gateway? Or both??

[Sergio Rius]

@ronnyandre With NodeManager you can build sensors but also configure a gateway. :+1:

[ronnyandre]

@Sergio-Rius I think I understood it correctly. Code goes on the sensors, not on the gateway itself? That means, the MySensors Serial Gateway I use is only a carrier of the messages that NodeManager receives on the sensors I implement the code?

@user2684 Hi, i am trying to get started with NodeManager, and I have a question about dht configuration?
I would like to set it to not update values if temperature is not changed, something like ((SensorLatchingRelay*)nodeManager.getSensor(1))->setTackLastValue(true);
But how do I select both sensors, are they numbers 1 and 2 (both temp and humidity)?
I would also like to add these settings to them.
((SensorLatchingRelay*)nodeManager.getSensor(1))->setForceUpdate(4);
((SensorLatchingRelay*)nodeManager.getSensor(1))->setFloatPrecision(1);

Thanks!

[Sergio Rius]

@ronnyandre NodeManager is a code wrapper. It's a collection of libraries, that has been join with a configuration script that automatically picks and does what is needed for your like.
You can make a common temperature sensor, but if you look at the documentation and the NodeManager.h code or the ino template itself, you have options for gateway configuration.
So you should be able to configure a gateway sketch and burn into your hardware.

I hope this gives some light before the dinner ;)

@dakipro said in 💬 NodeManager:

((SensorLatchingRelay*)nodeManager.getSensor(1))->setForceUpdate(4);
((SensorLatchingRelay*)nodeManager.getSensor(1))->setFloatPrecision(1);

SensorLatchingRelay is wrong here.
Try:

  int sensorDHT_Id = nodeManager.registerSensor(SENSOR_DHT22, PIN_DHT);
  SensorDHT* sensorDHT = (SensorDHT*)nodeManager.getSensor(sensorDHT_Id);
  sensorDHT->setSamples(5);
  sensorDHT->setSamplesInterval(2001);
  sensorDHT->setTackLastValue(true);
  sensorDHT->setForceUpdate(3);

Those options refer to the whole device, should be applied also to humidity. There was a bug on this but I think it was already corrected. If not, try with development version.

Thanks, right after posting the question, I have found a example on the topic itself (search function on the forum does not search current topic anymore, I had to scroll down to be able to "find in page").
I am now using this
int sensorDHT_Id = nodeManager.registerSensor(SENSOR_DHT22,4);
SensorDHT* sensorDHT = (SensorDHT*)nodeManager.getSensor(sensorDHT_Id);

Will see how it goes :)

[ronnyandre]

@Sergio-Rius Thanks man! I will definitely take a closer look. I just one silly last question....

Trying to use a simple DS18B20 temperature sensor, and I get the following error:

error: 'SENSOR_DS18B20' was not declared in this scope
nodeManager.registerSensor(SENSOR_DS18B20,3);

Seems like it doesn't like me declaring it. I have installed Dallas Temperature and One Wire through Arduino libraries.

[mickecarlsson]

@ronnyandre you need to uninstall those libraries and install those mentioned in the heading: Installing the dependencies: NodeManager

[ronnyandre]

@mickecarlsson Thanks, I will try that later today :smiley:

[user2684]

@Sergio-Rius @ronnyandre just to add something on top of what already discussed regarding the gateway thing, yes you can use NodeManager for the gateway as well or alternatively a standard gateway sketch, those are fully compatibile since NodeManager adds very little when running as a gateway, it just relies on the standard MySensors library and directives

[user2684]

@dakipro in addition to what @Sergio-Rius already pointed out correctly, consider when multiple child IDs are created, you would need to call those functions on EACH id. Have a look at https://github.com/mysensors/NodeManager/issues/176 for more details. Thanks

[user2684]

@ronnyandre ensure MODULE_DS18B20 is enabled in your config.h otherwise SENSOR_DS18B20 will not be made available. Thanks

[Sergio Rius]

@user2684 on #176 issue... and the sample I pasted before... then we have to configure Samples, SamplesInterval, TackLastValue and ForceUpdate for Temp and Hum separately?
It doesn't make sense to me.

[user2684]

@Sergio-Rius yes, this is the case, since two different and completely independent child IDs are created, you need to call the methods on both. This is true for any sensor creating multiple IDs. And you're right, it doesn't make sense to me either, it is something I've realized recently. I'm tracking it down with https://github.com/mysensors/NodeManager/issues/198 but I do not expect this to be an easy fix. Thanks

Hi, what's your calendar for v 1.6.0. I was looking forward to IO-Expander MCP23017 and TTP226/9 support in this release...

[user2684]

@vikasjee this was the plan, you're right, but I had to postpone a good number of requests supposed to be part of v1.6 since I wanted to allow this https://forum.mysensors.org/topic/6980/browser-based-firmware-generator which is dependent on NodeManager to come to life asap. So unfortunately I had to move those enhancement requiring some effort to v1.7 even if I already acquired the hardware. Sorry for that

[vikasjee]

@user2684 No issues! When are you planning for 1.7.0? Looking forward to an early release especially the IO-Expander MCP23017 support...
