@mfalkvidd You are right but may be should there be for each sensor or actuator first the most basic sketch but also at the end of the page a complete version with all functionalities and granted to work by the mysensors team.

Of course for the complicated sketch version a big warning in red letters that this is not recommended for newbies would help...

[fhenryco]

After testing some functionalities of nodemanager, i was wondering if already somebody was working on making a GUI for nodemanager which would allow to build one's sketch completely from a graphical interface (at least the most common and basic functionalities) : i thing the great work that resulted in Nodemanager has so well structured the various functions needed that it has already paved the way for creating such a graphical interface.

There was a user some time ago that was trying to make a web GUI

I would agree that more advanced sketches 'should' be included on the same page. Keep all the info in one resource place. Provided it is clearly marked as an advanced project it might help people looking for similar functionality or just interested in learning more about programming....

wow! fantastic! ... the github link readme warns that it's not yet fully ready but the interface is already impressive!
I still have the same question i had for nodemanager though : for measuring another battery than the one that feeds Vcc obviously another pin is needed, however why not propose as well the option of measuring such pin voltage but with Vcc as the reference rather than the internal 1.1V which most of the time makes necessary a voltage divider ? Actually i did the modification in nodemanager.cpp to use DEFAULT (~3.3V) rather than INTERNAL (1.1V) reference for a 3.3 pro mini and i can get the expected battery level without any voltage divider.

Another unrelated question i have is : could there be any way to adapt the idea of the readVcc method (which is to measure the internal 1.1V against the Vcc reference to get Vcc) but using any voltage applied to a pin as the reference to again measure the internal 1.1 against it ? This would allow the masurement of any voltage greater than 1.1 without voltage divider while the usual method would be applied for measuring any voltage lower than 1.1 ... what did i miss that makes this impossible ?

[gohan]

We need to use the internal reference since it is the only stable voltage source and you need the voltage divider to lower the measured voltage between 0 and 1.1v. There are not many options to choose from

[fhenryco]

i also just realized that there is a special AREF pin intended for what i was thinking about ... but it's not available on the mini pro.

My measurements using Vcc as Ref have been indeed very fluctuating, however what i get was highly sufficient to monitor the battery feeding a 3.3v step up regulator to the arduino and help anticipate failure

[skywatch]

I just noticed another thing that should be changed in the 'relay with button' sketch....

S_LIGHT should be S_BINARY
V_LIGHT shoud be V_STATUS

[APL2017]

I would like to clarify operation of the sketch, where more than 1 sensors input are used along with more than 1 relay actuator. in one node

1. Does node need unique child ID for each sensor input AND relay output?
2. If that is the case how child ID is assigned to relay actuators in the above examples?

[jopebe]

This is a nice sketch and it is very universal for relays. Now m looking for a similar sketch for digital inputs such as buttons i.e.. I would like to join both. The problem: I want to use a mega for reading status of a lot of digital outputs (min.20) of another ISP. It is only High or Low. Only when the level changes, I want the mega send a message to the gateway. I tried this "for" loop, but it didnt help. There are too many informations sent to the gateway. I imagine a solution, where only a change at the pin will create an information, that is sent to the gateway.
Here my test, which didnt run:
void loop()
{

for (int sensor=16, pin=BIN_1; sensor<=NUMBER_OF_BIN; sensor++, pin++)
{
int BUTT;
int BUTTOLD;
BUTT =digitalRead(pin);
if (BUTT != BUTTOLD && BUTT !=0){
MyMessage msg(sensor, V_TRIPPED);
send(msg.set(BUTT ? "1" : "0"));
}
BUTTOLD = BUTT;
wait (900);
}
}
Has anybody an idea or a hint for me?

[gohan]

I believe there is a logic error in the sketch as you would need to declare global variables BUTTOLD_XX unique for each button, otherwise how can you keep track of the variable between each loop and FOR iteraction?

[jopebe]

Thank You for Your quick answer.
Do I understand You correctly: I must index the BUTTOLD?
As BUTTOLD[pin) for example or how? Where?

[gohan]

You need to create the single variables one by one, unless somebody else has a better way to do it

why i can't compile for arduino pro mini on other boards i can upload

[mfalkvidd]

@mitja-blazinsek the error messages are usually essential to figuring out. Did you get any?

OK it's probaly because ia have mini with 168 chip i have to buys 328 :( again wait 1month to arive from china

[lekeb]

hello.
I am building a node with several kind of sensors and two relays.
My sensors use CHILD ID from 0 to 3. I would like to start child ID of relay from 4.
How I can't do that with this sketch?
I guess I have to change this part of sketch :
"for (int sensor=1, pin=RELAY_PIN; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
// Register all sensors to gw (they will be created as child devices)
present(sensor, S_BINARY);"

correct?

thanks

[rejoe2]

@lekeb
You may do something like this:
In Header:

uint8_t DS_First_Child_ID = 7; //First Child-ID to be used by Dallas Bus

an then in presentation():

for (int i = 0; i < numSensors && i < MAX_ATTACHED_DS18B20; i++) {
    present(i + DS_First_Child_ID, S_TEMP);
}

But afaik, it's not recommended to shift the ChildID's for relays but always start with 1. Imo it's better to change the ChildID's of the other attached sensors. You may also take care (in case of shifting ID's) about a consistent mapping from ID to the PINs where the relays are attached.
