Alarm Clock

[ben999]

Guys

Funny discovery tonight :
"alarm time" value in PaperUI can be set by clicking on it !! It is not a read-only value, it can also BE SET !!!

Now the big question is: how can my node retreive that new value ?

21:17:04.816 [DEBUG] [rsAbstractConnection$MySensorsReader] - 50;255;3;0;21;0
21:17:20.291 [INFO ] [smarthome.event.ItemCommandEvent    ] - Item 'bedAlarm01' received command 21:12
21:17:20.296 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Node 50 found in gateway
21:17:20.298 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Child 0 found in node 50
21:17:20.299 [DEBUG] [rsAbstractConnection$MySensorsWriter] - Sending to MySensors: 50;0;1;0;47;21:12

Looks like gateway sends a text message (47) towards node... so sketch needs to make a difference between "lock" messages and "alarm time" messages, right ?

/*** receive alarme state and time from controller ***/
void receive(const MyMessage & message) {
  if (message.type == V_LOCK_STATUS) {
    setAlarmState(message.getBool(), false);
  }
  if (message.type == V_TEXT) {
    do (
         use strtok_r(message.data, ";", &p) to extract payload
         somehow extract hour and minute from that payload
         store them in int alarmHour int and alarmMin
  }
}

A clue to get me on the way ?

Thanks a lot for your input :)

Guys,

I need some help por favor :)

I am fighting against payload! The picture (a few posts above) shows that i can modify two values (seen under "Heure de réveil")

As i validate the new value, the gateway sends a message to the node

Sending to MySensors: 50;0;1;0;47;21:12

Which is great, that's a new feature to me :)

Now on the node side : I have included

void receive(const MyMessage & message) {
  if (message.type == V_TEXT)
    Serial.print(message.data);
   // or Serial.print(message.getString());  // works fine too
}

Serial monitor of node shows

21:12

Lovely jobly sounds good

I am now facing two major problems to me as a noob:

• what is the format of "message.data" ? string? whenever i try to play with it i get some "invalid conversion" from IDE...
• how to split that "message.data" into two integers (alarmHour and alarmMin) ?

Thanks for your help ! That should be the final shout for help as this project is nearly achieved...

[ben999]

Can someone please comment on this DIY mess (it's a mix of bits and pieces found here and there)

void receive(const MyMessage & message) {
  if (message.type == V_LOCK_STATUS)
    setAlarmState(message.getBool(), false);
  if (message.type == V_TEXT) {
    char *alarmTime =  message.data;
    char* token = strtok(alarmTime, ":");
    alarmHour = atoi(token);
    token= strtok(NULL, "");
    alarmMin = atoi(token);
  }

It works the way I need it but i guess it's a dirty way of getting there... your eyes might start bleeding :D i get this from compiler :

warning: invalid conversion from 'const char*' to 'char*' [-fpermissive]
     char *alarmTime =  message.data;

Any suggestion to make it neater?

@ben999 message.data is const char* which means its contents can not (or at least should not) be modified.
Then you set the alarmTime pointer to point to the same message.data, which means that if you modify the contents of alarmTime you will also modify the contents of message.data (they are not two copies of the same thing, they are the same thing)
The definition of strtok is

char *strtok(char *restrict source, const char *restrict delimiters);

which means the first parameter must allow modification (no const), while the second does not need modification.

The man page of strtok also says this (my emphasis):

The strtok function returns a pointer to the beginning of each subsequent token in the string, after replacing the separator character itself with a null character. When no more tokens remain, a null pointer is returned.

which explains why the parameter must allow modification.
That's why you can't do

const char *alarmTime =  message.data;

I am not a c expert, but I think you should do this instead:

void receive(const MyMessage & message) {
  if (message.type == V_LOCK_STATUS) setAlarmState(message.getBool(), false);
  if (message.type == V_TEXT) {
    char alarmTime[MAX_MESSAGE_LENGTH];
    strncpy(alarmTime, message.data, MAX_MESSAGE_LENGTH);
    char* token = strtok(alarmTime, ":");
    alarmHour = atoi(token);
    token = strtok(NULL, "");
    alarmMin = atoi(token);
  }
}

MAX_MESSAGE_LENGTH is provided by the MySensors library.

@mfalkvidd thank you very much for your detailed explanation !

It does make a lot of sense

And it compiles perfectly

Thanks again for taking the time to correct and explain :)

Nice project would love to see the finished product as I want to try it as well. Can you post all the details once you get it do Easy?

Thanks and good luck

Hi I need your help, I created this clock and complied the sketch, looked like it worked but when adding it to very I get the error message that D_LcdText1.xml is not available. Where do I find that and how do i add it to the Vera Plus?

Excellent project and can't wait to have it up and running.
