Experiences with openHAB?

knebb2

Hi all,

I am looking for a control unit for my upcoming smart hone.As I already have a M103 running for my heating (coded it on my own based on C) I prefer to use it for the control unit for smart home.

I was thinking of using openHAB as it appears to be the most active and stable way for such a unit (tried with NodeRed but this looks really complicated for me) Some years ago I did some first steps in FHEM - I could imagine to get it running...

Anyway, anyone here who has some experience with openHAB on a Neuron device?

Thanks!

Hi,

just for reference and to help future questions:

I am running OpenHAB on a dedicated RasPi. It is a Java application which I do not want to run on a Neuron. Keep it simple and stupid.

In C code it was not too complicated to get data from OpenHAB though curl calls.
See code snipplet:

/* Function gets calledd with an item name          */
/* The url is defined here globally:                */
/* url="http://openhab.domain.com:8080/rest/items/" */

long get_2file(char *url, char *filename )

{
CURL *curl_handle;
FILE *FI;

int r,code;

code = 0;
curl_handle = curl_easy_init();

/* set URL to get here */
curl_easy_setopt(curl_handle, CURLOPT_URL, url);

/* disable progress meter, set to 0L to enable and disable debug output */
curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 1L);

/* use default write function */
curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION, NULL);

/* open the file */
FI = fopen(filename, "w");
if(FI) {

        /* write the page body to this file handle */
        curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, FI);

        /* get it! */
        r = curl_easy_perform(curl_handle);
        if (r != 0) {
                code=-1;
        } else {
                /* Data is now in the file */
        }
        /* close the header file */
        r = fclose(FI);
} else {
        code=-1;
}
/* cleanup curl stuff */
curl_easy_cleanup(curl_handle);

return code;
}
