ZWay: notification on event

Having now my sensors now installed "properly" (well, the sensors are hell to mount on PVC) on the door and windows at home, it is time to set-up my little ZWay application to get notified when these sensors are generating some events. More precisely, when a window or door gets open...

The ZWay API provides the possibility to install some callbacks when "data holder" are changed. Therefore the first thing to investigate is the data holder.
There are a few functions to get a hand on a data holder:

  • zway_find_data(...)

That one requires a data holder as argument, so that's not the one we need.

  • zway_find_controller_data
  • zway_find_device_data
  • zway_find_device_instance_data
  • zway_find_device_instance_cc_data
These are the functions to use; to get the "root" of the data holder, you can simply provide an empty string as parameter e.g.

ZDataHolder dataHolder = zway_find_device_instance_cc_data(theZWay, 2, 0, 48, "");
Given a bit of code to display a data holder in the callback, this will display the following when my sensor ID=2 instance=0 commandClass=48 (sensor binary) will be changed:
Data change type 129
version=1
security=False
interviewDone=True
interviewCounter=9
level=True
Data change type 129
version=1
security=False
interviewDone=True
interviewCounter=9
level=False

ZWay: getting the device list.

Back after a while... and a son! Here is a piece of code that can be used with the latest version of the ZWay library. It makes it possible to retrieve the Z-Wave device list and display the device names and associated XML file (each recognized device can be associated to an XML that contains a bunch of meta-data: name, description etc.). int main(int argc, char ** argv) { ZWay theZWay; ZWError result; memset(&theZWay, 0, sizeof(theZWay)); result = zway_init(&theZWay, "/dev/ttyAMA0", "/home/pi/src/razberry-proxy/config", "/home/pi/src/razberry-proxy/translations", "/home/pi/src/razberry-proxy/ZDDX", stdout, Warning); if (result == NoError) { result = zway_start(theZWay, &terminationCb); if (result == NoError) { printf("Discovering...\n"); result = zway_discover(theZW...

First steps with the ZWay library

The Z-Wave "RaZberry" installation comes with everything needed to be able to do some custom development in C; everything is installed in the /opt/z-way-server  directory. There, one can find: A set of (documented, nice!) C header files found in /opt/z-way-server/libzway-dev : CommandClassesPublic.h FunctionClassesPublic.h ZDataPublic.h ZDefsPublic.h ZErrors.h ZPlatform.h ZWayLib.h A set of libraries found in /opt/z-way-server/libs : libmicrohttpd.so libv8.so libzwayhttp.so libzwayjs.so libzway.so For the ZWay stack to run properly, it is needed to provide the necessary configuration files. Instead of using these directly from the installation folder, I made a copy in order not to mess up too much with my working/configured setup. The following directories from the ZWay installation folder are needed: config translations ZDDX For experimenting I made a small Makefile in order to build and run. main.out: main.c gcc -I/opt/z-way-server/li...

Libcurl: perform a REST HTTP PUT

The libcurl library does not provide a clear example on how to issue HTTP PUT operations in a REST context; the examples are mainly about file transfers . For my proxy application this is not really what I need: I want to perform a REST HTTP PUT, keep it simple, meaning without using the "Expect" and "Transfer-Encoding" that libcurl adds by default. After some struggling I discovered that this behavior can be changed by using the following code: CURL * pCurl; struct curl_slist *headers = NULL; headers = curl_slist_append(headers, "Content-Type: application/json "); headers = curl_slist_append(headers, "Content-Length: 12345 "); headers = curl_slist_append(headers, "Expect:"); headers = curl_slist_append(headers, "Transfer-Encoding:"); pCurl = curl_easy_init(); curl_easy_setopt(pCurl, CURLOPT_VERBOSE, 1); curl_easy_setopt(pCurl, CURLOPT_PUT, 1); curl_easy_setopt(pCurl, CURLOPT_URL, " https://your-server.app...
