I have a problem, I’ve been trying to find a way to back-up and restore a zwave.me chip with a replacement chip using the Z-Way C library API. I Basically want to be able to replace a faulty chip without having to go through the arduous process of re-pairing all of the things to the new zwave.me chip when it is replaced. I have tried to do this with the example Z-Way C library API code as I do not wish to install the zway User interface The steps I have run through to achieve this are as follows
1: check the things and the zwave.me chip are paired correctly if they are I run the script with the zwave.me chip I want to back up using the test_save(zway); method provided in the Z-Way C library example code. This creates a .tgz file in the /tmp folder called z-way-test.tgz
2: I turn off the Pi and replace it with a new z-wave.me chip
3:When the pi is restarted I recompile the C file to run first run the restore to factory settings method zway_controller_set_default(zway); I then run the restore method test_restore(zway); .
4: when I check the items not longer seem paired but when I put the zwave.me chip .but when put in the original zwave.me chip from which I took the backup everything the original zwave.me chip and items are still paired correctly.
So is there a way to back up a zwave.me and restore it without having to put all of the items associated with are zwave.me chip in discovery mode and re-pair them? if so how can this be done with the Z-Way C library API code?
Note: I am using openhab2 on my pi which I am always careful to turn off when I run the Z-Way C library API scripts
Backing-up and restoring a new zwave.me chip with the C API
Re: Backing-up and restoring a new zwave.me chip with the C
I’ve Analysed this problem in a bit more detail now. The save method works fine when you run test_save() it backs up the chips current state into and xml file and stores it in config.tgz .but when you take out the old chip and put in a new chip run and the test_resore method the changes are not persisting through to the newly inserted z-wave.me chip. The method zway_controller_config_restore(zway, data, length, TRUE); which should make it a full restore. The restore seems to run fine but when I do a test_save() again to see if the changes have persisted correctly the xml in the config.tgz file looks like the old configuration on the replacement chip not the newly restored configuration hence the changes seem not to have persisted. Also when I checked the pairing in openhab2 they are broken further indicating that the changes have not persisted
I put some snippets of the code and that I am using below. If anyone has any Ideas of where I’m going wrong it would be much appreciated
test_restore
Test_Save
Output when running restore "test_restore(zway);
