OZW refresh automatisation script

[samuelAN]

Hello,

I have one FGT001 heat controller working on domoticz. I would like to poll the device when a temperature setpoint is sent to it (after some seconds).

(For those who are following the issue with the FGT001 is that OZW does not handle the way the FGT001 send back its new setpoint value... Consequencly, in order to have an up to date setpoint in Domoticz, is it necessary to enable polling of the device... which drains very fast the batteries)

The idea is to force polling after applying a new setpoint, and use a "classical" polling configuration with very large interval (i.e 1 hour) in order to avoid dead node.

With some search, I found a script called "RefreshZwave", but I have no idea if this kind of script would help and how to put it in place (I am not an expert with Domoticz...)

Can someone help me with that?

Thanks !!

The "RefreshZwave" script that I found is the following :

Code: Select all

#!/usr/bin/php
<?php
$domoticzurl='http://ip:port/';
file_get_contents($domoticzurl.'json.htm?type=openzwavenodes&idx=5'); //Change idx to idx of zwave hardware
RefreshZwave(10); //Updates zwave device with zwave ID 10. 

function RefreshZwave($node) {
	global $domoticzurl;
	$zwaveurl=$domoticzurl.'ozwcp/refreshpost.html';
	$zwavedata=array('fun'=>'racp','node'=>$node);
	$zwaveoptions = array('http'=>array('header'=>'Content-Type: application/x-www-form-urlencoded\r\n','method'=>'POST','content'=>http_build_query($zwavedata),),);
	$zwavecontext=stream_context_create($zwaveoptions);

Nobody can help me ?

This script will only work if a refresh command from ozwcp works.

Thanks Egregius , indeed the refresh command updates all information but .. not the setpoint value... so this will not work

No other idea to make a one time polling ?

I had exactly the same question and after a lot of googling and even checking the github-code I found a super-easy way to completely refresh a specific node that works for me.

httpS://IP:port/json.htm?type=command&param=requestzwavenodeinfo&idx=X
where IP:port is your domoticz installation and X is the Zwave-node-number + (it seems 16)
f.e.
IMy FGT has NodeID 010 (0x0a), so I invoke : http://Domo-IP:8080/json.htm?type=comma ... nfo&idx=26

I checked with a friend and it does NOT work with OZW 1.4 (but latest stable has OZW 1.6)

I haven't got a clue if the +16 is installation-dependant.
You can check the ID by going to 'hardware' in Domoticz, click OpenZwave USB 'Settings' . select a node in the page that follows and hover over 'Refresh Node info'. Bottom-left in your screen or in the status bar you'll see 'javascript:RefreshNode(Devicenumber)'

Hope this helps.

Keep in mind that this command will erase all personal settings of the node and restore it to factory defaults!
