@Anduril said in set a time delay in java operation: Another minor question: I added Names to my sensors (which were auto-detected during node presentation if that matters), but they get overwritten with for example 74522 TSF:MSG:READ,17-17-0,s=22,c=0,t=23,pt=0,l=0,sg=1: which seems to be the complete serial incoming message for that sensor. Is this know and is there a way to avoid this name-changing? Yes, we have an option to lock the name. Add this property on your node. "lockNode": true For more detail have a look at https://github.com/mycontroller-org/mycontroller/issues/464

@anduril There is no direct option available to archive this setup. However, we have a workaround. Create a virtual node/sensor - Binary sensor (will give switch type) Add your virtual button(virtual sensor) to the dashboard Create an operation to execute a script Implement two rules that should trigger script operation when there is a change in the button If you want to control based on switch ON/OFF state, just read this switch state on your script.

@anduril I have removed the old method readXmlByXpath. Introduced XmlApi class to address xml stuff. mcApi.xml().read(uri, xpath) - Returns String uri - can be local disk path or http url xpath - should be a valid xpath mcApi.xml().readAsList(uri, xpath) - Returns List<Map<String, String>> uri - can be local disk path or http url xpath - should be a valid xpath mcApi.xml().update(uri, xpath, value) uri - should be local disk path xpath - should be a valid xpath value - String value will be replaced on xpath Is it also possible to update the values in the xml file? I don't mean adding new nodes or other fancy stuff, only updating for example /student/details/class from Three to Four. Yes, now it is possible with, mcApi.xml().update("/tmp/file-xml-demo.xml", "/student/details[1]/class", "Four"); As far as I read the xpath is just a pointer in the tree of an xml, so there is no option to manipulate items. Maybe there is another function available to do this. You can call readAsList, var list = mcApi.xml().readAsList("/tmp/file-xml-demo.xml", "//id[text()='4']/.."); // get first result var item = list.get(0); // get name, id, class item.get("name"); item.get("id"); item.get("class");

@anduril There is no direct options available. Let me have a look and update you

@Anduril You have to create UidTag for required variables, For example. If you want to show outside temperature, humidity and precipitation. Create UidTag for all these variables as follows, outside-temperature >> for outside temperature humidity >> for Humidity precipitation >> to show precipitation Note: Creat UidTag for the above value. Script: var myImports = new JavaImporter(java.io, java.lang, java.util, java.text); with(myImports) { var temperature= mcApi.uidTag().getByUid("outside-temperature").getResource(); var humidity= mcApi.uidTag().getByUid("humidity").getResource(); var precipitation= mcApi.uidTag().getByUid("precipitation").getResource(); } Now create an HTML template to show these values, <div>Outside temperature: ${temperature.value}°C</div> <div>Humidity: ${humidity.value}%</div> <div>${precipitation.value}mm precipitation during the last 24h</div> Use this script and template on dashboard custom widget.
