Hi, I am new to OpenHAB and started to work with version 3. I struggle with a few things and unfortunately I am a bit confused on which instructions still work for OH3 and which don’t. I’ll post separate questions for each of my problems. This question is about the Thing Status . Problem / Goal: W…

[image] ringbuchblock: Therefore, I want to see at first glance when taking a look at an arbitrary item whether the underlying thing is still working correctly or not. Here’s the problem. Which underlying Thing? It is not unusual to have multiple Channels from multiple Things linked to the sa…

I am also interested in thing status and tried multiple code examples but all failed at least in ECMA. In OH2.5 and 3 DSL rules you could get for instance the thing/binding status by using var thingStatusInfo = getThingStatusInfo("mqtt:broker:mosquitto") and it shows you if i.e. the mqtt binding is…

[image] rlkoshak: Here’s the problem. Which underlying Thing? It is not unusual to have multiple Channels from multiple Things linked to the same Item. Right now I have only exactly one thing (sometimes several channels) linked to an item. However, I’d be interested in an example where it wo…

[image] chrismast: Due to a friend found this code that worked to get thing status (example mqtt): var Things = Java.type(“org.openhab.core.model.script.actions.Things”); var status = Things.getThingStatusInfo(“mqtt:broker:mosquitto”); How to you execute this? I tried with ECMAScript and…

My example rule below: var telegramAction = actions.get("telegram","telegram:telegramBot:telegram"); var Things = Java.type("org.openhab.core.model.script.actions.Things"); var status = Things.getThingStatusInfo("networkupstools:ups:ups"); //Actions if (status == "ONLINE") { telegramAction.send…

[image] ringbuchblock: However, I’d be interested in an example where it would make sense to e.g. link several things to a single item. Look at the Follow Profile Items | openHAB for one example. [image] ringbuchblock: I am currently solely working with Shelly devices and the thing’s sta…

It seems there is a way: [image] Monitoring Thing Status Bindings You can achieve that by being creative with the next-gen rule engine (NGRE) and the core.GenericEventTrigger module type and listen to a certain type of event, here ThingStatusInfoChangedEvent. …

[image] rlkoshak: So why not just use the Network binding to ping it and if it goes offline you’ll have a nice switch to tell you that it’s offline. If you are using MQTT integration, you could subscribe to the LWT topic and let the MQTT broker tell you when the devices go offline. You could al…

[image] ringbuchblock: In my case the thing is equal to the actual device. That’s frequently not the case. [image] ringbuchblock: Could you maybe point me to some examples or more information on that? I’ve only a Python version. https://github.com/rkoshak/openhab-rules-tools/tree/mai…

Hey together, it is possible to operate on Things if you really want to do that. You need a way to get a reference of ThingRegistry or ItemChannelLinkRegistry. Since the implementation of ThingRegistry is internal you can’t create your own. But both implementations are Services inside the framework…

That’s frequently not the case.

I’ve only a Python version.
