Device history overview

[fervefdsv 0]

Hello, is there some place in HC3 where I can see history of a device - i.e. daily kWh, or when the device was on/off, etc. The /app/history is nice, but more like a log dump. I can't filter only one device or see some nice summary (i.e. for the kWh).

in configuration -> advanced device only right now, we are working on classical energy panel on phone

OK, that would be nice. Maybe also extending the export options. I checked the General > Data Export and the resulting csv file, sadly, contains only W and not kWh, which, for a long term monitoring, is more interesting.

Hello @A.SochaIs it possible to access the history of a specific device via a HTTP request? And maybe get the response in JSON? I could not find a way to do this in the documentation.
I have a POPP weather station and I would like to create a graph of temperatures, pressure etc.

@josjg pay attention

POPP meteo station is "sleepy-head" device, particularly when nigth.

I was have a some issues with this meteostation... now not. ? selled.

Thanks for your answers! I was able to dril down into the table to get the barometer values. That should basically get me underway.

Do you know if there is a way to intercept an event when it's fired? In my case that would be a DevicePropertyUpdatedEvent.

Let me re-phrase my question: Is there a way to intercept the event at the very moment it is fired? Is there a hook into (any, or specifically the DevicePropertyUpdatedEvent ) event that I can use in a Quickapp, the same way as one can hook into (a restricted selection of) events in block and lua scenes?

It would just be a refinement of course, because the easy work-around to create any sort history graph would be to get the event history the way @10der shows at specific intervals.

Jan ( @jgab ) already said about this. No native development instruments to hook events in QA

one way looping in QA and getting and analyzing response from api endpoint “refreshstate”

alas

Well, you can try this.

Install this QA (Event Watcher) - no need to configure it.

In your other QA that wants to receive device property changed event do this:

Please login or register to see this code.

The EventWatcher QA will call other QAs that have an QuickApp:EVENT function with new events. If there is a comment with the format "--[[ Triggers: ... --]]" it will use the defined json templates to filter the events (in this case we are only interested in events of type device and id 66). If there is no templates, the QA will receive all triggers.

 

Btw, from an external system you could also poll the HC3 with /api/refreshStates - you get all new events and you filter it yourself with respect to what events you are interested in.

Thanks a lot! I see that I will have a busy weekend and have to learn a lot ?
