Hi all,

Can someone give me some help, I have an old central heater and hooked up an sensor to the burner, now I can monitor the time this is powered/on and with the som of how much gas it uses per hour i can make the calculations.
I'm aiming for an counter that counts the time the burner is on and as I have an number of how much it uses per hour/minute an extra counter that counts gas in M³
I already found some dummies where I can make the sensor but I have no clue how to create a script for this any help is appreciated.

This would perhaps something as a start: viewtopic.php?t=18848

Looks ok but aint working, thanks for the tip, getting little closer

In DzVents you can start with this

Thanks a lot, works just fine! Now search for a way to convert this to an gas volume...

Change line
iCounter.updateCounter(secondsActive)

To
iCounter.updateCounter(secondsActive*conversionfactor)

And change the virtual custom device from time to gas with units m3 (or whatever you want to use)

Works perfectly, got it all sorted now. Thanks!

One last question, is there a way to reset the counter to 0 or an specific number?

Only by editing the data in the database using sqlite or similar tool.

Sorry I was under the impression that you used a gas device type. For a counter you could try using the offset in the edit popup from the utility tab.

That works partly I think the hard way is the best way to set it to 0. delete the counter, create a new one and adjust the idx number in the script. It's a rough one but works
