Condition if value increaded by X

[sonic igloo]

I am trying to create an automation for an alarm when the water consumption has increased by X in the last X minutes.

Unfortunately, I do not know how to build the condition here.

I would be grateful for any help.

you can use a helper create a derivative sensor for your water consumption data. then automate on that when the rate of change increases.

Hmm... Sound like the perfect function for that task.
But I am unsure what to set:

The "wassercounter" gets an increment for every 10 liters of water.
the water consumption is not permanently on. But only when flowers etc. are watered.
This would therefore be a useful scenario. Check the consumption every 30 minutes. In other words, if 100 liters are consumed within the last 30 minutes, give an alarm.
So if 10 increments occur on "wassercounter in less than 30 mins.

there is some info about what the options mean in the documentation but it might need a bit of trial and error to be fair

ok I will test a bit.
Thx for the tip.
