To track my water usage, I scraped the data from my water softener by using my daily usage which is refreshed every 5min. I collect this data in a template sensor (see config below, which seems to work fine exept for 1 thing).
I sometimes have the issue that it registers a negative usage, equal to what I’ve used before. This obviously shouldn’t happen (see screenshots below). Any idea on how to fix this?
I can edit the values, however it’s always 0, there’s no negative value to be seen.
EDIT:
After further inspection it seems normal that I can’t find any negative values (see picture below). However this doesn’t explain why there’s a negative value in the energy dashboard.
I would like to push this Topic.
Is there a way to reset the counter at all, like really start from the beginning with the water meter ?
I tried som different stuff in the past, now i have a smooth running AI-on the Edge system which is working fine.
But the old stats are still there, most of the a totally inaccurate.
So, is there a way to tell HA to forget all old Data and start from new, so the history actually will make sense ?
Got the same issue, after few days of having the reader out of the network once plugged I’ve got -230m3 usage followed by actual usage next hour (like few liters).
This is rly annoying. Did you managed to fix the issue ?
