HTML version: 6.8.0

Issue: I've installed and configured water meter yesterday and everything worked ok. Today I've found out that it shows wrong corrected value or it rather shows only decimals unlike raw value which has right value.

Here are readings: all_readings

jomjol commented 3 years ago

Did you set the prevalue?

domborovicova commented 3 years ago

Did you set the prevalue?

Yea at the beginning I set it to 732.2 I believe.

jomjol commented 3 years ago

Maybe there was a wrong detection on the digits. I would suggest to set the following parameters

AllowNegativeRates = false
MaxRateValue = 0.5

Disabling AllowNegativeRate will ensure, that the counter is not running backwards, so if a "0" is detected, this will be detected as false reading. MaxRateValue limits the maximum change to the upper, so if the detected number is much to big, this will be ignored also. The right number depends on your maximum water consumption and reading intervall. That should make your reading much more stable.
