ENERGY_Total gets truncated to 3 decimals on every date rollover (i.e. at midnight)

[MaxRower]

PROBLEM DESCRIPTION

When I view the graph of ENGERY_Total of my various NOUS A1T plugs, I can see a small drop on every date rollover at midnight. After examining the data in influxdb, I can see, the reported value of ENERGY_Total get's truncated to 3 decimal digits on every date rollover. I have configured to use 5 decimal digits.

TO REPRODUCE

Steps to reproduce the behavior: set EnergyRes 5 and wait for a date rollover

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen. The value of ENERGY_Total should increase constantly, without any drops in between

SCREENSHOTS

If applicable, add screenshots to help explain your problem. Timestamps in influxdb seem to be UTC, so they are one hour off from local time.

[MaxRower]

Well, I checked the values of another plug, it only decreases there, but not truncated to exactly 3 decimals. So maybe some sort of binary truncation actually.

And that produces some weird results in grafana:

[sfromis]

I'm also seeing occasional small drops in "Total" energy at midnight, on some devices, including one with a very stable consumption pattern, without the total being over the about 7 digits of available resolution with single precision floating point.

{"Time":"2024-02-04T23:56:32.323+01:00","ENERGY":{"TotalStartTime":"2022-11-08T17:55:27","Total":44.79066,"Yesterday":0.12747,"Today":0.12666,"Period":0.440,"Power":4.900,"ApparentPower":14.692,"ReactivePower":13.900,"Factor":0.33,"Voltage":233.200,"Current":0.063}}

As designed.

On ESP8266 the total energy is stored in an uint32_t for legacy reasons with max three decimals to allow a max value of +/-2147483.647 kWh On ESP32 total energy stored as a float to allow a max value of +/-262143.99 kWh

[stefanbode]

I assume that not the limited decimals are the problem, but that on midnight when storing the daily consumption into total there is a jump.

[stefanbode]

I was able to find this also on my devices but only on the ones with super low power consumption. If there s e.g. 50w, you see nothing.

[sfromis]

With Default TelePeriod of 5 minutes, you'd not see a fall in first payload after midnight, if consumption since midnight is more than the lost decimals. I suppose that you'd still miss up to 1 Wh in the total.

[sfromis]

What I gather is that the internal "Total" value always only has 3 decimals (1 Wh resolution), and when the "Total" value appearing in TelePeriod payloads can have more than 3 decimals, this is due to it being the value updated at last midnight plus the "Today" value, thus allowing extra decimals from the "Today" accumulation since midnight.

This has not been bothering me, as I hardly use the "Total" value, due to this getting low on decimals when total consuption gets into the MWh range (which would be 9 digits when wanting 5 decimals), not allowing full resolution in a float. Hence my plots are based on differences in the "Today" value accumulated over time, without lowering decimals.

[BigAl66]

Did anybody found a solution? I have the same problem here. Every modnight some of my NOUS A1Z have the dame issue. Unfortunately Home Assistant cannot be configured to ignore negative values... (I didn't find at least an option for that...).
