Home assistant energy negative values

[galamarco (Marco Galassi)]

Like reported in this tread every day I have negative valute in new energy section.

I’m using Meross LAN integration and “sensor.boiler_energy” as source for calculate kwh.
Some user suggest me to wait september for the update and I do it, but nothing has changed after 1st september update release.

I think the problem is auto reset data every day, but how can I solve this problem using Meross LAN integration source?

Here the initial discussion

Hello, i have the problem that home assistant energy is showing wrong values. For example if my photovoltaic produced 2.4kWh, import/bought 1.24kWh and exported nothing it shows wrong values like in the screenshot. The data is coming over mqtt. [image] there is the customize.yaml file: sensor.pv_energy_today: last_reset: '1970-01-01T00:00:02+00:00' device_class: energy state_class: measurement sensor.energy_import: last_reset: '1970-01-01T00:00:02+00:00' device_class: energy …

Best regards
Marco

Fix for negative values in energy consumptions

Hi, I found out today something “incorrect” in my statistics but I think I know what happened. I’m sending this email as feedback to the HA team for them to take a look at this and maybe fix the calculation of the “sum” column in the database. The history: I’ve a binary sensor installed in the gas counter. It counts every turn of the counter using a magnet. I’ve one automation counting on-off transitions of that counter and accumulating the values in a counter That counter is used as the sou…
