Hi,
I have a T8-G3 inverter installation with 20+ solar panels and a Meter DTSU666.
In the IOS app, as well as the Fox ESS portal, the Load Consumption, Grid Imported and Grid Exported cards are always with zero, even when the immediate values as Grid Export (in the graph) shows values - see attached image.
I want to control and confirm not only the consumption but also the exported energy to the grid.
Why can't I get those accumulated values (day, month, ...)? Am I missing any other HW? Is that a configuration/installation problem? I have seen the app dashboards (with a FOX ESS KH10 inverter) and all those values and counters are there with the right values.
Thanks
Sadly the solar only inverters other than real time values and graphs don't record statistics for daily, weekly etc.. on load, grid consumption, Feed in etc.. - Fox have confirmed that only Hybrid inverters store long term statistics.

If you have a home assistant using the cloud interface you will be able to use that instead to record the statistics

Hi Dave, thanks for your reply - that post you referred is about the same thing. This is really strange how a system like this one can measure the instant and not the cumulative FeedIn (as it does with the Solar Power).
I have a Home Assistant Green and I'm trying to have that calculated somehow - like a table "Day 1 - ∑FeedIn; Day 2 - ∑FeedIn" so I can control how much power I'm selling to the grid. No luck till now.
Maybe I will need a Shelly or similar to have this. The support has suggested to have a "FoxESS Chint Gateway" because of nights (when the inverter goes off) but with all these news I'm not sure it will make it better.
Thanks in advance

With the home assistant you should have the power readings (whilst it is on-line), to get what you need you will have to first create a sensor that converts from power (kW) to energy (kWh), that is done using an integral (‘riemann sum’) - home assistant provides the tools to do that, I noted something here in this post to do that using ‘Helpers’ - just make sure you have the entity id of the sensor your want to use as the source i.e. ‘sensor.foxess_grid_consumption_power’ to create an energy counter for grid consumption and follow the steps listed here https://github.com/macxq/foxess-ha/iss ... 2406963427.
That will create a counter that continuously increments with grid consumption power and if you add it to your energy dashboard that will show the daily, weekly, monthly values for you.
You can also create a daily total using the helpers mentioned above, this time use the energy sensor name you have just created as the source and create a ‘Utility Meter’ for the reset cycle choose daily - and save it, that will give you excatly what you should have had from the Fox cloud a sensor that shows your grid consumption daily.
And once your happy you have what you want you can repeat for Feedin and Load sensors to get daily export and house load sensors.
