Smartmeter negative values for current power

[zoeste]

In the Homey Energy overview, my Fronius smartmeters appears with negative values for current powerr. As a result, its consumption is not accurately accounted for. How can I address this issue or adjust the values to be positive?

Hi Zoeste I can't help you with your question. But maybe you can help me? I can't get data from my smartmeter; I see you can. Can you give me a hint?

[zoeste]

I simply added a new device of the type "Smartmeter" and entered the IP address of the inverter. I then immediately received the data.

Is there no news on my question yet?

Hi. Could you please post the result of http://<your_ip>/solar_api/v1/GetMeterRealtimeData.cgi?Scope=System ?

Thanks

Of course, here is the result:

Can we expect any news on the subject?

[ThomasHoussin]

Hi ; I don't know if it's still useful but can you explain what you expect to see ? In the example sent you do have 2 negative values "PowerReal_P_Sum" : 668.44549560546875, , "PowerReal_P_Sum" : -514.10000000000002, "PowerReal_P_Sum" : -144.40000000000001,

The power meters are reporting two negative values (depending on where they're installed, it could means you are injecting in power grid) ; as you have several power meter, be aware that they're cumulative by default. You can change that in the device options. By cumulative that's what homey means :

Certain devices, such as a P1 meter or a current clamp, can measure the total energy usage of a home or a specific power group. Their measurements contribute to the overall energy consumption data for the entire home. To mark a device that measures cumulative energy usage, set the cumulative property to true in your driver's configuration.
