Wrong readings Smart Meter

[Felipe Braz]

I bought an Smart Meter DTS238-7 with WiFi and Tuya Chip (https://solution.tuya.com/projects/CMa84p6fctkk72), the product itself works fine but the integrations and data extracted over wifi not so much. At this moment I´m exporting about 800W of power (I have on grid solar power and I'm producing more that consuming) and the information is correctly showed in device's display but in the app and API the information keeps freezed with the last consumption that I really had (when I wasn't exporting power).
Does anyone imagine what it could be?
