Current sensor does not detect current direction
Hello,
I have a question regarding the current/power sensor on my KinCony device.
The circuit is connected to a 1100 W pump, with approximately 1000 W peak solar PV production.
I expected the sensor to detect the direction of the current and therefore show negative power when the solar panels are producing energy and sending it back through the circuit.
In the attached screenshot:
- Green area: nighttime. The pump is running and consuming approximately 1100 W. This is normal.
- Red area: daytime. The solar panels are producing around 400 W, with no consumption from the pump. However, the sensor still reports the power as positive instead of negative.
Is this sensor supposed to be bidirectional?
If so, is there a specific orientation for the current transformer/sensor, or does it require a particular configuration to detect the direction of the current?
Could someone explain how the current direction is detected and how I should configure or install the sensor to obtain positive values for consumption and negative values for solar production?
Thank you.

download newest ARM CPU firmware by USB-RS485 adapter. so that will support negative value.
here is firmware link: https://www.kincony.com/forum/showthread.php?tid=9171

I have this firmware but running with esphome
