Envoy integration- reversed sign of grid power

Good afternoon, I am new to this and I have just installed the solar panels with Envoy. I have Envoy (DEV) integration.
The current consumption and production sensors do not appear in the energy panel. If you recognize them with this name:
sensor.envoy_122xxxxxxxx_current_power_consumption.
Could you tell me where I should make the changes you indicate?
Thank you very much in advance.
