Describe your problem Strange values after solar panel installation

Hardware information:

Meter: Aidon Sweden
AMS reader: ESP8266

Relevant firmware information:

Version: 2.0.4
MQTT: yes
HAN GPIO: UART2

Yesterday I got my solar panels installed and connected to the grid, and now the meter report very strange readings on my Phase current. Have anyone seen this behavior before?

gskjold commented 2 years ago

Thanks, I see now that current values pass through a unsigned int, will fix in next patch.

Isaksson commented 2 years ago

Yes, I just verified on my meter and its because the current has a negative value now when exporting to the grid. Thanks.

Thanks for that, just installed the update, I used my mobile phone really nice to be able to update from mobile device 👍 Let's hope for some sun tomorrow so that I could verify this new version.
