Hi,
have you manage to solve problem with total energy 0 value?

cristitttt · October 3, 2024, 8:51am

please help me with integration i try a lot and don"t work
i try with modbus seriel i see the sensor but no value
i try with esp 32 and don<t work .

The integration

doesn`t work anymore as modbus seems to be outdated. Several unanswered issues opened at Github since January 2025

E.Antonsson · May 14, 2025, 7:43pm

Hi, do you get it to work? The communication thru Modbus TCP between Smartlogger and home assist?
