Hi, I've got fresh H3 Pro 15.0 installed and my COM plug is like this: Here is the link to user manual with more details. In modbus wiring quide there is nothing about such plug. Can anyone please help me to understand where I should connect 485A and 485B? I'm waiting for and planning to use Elfin EW-11. Many thanks. |

You should be using the Meter/RS485 connection (not the COM connection) and on the Meter/RS485 connector you will be connecting to the EMS485A & B pins 17 & 18 - see here https://github.com/nathanmarlor/foxess_modbus/wiki/Modbus-Wiring-Guide#connect-cable under H3 Pro |

Can you download the latest beta release of the integration and try that (i'm assuming you are running the latest stable v1.13.6?) but there are fixes in the latest beta you will need.
To do that go to HACS click on the Foxess Modbus integration and the 3 dots in the corner click the Redownload option - in the box that opens click the 'Need a different version ' and choose the latest beta release v1.14.0b3 and download that, restart your HA and then see if there are any errors - it should hopefully have fixed your kWh readings being 10x bigger as well.
