Modbus

Modbus Configuration

Modbus is the protocol that Home Assistant and Energy Manager will use to access your inverter. It is important that this is configured correctly. Since Modbus is started very early in the Home Assistant startup process, it must obtain some settings from the /config/secrets.yaml file, and not from other entities within Home Assistant.

• On the left menu, select Studio Code Server

• Click Yes, I trust the authors so you can use the add-on (this is because this tool is very powerful, so only do what these instructions say)
• From the top left menu of Studio Code Server, click on the three horizontal lines, then File > Open Folder

• From the Open Folder, select config, and then OK

• Select the secrets.yaml file and then on the right side of Studio Code Server edit the contents of this file. You will need to change the {modbus_host_ip} to the IP address of your inverter. If the IP address of your inverter is 10.10.10.5, then enter this address. Do not include the {} brackets. You may need to change the modbus_port and modbus_slave entries as well, but try it with these default settings first.

• If your IP address was 10.10.10.5, then the file contents will look like this (but it is extremely unlikely this will be your address; you MUST find it yourself).

Note - You don't need to actually press save; the file is updated the moment you edit it, but you will need to restart Home Assistant for the settings to take effect.
