Is your H3 firmware up to date? |

That isn’t being recognised as a standard H3 ‘H3-10.0-E’ , is this a variant / provided under licence H3 inverter There’s something strange as your Manager is 1.87 but the H3 latest release is at 1.85 ?? |

Actually, I have another question related to my "OH3" variant of the H3 inverter. My total loads sensor (for example, sensor.h3_inverter_load_power_r ) reports exactly the same value as my EPS load sensors ( for example, sensor.h3_inverter_eps_power_r), and for all three phases. The EPS value seems about right, so I'm guessing that the total load sensor device ID is configured incorrectly. i.e. pointing to the same (but wrong) RS485 address as the EPS sensor. Where in the YAML files can I find those addresses, and any idea where can I find the correct address for my total loads so I can modify the YAML? |

Just wired up my EW11 to my H3, and I get this error message during the setup of the modbus integration in HA. Seems very odd that it can communicate enough with the inverter to know what model it is, but then not be able to connect. Any ideas? I know the EW11 is working because I can browse to its web control panel. Thanks.
