As a general policy this integration only supports devices I can test against (ie. the devices that I own myself). Only so can I guarantee the proper working of this integration. I do welcome contributions that add support for new devices. So feel free to create a PR in the underlying |

Links to installation and user guides for EMMA, and mention of how it connects up, posted in Issues section. Edit: I should add, information received is that EMMA will support connecting to cloud services with the example provided being that it will be able to check for environmental / weather data (no info as to which clould service provider) and based upon this make intelligent decisions, such as ' rain / overcast day tomorrow with low expected kWh to be generated via local PC, then instruct LUNA ESS to charge overnight during offpeak when cost per kWh is lowest'. |

FYI giving the release of the EMMA in Q4 2023, the DTSU-666H, SmartLogger and Dongle look to be superceded as the "default" connectivity option for Huawei inverters/batteries etc. Given this thought it might be an idea to open a discussion upon this new product, even though pending its release currently, to allow planning / looking into it for the future.
Read below and you can work out that EMMA is collapsing the Logger functionality, the meters functions (with its 63A CT sensors, for home installs given 63A that is same as the BackupBox and its replacement the 'SmartGuard') and the network connectivity all into one 6 DIN unit. Atop of this it will also provide some additional smarts / functions.
Going forward this raises the question will WLCRS integration support this hardware (i.e. uses the same registers as now), OR will it use different registers etc and need updates in the WLCRS integration to support it? At least with Huawei merging all these functions into one bit of kit going forward, this will also mean one standard method of connectivity (at least for home installations) making support / troubleshooting etc easier.
IMHO verses all the different connectivity options (Dongle, Elfin or SmartLogger [that doesn't 100% work]) this could be a positive development and well worth upgrading from the DDSU-666H / DTSU-666H and dongle to this 'all in one' solution, whilst also adding AI/Cloud based data for automation and decision making.
EMMA-A01/A02 is Huawei's new energy management assistant, the ideal complement for a smart and efficient home with solar power systems with Huawei inverters and batteries.
Huawei EMMA-A01/A02 Power Management Assistant
With this AI-based power management assistant, Huawei provides power generation estimates based on big data such as historical data recorded by Huawei inverters or weather forecasts. Thanks to all this information, it adjusts the entire system to make it much more efficient and intelligent.
Supports heat pump and smart circuit breaker for comprehensive management of home energy use.
Supports 63A current measurement with internal CT for easy installation.
Supports scheduled mode and PV array preferences mode for best electricity savings.
Note: Trying to see if access can be gained to at least modbus register definitions for EMMA, to allow evaluation for WLCRS integration compability.
