Describe your feature request

As per the EMMA feature request, this 'issue' is intended as a placeholder to allow the gathering of information and discussion re the forthcoming SmartGuard-63A- S0/AUS0 (also referred to as 'BackupBoxA' on Huawei Support Site), that will supercede the current BackupBox device, that provides automatic grid outage failover for LUNA ESS users, with the provision of a single protected phase.

As per the other new products, this will require the release of the modbus register definitions for this product, at which stage we can see if they are the same as the current BackupBox, potentially meaning WLCRS will be 'out of the box' compatible with the SmartGuard, or if additional effort would be required to support it. At which point review of the registers would need to be done and put forward to see if any provide any useful functionality, or not.

Documentation available currently:
BackupBoxA V100R023C10 Communication Matrix.pdf
BackupBoxA V100R023C10 Open Source Software Notice.docx
BackupBoxA V100R023C10 Release Notes.pdf
BackupBoxA V100R023C10 Security Maintenance Manual.pdf
BackupBoxA V100R023C10 Upgrade Guide.pdf

Note: From the communication matrix above, it already confirms that the SmartGuard connects via RS485 to the EMMA device, that in turn connects via RS485 to the inverter(s) / LUNA. Additionally the SmartGuard enclosure includes a DIN rail for mounting the EMMA inside of it (though you can install EMMA without a SmartGuard, for non LUNA users). From this it appears that in future installations of LUNA that want to operate in an off-grid/outage situation, will be expected to deploy Inverter(s)+LUNA ESS+EMMA+SmartGuard by default.

Some new information released at: https://solar.huawei.com/en/professionals/all-products/HUAWEI-SmartGuard

Instead of previously having to deploy a Backup-Box and a DDSU/DTSU-666H meter (and optional SmartLogger), the EMMA product is now included as part of the SmartGuard, providing 'Smart' functions and also the ability to shed load (via Shelly PM/Pro devices). Looking at the User Manual and the wiring diagrams, this however appears to remove the option of using CT's to monitor the power (as the standalone EMMA allows for), with the SmartGuard having the inverter, backed up and non backed up loads and a connection for the grid to be connected to it, Huawei designed it so the EMMA is intetgrated into these connections.

Hi there.

I just downloaded the latest MODBUS interface definiton and communication matrix for the EMMA 2.0 with Smartguard, also known in the Fusionsolar app as SmartHEMS. Maybe theese files can help. If needed i can help with testing as i have a system installed at my house. I never coded anything for HA so i'm a bit lost on that side.

@menyhartda This refers to EMMA and firmware version V100R024C00SPC100, please have a read through the above thread, as I believe this is the version of firmware (and V100R024C00SPC102) that people have working already, based upon WLCRS Integration v1.5.1

Hi! Anyone managed to get it working with the smartguard? When i try to install the integration i get this error:

Initial support for EMMA has been added with the release of v1.5.x, however SmartGuard is a different product to EMMA, for which I believe support has NOT been added to WLCRS integration.
I believe that we are still pending finding the Modbus register details for SmartGuard, that would be required to allow adding support for SmartGuard.

As SmartGuard is the new version of the Backup Box, your install overall should be able to work with WLCRS, if connecting to the inverters via the sDongle / EMMA, albeit without the status / controls of the SmartGuard indicating being operating On/Off Grid etc.

Thanks for your reply. I'm trying to connect to the emma that is incorporated in the Smartguard so maybe this Emma is another device and thats why it doesnt work.

The SmartGuard has an EMMA 'bundled' into it, but from a wiring perspective you should be connecting to the IP address / Modbus port of the EMMA. IMHO I would think it should work, just that WLCRS would not currently be able to 'understand' or know which Modbus registers to pot serially query, to talk with the BackupBox component of SmartGuard, so it could now if it's on grid power / grid offline etc..?

I can confirm that it doesnt work (i expected the same as you). It doesnt connect.

i did manage to connect via the IP address of the Smartguard. But the data
coming back (probably as only theese are programmed within the Modbus
registers) is only from the MAP0 inverter and the Batteries. Nothing in the
EMMA and it smartmeter and nothing on the SMARTGUARD. However the fact the
the system is on-gid or off grid can be seen in the Inverter registers.

Daniel, Menyhart.

can you share how did you connect to the Emma? I followed the instructions of the wiki and continue getting the error of the log
