Hello, yes. I installed firmware 269.61 patched by Coulomb: I know there is an official version from Voltronic 69.70 that solve this issue:

from https://github.com/syssi/esphome-smg-ii/blob/main/README.md

Hello, for SMX II 5.6 kW, RS485. For SMG II, RS232. easun-smx.yaml

The S/N matches with inverter sticker. Inverter has internal Wi-Fi datalogger which sends data to some cloud server. DessMonitor is a web portal where to see inverter data. It shares same data with WatchPower Wi-Fi, SmartESS, Energy-Mate, and other apps. I suppose they made some mess on cloud or they remotely upgraded datalogger firmware. I don't know. Main issue I have now is PV production and output data in kWh is no more sent.

These are screenshots of 2 deives:

Hello, same issue here for my Axpert Max 7.2. Tow instances, same S/N, same DataLogger P/N, but 2 different Dvice Protocol: 2400, 2449. On one instance I can see Total and Daily PV production and Grid Consumption till May 28th, but no other values (). In another instance all values except Production/Consumption starting from May 29th.. Issue is present on WatchPower app, Energy-Mate app, SmartESS app, DessMonitor website.

@Coulomb sorry to bother you, is there any chance to have such patch? Thanks

Hello, then, if 69.06 is better, could be patched to increase max charge current to 120A (and Max Utility Charge Current as well)? In this way I could have SoC management and 120A charge current (and 90V bug fixed). Thanks PS: when inverter is in SBU mode and is in bypass because battery voltage/soc is lower than "Return to grid" value, MPPT power goes to battery and to load at the same time, and if needed, missing current for load took from grid. Is there a way to let inverter MPPT to charge only battery and let grid to feed only output loads (when in bypass), without mixing solar power and grid power into loads, maybe with a fw patch? I'm asking this because in Italy is not allowed to feed loads from solar and go in parallel with grid at the same time using an off-grid inverter (we need an on-grid inverter certified for italian regulations).

Hello, finally I received original firmware from my vendor: 88.03. Differences I can see, comparing with version 69.61: Max Charge current 69.91: 80A 88.03: 120A Back To Grid, Re-Discharge, Cut-Off (parameters 12, 13, 29) when supported battery connected: 69.61: parameters are i SoC % 88.03: parameters are in V Could this firmware be patched for 90V bug, please? Could parameters be changed to use SoC %? Thanks MAX_7.2K_88.03.7z

Hello, I installed version 269.61 yesterday. Now I can see Voltage differences on morning and afternoon. Before upgrade (sunny day): After upgrade (cloudy morning): Thanks

Thanks @Coulomb I'm waiting for original 88.02 from my supplier. Meanwhile I will try 269.61 (69.61)(Voltronic version numbering is quite confusing). Is safer to upgrade from USB On-the-GO or PC via RS232?

Hello, I confirm I have DSP 28066 and this new firmware 69.06 was updated by supplier on my inverter and that now I can select charge current at max 80A, instead of 120A of previous version (88.02). I have the impression 90V bug has not been solved Could this be patched, please?

This is fw they installed MAX_7.2K_69.06.7z Could you check, please? They told me that this has 80A charge limit (against 120A of 88.02), has SoC % for parameters 12, 13, 29 when battery type <> USER. Could you check, please?

Hello, finally my supplier has updated my inverter firmware from 88.02 to 69.06 (DSP 28066) to solve 90V bug. I will check next days if it truly solves this bug and let you know. I requested also to have original 88.02, so should be patched, but not yet received.

Thanks, I confirm now it works
