Discharging remains disabled

[colyro]

Hello

I've a deye inverter 12k-SG05LP3 with 3x 320Ah battery packs in parallel based on a JK v19 BMS.
Between Inverter and batteries bussbar I have a victron smartshunt for an accurate SoC.

To translate the Smartshunt SoC into inverter, i am using a lillygo tcan485 flashed with DiyBatteryBMS-esp32-ESPCAN-20260218-2119.zip.

The most critical issue that I have is that the discharching option is OFF and I cannot enable it, hence I cannot use the solution.
No errors/issues on the inverter or Logs section in web UI.

Apart of that, neither Request Flags Enable (0x308 Status) option is not staying checked. So I assume somewhere is an issue in communication with the inverter.

What could be the issue? Bug or missconfiguration?

I just did some testing, when the Low SOC is set to 0 then discharging was turned off even though the battery is at 100%. At Low SOC set to 1 or above the discharging turned on. So set your Low SOC to above 0 and retry.

Doesn't do that for me but try what @kommando828 has suggested, do you have home assistant setup and connected? @colyro

@kommando828 - setting low soc to 1 instead of 0 did the trick and now it is discharging plus showing right values for charging/discharging as they set in BMS section -> thank you!
It is by design actinge like that or its a bug?

@sijones - it is not connected to anything apart of SMartshunt. no HA integration (yet) as my intention is just to use it as a proxy of injecting smartshunt data into deye.

Now the only issue remains that "Request Flags Enable (0x308 Status)" does not stay ticked (ON). after 10-15 seconds, it is unticking itself.

open the console of the web browser - F12, have a look and see if it's sending the change, copy paste the console here.

like this?

Console not source.

Need to see the loading of the webpage and then the flow, generally the switch going off means the frontend never sent the setting.

first image from above is from console. the second is from source where i've clicked on the red issue -> Uncaught Refference error. or there is another console? sorry, F12 function beat me since years

@sijones - Is this the info that you've requested or it is in another place?
