Hi Tsa,
I only have an e-mail address - don't know if anyone is actually receiving these mails on that account, because I haven't received anything back from them yet.  But then I haven't asked them anything yet - just copied them in the mails to Mahone.
It's this one, from their website growatt.co.za :

Hi Tsa,
On Friday evening @ 21:00, it started sending data again.  Nothing changed around that time (Line mode, battery 100% charged), notmal load etc...
BUT - it only sent 3 measurements (15 minutes' data) and then stopped again.  Until now, nothing at all.
Switch from Li to USE, and all is well.  This is so damn frustrating - I don't want to run it in USE mode just so I can see telemetry data, because I'm worried this might perhaps have a negative impact on the Lithium battery.
Regarding your tripping problem - do you have the latest firmware loaded on your Dyness' BMS ?  I found out about some bug in that firmware, but in order to fix it they have to come out to your premises to update the firmware as well as some PCB in there (I read this in another thread).  Apparently on the Powerbox (and I assume the others as well), they still have to go out and do this after the lockdown.  I checked with the local importer (Andy), and he asked me to take a pic of the inside of the box.  Then he let me know mine is already updated in terms of hardware and firmware (he can see some negative cable installed, which the older ones don't have yet).
Regarding the "BMS software" - I assume it's some part of the firmware that handles communication with the BMS.  It was also just a .bin file he sent me (like the firmware update), loaded using the same utility app.
Yes, my BOF function doesn't work anymore after the update.  It beeps when you press the buttons, regardless that setting.
I haven't had any reply from Mahone again, after the last time I sent him more information regarding the Wi-Fi problem on Thursday.

Hi,
Yes, I'm experiencing the same kind of problem at the moment. I have a SPF 5000TL HVM-P inverter with Dyness Powerbox F-10.0 battery. These were purchased just a few days before the lockdown, so they could probably be from the latest batch.
When the inverter is set up correctly to communicate with the Lithium battery, the Wi-Fi data logger malfunctions and no data gets sent to the server.
When I change the battery type setting on the inverter to USER or AGM or pretty much any setting that does not communicate with a BMS, the Wi-Fi logger works perfectly and data is sent to the server, no problem.
Change back to Lithium (Li01 in my case), and the Wi-Fi logger stops sending data immediately.
When logged onto the server, I can see that the Wi-Fi logger's Connect Status is reported as "Connection". The inverter (under "Storage") is reported as "LOST".
I have tried everything. Even sent videos to Growatt technical support (engineer by the name of "Mahone"), and he sent me the latest firmware + BMS comms software. I updated the unit with this firmware, but still no luck.
I'm now waiting for Mahone's response to my latest mail giving him this news...
Perhaps if you're willing to try and see if your unit sends data when you change the battery seting to SLA or something, then at least we could get to a point where it can be proved that this problem isn't just an isolated case ?
