I tried it but not working for me now.  I need buy new Wifi-LAN Kit 2.0 Dongle i think, because do not work for my Goodwee ET 10kw  series but I do not know is this dongke is compatible with my goodwe. I have comunication on UDP and port 8899 not 502.

you need first to update firmware (ARM Firmware) of your ET, before you insert new dongle. With old firmware it will not get recognized, and it will not even allpw you any firmware updates.

You have to buy "GoodWe Wifi+LAN 2.0 Cyber Security Dongle" and not the "GoodWe Wifi+LAN 2.0 Dongle", see attached compatibility list

Thanks, But i do not need buy new dongle. I have my dongle and I made QA via UDB port 8899 some years ago.  I posted the QA here. But this new QA via modbus port 502  has some good functions  what i need. It is battery from greed, salefirst, battery First a grid First.  It is what i need what kind of commands are sent to goodwe for change mode.

I also create Fibaro Dashboard on html page . which loads entities from Fibaro. I would like to add cameras that I have on the network there but I don't know how yet. Any ideas on how to improve the dashboard or how to use cameras that are on the local network. I can get the image via vlc and rtsp but how to get it to my local site?
