New Firmware seems to have disabled MODBUS TCP via V5 Protocol #8
Description
Thanks for the work!
Unfortunately it does not work anymore, as the new firmware >2.x seems to answer the V5-request with AT.
See https://github.com/kbialek/deye-inverter-mqtt/issues/127
so it seems one has to switch over to AT on Port 48899.
Only in a short 5 sec timewindow, after reboot, when you change the Internal server parameters setting on the config_hide.html page from TCP-Client back to TCP-Server - it will answer "right" - so they have not disabled V5, just "hidden" it behind the AT. - See the output below.
