Hi,

I have recently started to upgrade to omada based devices from the existing home tp-link devices, however, I am now getting internet connectivity issues from a Growatt Data Logger device on the network.

At the moment the setup is simple
ER605 -> TP-Link switch -> EAP670 + TP-Link ArcherA8

After days of troubleshooting, 

I tried the following, which worked.

Used just the old TP-link Archer A8 (home wifi router), factory reset device, plugged in NBN cable and configured PPPoE, disabled 5GHz wifi channel, attached laptop, and the Growatt Data Logger SUCCESSFULLY attached to the 2.4GHz channel

A very simple setup, and confirmed the data logger works

Without factory resetting the TP-Link ArcherA8, I disabled the WAN & DHCP, changed it to another static IP and attached it back to the original solution (see above).
It is just acting as an Access Point (AP)

The Growatt Data Logger is still attached to the Archer A8 Wifi, but it will not connect over the internet to the Growatt servers. I can connect my laptop to the Archer A8 wifi and the internet is fine.

It seems that there is some config on the ER605 that is blocking communication to the Growatt server on the internet.

I went onto online chat with TP-Link support but they have not answered in 4 hours.

I am looking for advice on what I need to change to fix the issue or configure on the ER605 for better logging.
