I set up an all Omada network in my house. OC200, ER604 router, and TL-SG2210MP managed switch. The switch is running three APs and a few POE cameras. Two cat6 cables were buried and run to a barn. I have an AP mounted inside the barn and a spare cat6 cable. Since the barn is metal, I'd like to install an AP on the outside to get better coverage outside. I'd also like to install a few POE cameras around the barn. Since I only have one additional cat6 cable, that wouldn't be possible in the current setup.

Could I use a TP-Link non-Omada unmanaged switch (TL-SG1005P) on one of the cat6 lines and then run the extra AP and cameras off that. I'm sure it's possible but would I be able to see the switch in the Omada app? 

Thanks in advance.
