Hardware Questions and Recommendations

Is there any support for OpenWrt possible?

I have bought this product, it's just a good device with a clean, responsive web interface. An Emulator of the web interface can be found here [1].

Firmware seems to be an outdated OpenWrt version as you can see the typical stok URL parameter?

As of https://fccid.io/TE7C2300V2 it seems to have the following components:
SOC: MT7621AT
WLAN-Hardware: MT7615N (2x)

That should be possible, but someone -you- with the device on their desk will have to put in the hard work and do the development for this device.
