TP-link EAP225 Older Model wifi AP

Bought on carousell for 120 dollars (https://www.carousell.com.hk/p/tp-link-eap-225-%E8%88%8A%E6%AC%BE-wifi-ap-1192858799/). After connecting, the omada controller is too new, showing a warning of compatibility issue with this device. The EAP225 (v1.0/2.0) no longer has any newer firmware available (1.4.0), and I don't have an older version of the omada controller, so it cannot be used. No power adapter included, powered by POE. Message me with any exchange proposal, meet-up for pickup at Long Ping / To Kwa Wan / Sung Wong Toi.
