Tp-link deco 9 plus

Hello all,
I would like to know if there are any plans to develop any firmware for this kind of device?

thank you

there are never plans, people who own them do it.

or they donate one, to a developer, to get them added.

Ok, I will understand your replay as "there is none working on it".
thank you

there could be an open ticket at github for getting them added, it wouldn't show here, obviously,
and I haven't looked for one.

but yes, your assessment's correct.
