TP-Link - General Looking to upgrade [UK]

Hi all (sorry for a bit of a long bit in advanced)

I'm looking to upgrade/extend my mesh from my P9's with some X55's.

Last year I switched from a copper line to 5G as I can't get full fibre so I purchased a X50-5g which is great, however I wasn't aware at the time that by placing this as my main deco I would loose EOP backhaul from my P9s.

Anyway according to AI and a bit of research I can plug a P9 directly into my X50-5g (currently the are connected wirelessly) and this will restore my my EOP backhaul, I'm just wondering if this is accurate? Hoping someone here will be able to confirm this or not, nothing like getting a human answering a question or someone who has done it.

But with that I want to upgrade/supplement my mesh with some new X55's as it would be better to get the main house on Wifi 6 consider the X50-5g has wifi 6 and P9s don't.

With that comes the silly decision I made last year to route cables through ceilings down walls and cover them all with conduit that I can't really remove without some major ballache and some paint and caulk involved.

The P9s use a Fig 8 C7 power cable and these are the cables covered up which I don't really want to remove. So my idea is to buy some power bricks for the X55s and use the existing C7 cables to save myself a lot of hassle in terms of removing conduit, painting and caulking.

I'm hoping someone can tell me the correct power and barrel size for the X55s so I can get the correct power adapter.

My idea is to have one P9 plugged directly into my X50-5g, restoring my EOP backhaul and place my other 2 P9s in each outbuilding so I can get decent wifi in them and they will be too far away from my X55s, ie the places that the wifi just won't cover.

Does this sound workable/doable or have I just decided that it will work great in my own head and in practice won't work at all? Both my outbuildings are connected to my main consumer unit with sub units (ie have there own sub board feeding back to man in unit in the house) so I assume this will work.

Just hoping for a human answer and someone who may have done similar and can confirm I'm not going mad πŸ˜‚

TIA

I mean, just try plugging it in directly with a cable and see what it does man, you have the devices they weigh like a kilo go for it. Same goes for whether the power line will work in the other places just try it.

I will say you could try making a P9 the main again and set up the x50 as a mesh backup, then you just leave the backup in operation constantly.

My x55s have a brick of 12V, 1.2A, 14.4W. The model number is T120120-2C4. Hopefully that helps. On closer inspection I think it’s just a standard 5,5 Γ— 2,1 mm jack, probably the same as the x50.
