The Deco 9 should be compatible and expandable with any Deco product. This means that a single unit of a Deco product can also be purchased and integrated.
The Deco systems can be expanded with any other model, i.e. it may make sense to combine a set of 2 Deco M4s or even E4s with the system and thus perhaps achieve even better coverage with more units. A single P9 should cost about the same as a set of 2 M4s or 3 E4s. Some of the individual devices cost almost more than a set of 2.

Hello,
Are you on three-phase? Are all the Decos on the same phase? - If not, you need to install a phase coupler in the electrical panel. Having said that, Deco operation is sometimes erratic. I also have one that connects to the PLC intermittently. It seems to be the system that decides which is the optimum link (Wifi/CPL) between the main Deco and the satellite Deco, but I haven't managed to work out what the criterion is yet. In general, pulling the satellite plug out and putting it back in is enough to re-establish the PLC connection (a bit basic, but if it works...).

A restart of the main router will probably help. Otherwise, the P9 can be reset and reconfigured.
I also experienced the same but for only 1 unit. It goes offline and can't connect with the power line or wifi, this happens randomly .
Unfortunately, there is no manual. I only found these two links with FAQ's:

Yes, it is compatible. Each P9 router has two 1 Gbit/s ports.
It’s a 2 pin plug so works with both
Hello Cwalwal,
Yep, all three can be connected with an Ethernet cable.
Can only recommend the product!
Greetings
Well, I've already noticed that it's never worth buying a set of 2. You can get a set of 3 for a little more, or vice versa, you can even get a set of 3 for less (like the Deco M5). However, I don't think that the prices for a set of 2 would be lowered because of that. Therefore, I would always go for the 3-piece set, because you get more for almost the same or less and you can quickly expand at home if necessary because you already have a third device and if two are enough, you already have a spare part at home if something should break :).
