I have a house and a garage that are approximately 60 meters apart. In the house, I have 2 x Deco BE65 units set up in a mesh network. I’d like to have Wi-Fi coverage in my garage, but without the need to bury a network cable. Is it possible to set up a Deco X50 Outdoor and connect it wirelessly to my indoor mesh network using one or two Wi-Fi range extenders, such as an RE815XE?

I can use a network cable between the BE65 and an RE815XE, and similarly between the Deco X50 and an RE815XE. My question is whether it’s necessary to have a Deco X50 in the garage, or if it would suffice to use just an RE815XE for Wi-Fi coverage in the garage?
