Jose,
I placed my Cerbo in the space behind the main battery switches and mounted it using DIN 35 mm rails. I placed this as well as two relays for starting the generator based on SOC and commands from the Cerbo. I also used the GX display which is hardwired and mounted that to the face of the bookshelf right behind the navigation seat.
The Ruuvi discs are mounted in the freezers and refrigerators using the 3M command strips with Velcro on one side so I can easily pull them to update firmware and more importantly, change out the batteries.
I’m attaching some screenshots of the install on Aventura. Disregard the actual temperatures since she is sleeping for the winter and I haven’t turned on the systems so those are ambient temperatures.

Thanks, Doug Smith
