Sauna control inside sauna

[BDP]

Hello,

I'm in the process of "designing" my own sauna controlled by Loxone, but I'm struggling with a control inside the sauna.
On the outside I will mount a flex tree, but I'm not sure inside.
I'm making my own "autodose system" to apply water and fragrance on the heated stones, so I need some control inside the sauna as well.
I prefer a flex tree (change temperature, music control, etc..), but maybe not the best option keeping temperature inside the sauna in mind.
Does someone have other ideas?

Why not use a Touch Surface? It has 6 freely configurable surfaces. You can engrave the inside (in the sauna) in the wood or, even better, have it lasered... If 5 or 6 inputs are not enough for you, then you will probably have to make something yourself or mount the Touch Pure Flex somehow waterproof in the sauna. No guarantee from me that it will last long...
