Cuprajake yeah it is easy to underestimate the complexity of that “feature”. It is not only tapping in a bluetooth module (and the similar gadget is sold for $500), but if you want to share profiles, you need a way to regulate water flow automatically and precisely, namely gearpump like in Acs Vesuvius.
Bianca is already $3300 in the us. Adding those features would make it well above$ 4000, losing any
competitive advantages they might have. And I think that moving into $4000 category not many people would even consider an E61
