Viega Wannenfüllamatur Tro E3

[Roeller]

Hello,

I have recently build a project with a Fantastic Bathroom with 2x Viega Trio. It really looks like a dream! I will post a video.

The Viega Trio WIFI module will be discontinued (and there will not be a follow-up device, they will not stop the Trio product, but just the Wifi unit because it was made by Oblamatik AG and that's Viega Swiss now, however, they moved a lot and decided to stop development for this thing)

but no problem!

I 'broke in' on the Wifi module, copied all files.. and have sniffed the BUS traffic (which is 9600baud rx/tx). Then I ordered the same connectors as the Display and the Wifi Module uses, and I am working on a very small (esp like) device which you can put between the display and the main unit.

You can even put it between the display and the main unit when you already have a wifi module connected.

I have documented my project here: https://github.com/roelbroersma/viega_multiplex_trio_e (about breaking in on the unit.. making photos.. and downloading all the files)

They wanted to stop the whole line or at least upgrade the electronics for years now.
Guess it's still selling well enough for now - or they have enough stock

That sounds great!
So given someone hacks together the right hardware, we could leave out the WiFi and connect this to LAN or even KNX?
Do you see any chance of writing to the file system of the Carambola2, so I could re-brand my modules? Maybe try to add a LAN port?
Too bad all the update servers are gone already.

Did you by any chance also play with the debug port of the main device or figure out the communications of the controls?
