Hi sklas,

do you have any experience in how far the software and electronics of the "Jura Impressa 50" and the "Krups Orchestro Typ 889" are the same? I think both machines are almost identical looking at the mechanical design.

I just ordered a WeMos D1 Mini V2 and will try to integrate it into the machine following your instructions. Thank you for your work :) I'll report how it worked with the Orchestro.

Update:

I got my WeMos D1 Mini and connected it to my Krups Orchestro 889.

Sadly (but somehow as expected) it does not work right away. The Machine doesn't seem to "understand" most of the commands. I tried "RE:" and "RR:" with the adresses from 0x00 to 0xFF, some "AN:", some "FA:" and some "FN:".

So far I was able to find three commands the machine understands/answers:

All the other commands (I tested so far) don't cause any reaction.

For all "RE" requests (but 33 and 7F) the Machine at least answers with "re:". The "RR", "AN", "FA" and "FN" commands are not beeing answered at all.

Could you check what your machine answers to "TY:"? Do you have any Idea why my machine would answer only those two read requests and the type? They wouldn't develope a firmware with a service port that provides that few information would they?
