Try it out.
For me its not possible anymore to use the Nefit service key.
I get a UBA error or something and the program aborts
But it probably work for you and then its possible to get a lot of data form the nefit.

Hi all,
I'm looking for the opentherm protocol specification 3.0.
I requested it to the opentherm association but they said that it is available only to the members.
Can anyone help me to find it? Any link?
Thank you

Hi all,
Recently I connected together Viessmann Vitodens 100-W, De Dietriech iSense (originally Remeha I think) and OpenTherm Gateway. Generally, it works great:)
I join to kindly request of Alexcat about sharing open-therm specification in. v.3, which can route me to discovering what do mean such OT messages: 99,109,110,111,112.I also have impression, that some of DHW functions do not work as I expect
Maybe someone has that file close at hand?
Thanks!
Artur
