Your contribution

Added the board from @Bouni to my Neff oven B15P42N3/01. The machine is from the year 2013.

Here are some Pictures:

From the inside:
Red markings are dbus connectors:
(I should have taken the photos after dedusting...)

The red marked port I used to connect the RAST connector.
Pins are from left to right:
VBUS | DATA | GND

This devices communicates with a baud rate of 19200.

The first sensors reported in ESPHome:

Right now it can detect the operation modes (except of two). Light on/off, target temperature, current temperature (reported every 5 seconds), blower on/off and power state.

Thanks for sharing!

• The oven sadly does not have a convenient external D-Bus connector, right?

• I wonder how BSH ensures that the connectors do not slide left or right on the PCB. It looks like the PCB has a cutout on the left side of the connector area, which a tab from the connector then hooks into — is that correct? @Bouni

• Do you see any frames on the bus when you change the clock (same question for the steamer)?

Sadly no port you can reach without opening.

Yes the pcb has some small cuts that prevent to slide sideways.
For this device I chose the port that was placed deeper in the pcb, so that the connector fits perfect between the cutout.

Right now I see nothing when I change the clock, maybe if I dump all messages….
