config files for Bulex heater (and/or MIgo thermostat) somewhere reverse engineered already?

[netweaver1970]

Hi,
Last year I installed the EBUS Adapter 3 + Wemos D1 in a more manual install of HomeAssistant. I got something working by then, but the difficulty of finding all correct values + other issues made me to freeze the project.
Today I got the new HA integration working (-sometimes-, see new issue for this) in a proper Add-on fashion on a new HASS-OS install, kudos for @john30, so I got renewed energy to finally try to tame this beast and get all out what I would like + control it as I want.

But I still have the same issues as last year, my Bulex Themacondens heater is not properly recognized so the config falls back to a (generic) Vaillant BAI. And my thermostat is not recognized at all.
Did anyone work on custom config files for these (Belgian) Heaters? Below is the snippet from the log.

Address 3/8 is the Bulex ThemaCondens heater, Address 10/15 is the Bulex Migo (aka Vaillant vSmart, aka Saunier Duval Migo, aka older version of the Netatmo Smart thermostat).

address 03: master #11
address 08: slave #11, scanned "MF=Vaillant;ID=BAI00;SW=0602;HW=3302"
address 10: master #2
address 15: slave #2, scanned "MF=Vaillant;ID=SCC00;SW=2200;HW=3903"
address 31: master #8, ebusd
address 36: slave #8, ebusd

thanks.

Address 3/8 is the Bulex ThemaCondens heater (same remark as @netweaver1970)
The ExaMaster is not recognized at all. This is expected as it is not in @john30 database.

I'm new to eBus, even after reading many hours about it.

Communication is present: ebusctl listen:
listen started

bai DateTime = nosignal;-:-:-;-.-.-;18.625
bai DateTime = nosignal;-:-:-;-.-.-;18.438
bai Status01 = 26.5;26.5;18.438;-;-;off
bai Status01 = 26.5;26.5;18.625;-;-;off
broadcast outsidetemp = 16.438
broadcast vdatetime = 23:08:00;27.08.2022
bai DateTime = nosignal;-:-:-;-.-.-;18.625
broadcast outsidetemp = 16.625

Even if not all messages are decyphered, the broadcast outsidetemperature is nice to have. (The thermometer is connected by wire to the Bulex ThemaCondens).
I started to integrate all systems into OpenHab. The bridge is communicating, but no outsidetemp is available (nothing after the automatic scanner) or manually added.

Is there anyone else with similar problems/configurations ?

After update of ebusd files:
ebusctl info:

version: ebusd 22.3.p20220508
update check: revision v22.3 available
device: /dev/ttyAMA0, enhanced
access: *
signal: acquired
symbol rate: 8
max symbol rate: 93
reconnects: 1
masters: 3

conditional: 3
poll: 0
update: 10
address 03: master #11
address 08: slave #11, scanned "MF=Vaillant;ID=BAI00;SW=0701;HW=3302", loaded "vaillant/bai.308523.inc", "vaillant/08.bai.csv"
address 10: master #2
address 15: slave #2, scanned "MF=Vaillant;ID=SBX00;SW=0326;HW=4802"
address 31: master #8, ebusd
address 36: slave #8, ebusd

Address 3/8 is still the Bulex ThemaCondens heater.
Address 10/15 is recognized. In reality it is the Examaster (Bulex).

I also flashed the ebus v3 pic with latest firmware.

I rebooted the system a few minutes ago.

in de log file there are a lot of the following messages:

Hi @DiaMontPhil
Did you ever find the right config? I have a similar setup (Bulex ThemaCondens + Examaster) and facing the same issues.

[DiaMontPhil]

Hi Bugzke,
I have not been able to spend time looking for a solution, but I have been thinking about it.
Maybe some day, I'll continue searching and will post my findings.

Hello
I didn't start yet but I have a Bulex Isotwin condens 25-30/B and a Bulex Mipro R Thermostat.

something i found in one of the pull request over here
john30/ebusd-configuration#436

Bulex is called Saunier Duval in other countries.
Saunier Duval MiPro Sense SRC 720 regulator looks like copy of Vaillant SensoComfort VRC 720.
Maybe the Bulex Mipro R can be a copy of the Vaillant VRC 700?
