[john30]

did you issue a scan already (i.e. "ebusctl scan", wait a minute, then "ebusctl scan result")? Does it reveal the device ID?

[ronan-fontenay]

Unfortunately no :

root@orangepizero:~# ebusctl scan result
done

But this might help :

root@orangepizero:~# sudo ebusd --scanconfig -f --receivetimeout 50000

The device is not answering, am I right ? Any solution to force to load a configuration file ?

[ronan-fontenay]

After a few tests, I have a issue on the RX function (ebusd to ebus network). In other words, I'm only able to read.

[john30]

ok, that explains the empty result. you should really get your TX path fixed, otherwise it'll be not much fun :-)

[minscof]

@ronan-fontenay , did you succeed in having TX fixed ?

[ronan-fontenay]

@minscof Nop but this was 100% hardware related. Since then, I've ordered a adapter from FHEM forum, when it'll be ready, I'll update this thread.

[ronan-fontenay]

It's a way better with the ebus adapter v2.0 :

Thanks !

@ronan-fontenay, did you succeed in controling your boiler. I have a saunier duval and an ebus controller, but I can only read information, not update them. I would like to know if you manage to update temperature, start/stop the boiler with the EC7 thermostat. Thanks for your answer

Hi, I also own a " ThemaPlus Condens 25" but miss the Exacontrol E7L , I am considering to build a reader using ardiuno, but apparently I'll need a working TX adapter , I am not sure I understand why ...

Witam. Czy udało Ci się rozwiązać problem? mam dokładnie ten sam problem. Proszę o info. Pozdrawiam
