Starting on Ebusd

[klona]

Hi John. Thanks a lot for your project, all the work done, for shating that and support it. It's a huge work.

I found your project and decided to fully manage (under Jeedom) my boiler Saunier Duval ThemaPlus Condens F25 A (aka AWB ThermoElegance Advance 25-A or Bulex Thema CONDENS F25A ..) I add an ebus to Opentherm board in the boiler ( link to spare parts , if this can help someone : http://www.klima-parts.nl/awb-opentherm-module-0020092426.html )

As first step, I build a device using infos from http://otgw.tclcode.com/ and it's working with the otmonitor from this site. I set up a Raspberry Pi 3, connecting through USB to my Opentherm gateway. I get basic stuff working like starting heating but, as expected, it's a blackbox and I cant go further to manage all proprietary codes from Saunier-Duval. 08:17:40.498170 R80190000 Read-Data Boiler water temperature: 0.00 08:17:40.616808 B40191F80 Read-Ack Boiler water temperature: 31.50 08:17:41.524167 R10015A00 Write-Data Control setpoint: 90.00 08:17:41.715804 BD0015A00 Write-Ack Control setpoint: 90.00 08:17:42.550179 R80380000 Read-Data DHW setpoint: 0.00 08:17:42.668690 B4038FFFF Read-Ack DHW setpoint: -0.00 08:17:43.576196 R80000100 Read-Data Status: 00000001 00000000 08:17:43.694802 B40000100 Read-Ack Status: 00000001 00000000 08:17:44.602316 R80000100 Read-Data Status: 00000001 00000000 08:17:44.720933 B40000100 Read-Ack Status: 00000001 00000000 08:17:45.626988 R00120000 Read-Data CH water pressure: 0.00 08:17:45.746855 BC0120099 Read-Ack CH water pressure: 0.60 08:17:46.652785 R80000100 Read-Data Status: 00000001 00000000 08:17:46.772784 B40000100 Read-Ack Status: 00000001 00000000 08:17:47.678903 R80190000 Read-Data Boiler water temperature: 0.00 08:17:47.798786 B40191F80 Read-Ack Boiler water temperature: 31.50 08:17:48.704907 R10015A00 Write-Data Control setpoint: 90.00 08:17:48.823521 BD0015A00 Write-Ack Control setpoint: 90.00 08:17:49.731020 R80000100 Read-Data Status: 00000001 00000000 08:17:49.849627 B40000100 Read-Ack Status: 00000001 00000000 08:17:50.757009 R00110000 Read-Data Relative modulation level: 0.00 08:17:50.875628 BC0110000 Read-Ack Relative modulation level: 0.00 08:17:51.783004 R80000100 Read-Data Status: 00000001 00000000 08:17:51.901596 B40000100 Read-Ack Status: 00000001 00000000 08:17:52.807829 R801C0000 Read-Data Return water temperature: 0.00 08:17:52.926463 B401C2080 Read-Ack Return water temperature: 32.50

Then , as hardware is working, I moved to Ebusd. After some readings and tries, I get it to the point I can see some raw data.

pi@raspberry:/etc/ebusd $ ebusctl info version: ebusd 3.2.v3.2 signal: acquired symbol rate: 6 max symbol rate: 6 reconnects: 0 masters: 1 messages: 286 conditional: 0 poll: 0 update: 4 address 31: master #8, ebusd address 36: slave #8, ebusd

pi@raspberry:/etc/ebusd $ ebusctl scan empty

And now, I am lost... As far as I understand I should have something more detected on the bus (the boiler...) I guess it's because my boiler is not at all supported yet, but I can understand the next step . Can you point me in right direction ?

Thanks in Advance, /Klona

@klona did you actually install the configuration files? For Saunier see https://github.com/john30/ebusd-configuration/issues/77 fo one of the related investigative issues.

this does not look like valid eBUS protocol data at all. Are you sure that the interface transfers the eBUS data as is?

[klona]

Humm. Damned. I think you are right. I didnt realize that this hardware is doing opentherm on PIC and there is some sort of advanced commands through the serial management..

I think i will buy a eBus Koppler USB from Esera. Is that a fully compatible choice ?

EDIT : In fact, I am stupid.. I try your software on native ebus on an Opentherm gateway.. I need to sleep more...

Thx for the link. Didnt see this one and it will clearly help me
