OpenHab 2 and Stiebel Eltron

Math · September 18, 2017, 1:34pm

Hi Guys

I have a running openHAB2 system and gladly stumbled upon the LWZ binding (great work!)
Unfortunately I have a LWZ 303 with firmware V.2.36 and therefore I geht the following error in the openhab.log:

2017-09-18 15:16:40.150 [ERROR] [tpump.handler.stiebelheatpumpHandler] - Thingtype version of heatpump 2.06 is not the same as the heatpump version 2.36

Formerly I used a FHEM installation which didn’t support V.2.36 either and I adapted the parser to my version. But I have no clue how this could be done in OH2

How can I change the LWZ binding to accept a V.2.36 system? I think I could also live with V.2.04 and I only want to read data
Is there a way to see the RAW serial communication date to and from the LWZ? (log?)

TIA

Matthias

Hi Math,

i you enable debugging for OH2 - or at least for the binding - in the logs you’ll get a more verbose information.
For more details - and how to include a different protocol version look here.

I thinkPeter will implement a V.2.36 binding version in not time

Hi Hogan

Thanks for your answer.

i you enable debugging for OH2 - or at least for the binding - in the logs you’ll get a more verbose information.

I already tried this but as there is no ongoing communication because of the incompatible version, the log file stays empty
I think the binding is “frozen” when an incompatible version is detected.

Therefore I’ll need some help to include my protocol V2.36 (maybe Peter will see my post)

Hi Hogan,

I have a 4.04 with Version 5.39 – but I’m struggeling at a starting point: Of course I have found the binding (for openhab 1) at github. I even looked in the openhab-addons-legacy-2.4.0.kar – where do I find the .jar file for the stiebel eltron binding? Or did I missed an importing point?

Cheers
Henning

Hi there,

did someone manage to get this work in openhab2 ?
I have a THZ404eco and I’m very interested in that

best regards,
Stefan

Hi,

I’m also looking for this, trying to connect my LWZ 303 version 4.09. Currently using FHEM, which has a very good implementation for the Stiebel heat pump, but migrating to OpenHAB 2.
I’m using the internal USB port (which is just a serial to USB converter integrated with the LWZ’s main board).
Could someone point out where I can find the jar file to be able to test this?

Best regards
Jens

I will get a tecalor TTL25AC heatpump (rebranded Stiebel Eltron) including the Internet Gateway installed in May. When reading through this post, I am not clear if the binding does actually support the gateway (ethernet connection) of the heatpump.
Related question: wouldn’t it be an option to use the modbus binding here?

I run my Isg with Modbus binding

Works so far good. But Stiebel has quite some buggy registers in the isg with wrong or no values.
Don’t know how they could ever ask for money for something like this.

The main functions do work

@shorty707
This is great!! Do you only read values from the heatpump or do you also write commands and control it via Openhab?
Would you be willing to send me the config file entries of your installation? That could save me a lot of work and trial and error.

Please note this is

for a WPL17 …> Type WPM SYSTEM incl a FET remote control and Cooling Sensors
heatpump combos with ventilation (lüftungsintegralgerät) uses very different modbus registers and below thing files will maybe not work at all
I added many registers … not all of them are populated with values; just deactivate the channels / registes that dont work for you; there are also tons of buggy values in the ISG; e.g. currently with firmware 10.1.0 energy values (power consumption) does not work really (confirmed by stiebel)
yes this also uses write registers and you can update via openhab if the heatpump supports
SG ready must be activated and configured first when you want to use it via ISG Web UI

absolut prima !!

    My heatpump will be installed in early May. I

will report back when I start implementing the Openhab
integration.

thanks a lot.

Dries_V · April 9, 2020, 4:54pm

LWZ 504 over here, I see they changed the connection to an USB. Will try to find a cable online and see if I can help test! Let me know if I can help anybody one way or the other.

kreutzer_peter · May 1, 2020, 10:19am

hi all,

i reactivated my openhab and wanted to look back into the stiebel binding.
do we still have interests here in the community for such kind of binding?

Hogan · May 1, 2020, 6:03pm

Hi Peter,

i am totally interested in this binding. Would be extremly helpful to connect my LWZ directly to my openHABianPi

matzetronic · May 11, 2020, 5:41pm

Hi,

I’m totally interested. I have Robert Penz Heatpumpmonitor running on a Pi connected to my THZ303 integral. I want to move the thing to openhab2 to make use of alerts etc. Since I’m also a software engineer I could also help writing some code, but I have no openhab dev experience.

@shorty707
Got my first values from the heatpump (tecalor TTL25AC) into Openhab using the modbus binding. Initial test was “actual hot water temp” and “target hot water temp”. Both worked fine.
Having problems with getting actual outside temperature. The register you have in your thing-file seems to retrieve a different field. Will still need to do some further testing.

kreutzer_peter · May 11, 2020, 8:30pm

hi all,
i have now reworked many aspect to be able to get a potential pull request accepted.
my current version is available here.

i have asked Stefan to test and contributes his version of heatpump into my branch.

If this is done I will upload again a new jar file for testing in the community.

@shorty707 good to hear that the modbus binding works with the ISG.
The current binding does not require the ISG and can directly connected to the serial port of the heatpump.
