De Dietrich/Diematic (Modbus) to MQTT Interface

le_chat_qui_taff · November 5, 2024, 1:00pm

you are right, I thought this image was a front view of the boiler-side connector

Thx for the help

Hello,
I am so happy that I found this solution for getting my DeDietrich Boiler connected to HA.
DeDietrich is very rare in Germany and not so well documented.

In my case, I would need to connect through WIFI. Was anyone able to achieve this?

When I compare the configuration of the USR-TCP232-306 to the manuals of the PUSR WIFI models, there are quite some differences.

There is no dedicated Serial configuration section. Just something called WIFI-UART

image767×454 66.1 KB
I found nothing to set it up with work-mode TCP Server. They only mention work-modes are Transparent, Serial Command Mode, HTTPD Client Mode & Modbus TCP <=> Modbus RTU

Has anyone a suggestion how to get the Boiler connected via WIFI?

Many thanks in advance,

Sebastian

Hello,
After you fix wiring - is it working ?
Im asking because Im at your stage - USR-TC232-306 send message that boiler is offline. I did your wiring mistake, after that I did it correct, but status is the same. I`m with MC45 with Diematic 3 with two modbus connectors.
also I want to ask you about your wiring - white and black are A nd B. Brown and red are ? because I did not see them in original manual.

Bonjour Benoit, J'ai récupéré ton programme pour le transcrire en Arm64 et ad…apté les paramètres de configuration compatible avec mon matériel. Je possède une chaudière fioul De Dietrich (GT120) avec Diematic3 sur laquelle j'ai branché un convertisseur RS485 vers TCP par une liaison Wifi (PW11). Voir image de la config PW11 ci-dessous. ![image](https://user-images.githubusercontent.com/124525423/226195491-d9f4c008-5b3a-4456-9f43-47a20be10e1d.png) ![image](https://user-images.githubusercontent.com/124525423/226195551-16d471aa-41f4-4f4f-a0c1-0dee1106891c.png) J'ai installé ton programme via Docker Compose tel que tu le montre dans ton Wiki. Au lancement du programme le fichier log boucle sur les infos ci-dessous ([logs.txt](https://github.com/Benoit3/Diematic_to_MQTT/files/11011868/logs.txt)). ``` 2023-03-19 17:37:33,460 - Diematic - WARNING - Init Link with Regulator 2023-03-19 17:38:13,616 - Diematic - WARNING - Synchro timeout ``` Je reçois bien les publications sur mon serveur MQTT mais toutes les valeurs sont vide. ![image](https://user-images.githubusercontent.com/124525423/226196837-72b47bf4-ea14-45d3-9c29-db660aeef65d.png) J'ai testé la communication avec mon convertisseur et je récupère bien, manuellement, les valeurs de mon diematic en entrant une valeur de registre. J'ai effectué différent test et je suis dans une impasse, j'attend ton secours.

Bonjour Benoit,

thank you very much for guiding me to this. I will test it with the PW11 probably in december!

gbg78 · November 17, 2024, 7:40am

Hello,
First I wanna say that that your job is AWESOME! Thanks, thanks, thanks!!!

I manage to install all yesterday and it works fine for now.
I want to ask you is this normal and if it`s not… do you have idea how to fix it:

there is some difference in sensors - According to MC45 boiler power is 8 or 11, but in HA shows 39%. when oit goes to 20+ on Diematic panel, HA show 45-55%… How to caliberate HA to shows real power % ?
I cannot set target Temp from HA. it`s stays to 17.5 all the time. From Diematic III Panel I was set it to 24C day temp. If I change from 17.5 to 21 from HA… after 20-30sec boiler stops (temp is below current). If I change baclk to 24C, after 20-30sec boiler starts… As I see, I can control boiler, but in HA stays to 17.5 all time.

I don`t have Internal Temp Sensor (room temp) to circuit A for the moment. I will try to find and install some type temp probe these days (must see whitch will be compatible, If you have any suggestions it will be nice).

For info: I have only circuit A, I dont use for hot water, only for house heating.

BenoitS · November 17, 2024, 3:03pm

Hello,

after reading W630s model doc, it should work with it with following settings:
-serial server transparent mode
-packet time of 50ms , packet length of 256

I think somebody have already done it with this kind of material but I didn’t found any forum message to confirm it.
Benoit

BenoitS · November 17, 2024, 3:19pm

Hello,

Power is (to fast ?) extrapolated from fan speed when Ionisation current is above 0 here (Diematic.py / line 359) :
self.burnerPower=round((self.registers[DDREGISTER.FAN_SPEED] / FAN_SPEED_MAX)*100) if (self.ionizationCurrent>0) else 0;

Values can vary depending boiler. You can adapt FAN_SPEED_MAX.

For Zone A settings, they shoudn’t be displayed without Internal Sensor. Have you enable the force circuit A flag in the conf file? I don’t understand what behaviour could be waited from temp setting if you do not have internal temp sensor.

Regards,
Benoit

PS: the interface has been done with reverse engineering and testing on one kind of boiler (MC25), so it’s difficult to coer the wide range.

gbg78 · November 17, 2024, 8:48pm

I Did not know that, will try to calibrate is to show correct power value. As I see its exact 25% difference (when its idle, HA report 25% power).

No, I did not enable this flag. I folow your manual and I did not see such thing/manual.
I totally new in this… HA control over MC45 is from 24 hours… for the moment looks very cool - this gave me all that I can need.
Last week I realized that I dont have internal Temp sensor... I ask why is installed like this 15 years ago... No reasonable explanation. It works, but maybe not optimal. Now Im searching for Temp probe/sensor that is compatible with MC45 boiler/Diematic III. Do you know is there any specs for that sensor ?

After your explanation about power %… My only issue is Day/Night temp in HA… it`s always 17.5C (you can see on my screenshot in previous post). Today, just before leave the house I change from HA from 24C day temp to 21C and 5min ago when I go to Boiler for last check it was set correct to 21C… But in HA is still 17.5C…

Also want to ask you - do you know why I have “mode zone A” - unknown status ?

As new User I cannot reply again (some limitation up to 3), so here is update:

I found here FM52 room control with temp sensor and just install it.
All problems disapiar at once!
Power/load is reported correctly !
I have internal room temperature
I can see Mode Zone A status
I can see what Temp i set now for day and night
I can see pump power (I really dont know how this is related to this room thermostat/control…)

So, sorry for my previous stupid questions and thanks again for your great work here.
I decide to tipe for update, because some of my ussues dont look to be related to this internal control that I was miss and I want to give info for other users to avoid my problems and mistakes.

Thomas_VDB · December 11, 2024, 12:38pm

Hi all,

I have succesfully implemented the Modbus communication to my De Dietrich boiler (Innovens MCA 15/25), using home assistant.
Everything is working fine for a few years.

However lately I have seen that the boiler restarts itself multiple times a day. There is no alarm logged in the alarmhistory (most recent alarm is from 2023). The water pressure is okay (1.7 bar) and I cannot see any reason why the boiler would restart itself.
I have made a small movie, where you can see on the display that the boiler suddenly restarts.

I would like to contact a technician, but they will surely start replacing boards and other stuff, without first knowing the root cause.
I couldn’t find any other forum with so much knowledge about De Dietrich. So I was hoping that anyone had some ideas, advice?

Home Assistant is polling the boiler very slow (I’ve slowed it down to 1 request per minute). However that doesn’t seem to help.

Thanks!
Thomas.

PawelP · December 11, 2024, 1:08pm

Hi Thomas,
Not sure if anybody can help in this forum but wish you luck in solving the issue

Does the boiler restart or it just loosing the connection with the controller? Do you hear that boiler stops and starts again?

In my Modulens G when I restart the boiler it takes few minutes it works again as the boiler starts the ventilation procedure every time (code M20). I can’t see similar behaviour in your movie, but maybe your boiler does not force the ventilation procedure. Did you try to restart it manually and see if the boiler starting procedure is different to what you recorded?

Regards,
Pawel

Thomas_VDB · December 11, 2024, 3:08pm

Hi, thanks for your reply. There is most definitely a difference between a cold boot (me turning the mains off and on) and the ‘internal’ reboot that I am experiencing. When I do a cold reboot, the boiler starts indeed with te venting procedure. This doesn’t happen during an automatic restart. But during that automatic restart, I do hear each time that it (re)ignites the flame.

Thomas_VDB · December 13, 2024, 8:07am

anyone? pls.

elmr91 · January 11, 2025, 2:08pm

Hello,

Thanks to @BenoitS, I want to report another successful setup with HA integration.
Heater: HPI G Hybrid 200 ASL 8kW / Diematic4
(integrated Inverter 8 kW + gaz 25 + 200l ECS)
RS485 adapter : Eflin EW11 (very cheap ~10€, works very well)

For the time being, all basic info (boiler/zoneA/zoneB/water) are correctly reported to HA
I will dig now how to add more specific sensors (linked to inverter for example)

jimbim · January 13, 2025, 10:11am

Hello @BenoitS,

I have started my work on getting my DeDietrich Boiler connected to HA.
First of all, I noticed that the described way to create a HA Add-On from the WIKI does not work anymore.
I found a way how to build it and I will post, once I get it all working.

For the connection, I am using the Protoss PW11 RS485 to Wifi adapter.

Suprisingly, I worked like a dream after fireing up the HA Addon. I was able to read and control everything. However, after a while it stopped working.

Now, I am getting the “ModBus Master Slave Synchro Error” message all the time.

Maybe you can help sorting it out.

Below you can find an extract of the log:

Hi, I think a build of HA broke it. I fixed it by updating the Dockerfile as follows

tomik67 · January 16, 2025, 9:41am

Every now and then I get a message in the logs about a frame too long error, is there anything I can do about it?

Hi champ4210.
After applying your change I get the same message as before:

2025-01-16 11:48:34.210 ERROR (MainThread) [supervisor.docker.addon] Invalid build environment, can't build this add-on!

Have you encountered this before?.

jimbim · January 16, 2025, 11:47am

Becareful that the Dockerfile is named “Dockerfile” case sensitive and not “DockerFile”.

That did the trick for me.

tomik67 · January 16, 2025, 12:15pm

Brilliant!!!
I didn’t think of that, no one paid attention to it, the file with that name was original.

Now I’m stuck on.:
The command '/bin/ash -o pipefail -c pip install pytz' returned a non-zero code: 127
Changing to pip3 doesn’t help
