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
-
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.
Hello,
Have a look here:

Bonjour Benoit,
thank you very much for guiding me to this. I will test it with the PW11 probably in december!
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.
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 didnât found any forum message to confirm it.

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 shoudnât be displayed without Internal Sensor. Have you enable the force circuit A flag in the conf file? I donât 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 itâs difficult to coer the wide range.
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 17.5CâŠ
Also want to ask you - do you know why I have âmode zone Aâ - unknown status ?
I will call tomorrow Boiler mechanic to ask him about water pump speed⊠As I see you have info in HA⊠on mine there is no info. Maybe pump is old or not so smart .
