iRT Bus Connection not working #10

tbergmair commented 3 years ago

Question I ordered a iRT Board that came today - flashed it with the latest bin 1.9.10 , got wifi running, connected it to my iRT Bus , set passive mode in Config, rebooted , telnet the device, set again to mode 4 , restart, set log j - then see the output

Screenshots [TELNET] Connected to IRT-ESP version 1.9.10.20110420. Type ? for commands. log j

Any suggestions what i can do ?

Hi Thomas,

Can you provide me with a little bit more information ? What boiler do you have ? What thermostat and how did you connect the interface board ?

Thanks,

Victor

tbergmair commented 3 years ago

Hi Viktor!

Thanks for reacting!

I did more research and test the last days with some progress

I got a Buderus GB112 with a MEC and a HW4201, i connected it now to ECO-BUS - Pin 2+3 ( as 1 seems to be ground), the Webinterface still says "EMS Bus is not connected." , if I telnet the device and write command "log j" i get now the following output :

Your heater looks pretty similar to the Nefit that we have. I took this picture from the manual I found online at: http://myskill.be/Buderus%20GB1%20technisch.PDF

The wires from the EMS-iRT board go to ports 3 and 4. For my set-up to work correctly I had to disconnect the bridge-wire on ports 1 and 2..

If I am correct, the MEC and HW4201 is your (wireless?) thermostat. You will not need these to operate the EMS-iRT board. Victor knows more about this than me, but in most cases the EMS-iRT board does not like to be sharing resources with old thermostats..

tbergmair commented 3 years ago

Hi ! the heater maybe ( i don't know the nefit) - but i connected it to the eco-bus on the HW4201 - the control unit of all! I tried also to remove the Roomthermostat MEC while testing - but it made no difference to the log output

tbergmair commented 3 years ago

if i would only connect the irt board on the heater it would be no use at all when i would therefor need to disconnect the HW4201 - as all the thermostats and pumps are connect to the HW4201

jperquin commented 3 years ago

Maybe share a schematic with the connections (incl port numbers) of all components? That may provide insight as to how these components (GB112, MEC, HW4201) interact..

Victor-Mo commented 3 years ago

@tbergmair I have done some research on your setup. The interface only works on the iRT bus between the boiler (GB112) and the control unit (HW4201). From what I could find the ECO-BUS is some sort of CAN bus ( https://github.com/flyingflo/logamatic ).

I did found the following connection diagram: HW4201_UBA

I think the best place to connect the interface is on the HW4201 on pins 1 and 2 of the UBA connection. But anywhere between the boiler and control unit is fine. But I do find it a very 'strange' how the boiler and the control unit are connected. Is this also how your setup is ? Or has it a different connection.

Your setup is very similar to the setup in issue #7 It might be a good source of information.

tbergmair commented 3 years ago

Hi Victor ! Yes - thats the way all is connected ! Did u see my posting from yesterday ? I connected it to Port 2 and 3 of the ECO-BUS - and at least sometimes I got some messages

I can try to connect it in parallel to the UBA Ports - but i CAN NOT disconnect the HW4201 from the Boiler as then NOTING would be working as all the Sensors and Pumps are connected to HW4201 !

Victor-Mo commented 3 years ago

Hi Thomas,

From what i could find on the internet I pieced together a picture of what I think is your setup: hw4201_mec_passive_4

I also include where the interface board should be connected.

tbergmair commented 3 years ago

many thanks - I will try that tomorrow !

tbergmair commented 3 years ago

I tried to connect it that way - but it didn't get any better - i only got "Error! Unable to read the iRT bus." - not even the messages i got on eco-bus in my post from 4days ago

Victor-Mo commented 3 years ago

Did the 'log j' show any output ? Did you try swapping the two wires to the interface board ?

tbergmair commented 3 years ago

yes- tried both !

i only get 👍 -> log j

System Logging set to Jabber mode

-> Error! Unable to read the iRT bus. Error! Unable to read the iRT bus.

when i connected it to eco-bus 2+3 i at least got :

Victor-Mo commented 3 years ago

I think the problem is the 'strange' way the controller is connected. Normally the thermostat is connected at points 3 and 4. When I can find sometime i will build a setup with the thermostat connected to 5 and 10 and see if I can detect a correct signal.

iamceph commented 3 years ago

Hey guys, I got the exact same problem. My boiler is Nefit EcomLine HR43. I connected the device to the 3 and 4, same as the thermostat is and I got the exat same output. Here is my log message: https://paste.gg/p/iamceph/79c45e6adbd54dc89bf17e57d8a582fa

I did not wanted to create another issue, if I should, just tell me. Thanks for your time! :)

jperquin commented 3 years ago

The Nefit Ekomline should work "right out the box".

A few things you might want to try:

iamceph commented 3 years ago

Thank you, will try

iamceph commented 3 years ago

The Nefit Ekomline should work "right out the box".

A few things you might want to try:

  • disconnect wire between ports 1 and 2.
  • disconnect regular thermostat in case you are running that in parellel.
  • change to settings 5(active with polling).

So I tried these steps and now it seems that communication is offline.
