CTS700 - what is needed? about nilan HOT 25 OPEN

I'm definitely up for helping with what i can, but i will have limited time from christmas and untill mid january.
Currently i'm importing all registers from nilans documents for the CTS700. Of course i can't test everything as i don't have the geo model as mine is the Air9 with a air to water heatpump for centralheating. It's a limited amount of different registers for the GEO model.

Hi,

It's great that you are interested in this project! There are a lot of changes needed to the integration to accommodate cts700. If you are willing to help me with this endeavor I think we can succeed. I have never even seen a cts700 device so you will have to help me with testing, and give me detailed explinations with pictures etc. If needed. Remember that the integration should support all cts700 devices, not just your model/version.

I will start by writing up the registers. After that we will try to figure out how to saftely recognise your device through the integration.

When this is all done we can start adding functionality.

Please respond if you are up for this? I can not do this by myself.

Hi

I'm currently using a manual modbus over tcp configuration for my Nilan Compact P (CTS700). The package I've setup for my integrations is listed here - perhaps this could help?

Hi,

I'm at a bit of a loss here.

So I guess the older versions of Compact P use the manual found here https://symlink.dk/stuff/CTS700_MODBUS-rev%202.01.pdf

And the newer versions with Air and Geo support use the manual found in @Chrunchy link.

I'm not sure how to support both, I cannot seem to find a version register on the newer document.

Can you @Chrunchy test register 4632 if you can read the version number?

from nilan.

Hi,

i have Nilan CTS700 and looking for integration support. My version is 1.40.05.38 from 2015 and has not been updated since.
I have a client app i can login as Installer (uses MODBUS to connect to CTS700) version 1.4.139 from 1.4.2018.

I can connect to CTS700 via the app from my server, but if i use MODBUS tools (Modbus pool) it says read error when connecting to CTS700. Not sure if permission or something else, i need password to login as Installer, but should not need anything to go as User. The Nilan App just does not allow anything else as Installer.

I've installed your HACS code, but when connecting to Nilan says "Invalid Response from Device" which is expected as you probably check some version data in one of the registers.

Cheers

Hi. Unfortunately cts700 is not supported. I would like to add it, but it seems to be a mess to implement and I do not have access to one so debugging would be hard.

Hi @veista,

I've ended up purchasing an Elfin EW11A unit to integrate my Compact S pump, but struggle with finding both documentation (modbus registrars for compact S) as well as ready integrations.

If you could advise on what you'd need, I would be happy to at least try.

I believe Compact S is a cts602 device so your question is in the wrong place. You can open a discussion, if you need generic help. I can not help with your setup: Read previous issues for hints, follow the instructions on the front page and then we can add Compact S to the supported devices.

Hi @veista
I am also using @jakobmoll 's manuel modbud sensor config to interact with my Nilan Compact P Air 9 - CTS700.

Even though python is not my main language, I might be able to help testing and fixing stuff.
Right now, the plugin gives the following error when trying to connect

  File "/config/custom_components/nilan/config_flow.py", line 108, in async_step_tcp
    await async_validate_device(
  File "/config/custom_components/nilan/config_flow.py", line 67, in async_validate_device
    result.registers[0].to_bytes(2, "little", signed=False),
    ~~~~~~~~~~~~~~~~^^^
IndexError: list index out of range

But it could be a UnitID problem, because I can't see why it should be 30 as default. If its the same as slave, it should have been '1', but that doesn't work either.

Hi,

Cts700 works differently than cts602. I have some modifications to support cts700 in my code, but at the moment absolutely NO functionality has been implemented. I have slowly made it even theoretically possible to support cts700. Adding support will take time and I am a busy man.

Thanks for your understanding, I will report here once there is something to test.

from nilan.

okay, so its not just creating a registry mapping for cts700 like the one for 602?
Could you create a branch with you work until now?

from nilan.

There is no branch yet. There is no code yet. It is complicated to add since I have not originally thought about adding cts700.

Keep in mind that there is also two types of cts700 as I mentioned before in this issue. Both are completely different.

from nilan.

Hi, I have tried to setup CTS700 myself with OH Modbus integration, I’d like to ask if anybody knows which register to read containing the below info:

1. Compressor state: can be off, defrosting, hot water production, heating, cooling
2. Flag indicate if the supplementary eletrical heater for the water tank is running or not (the red dot on the display)
   Many thanks!

from nilan.

I know you havn't written that it was ready.

However, I would like to give the new 1.12.13b on my Nilan CompactP Air a try, but I just get "invalid response" with no further log in console, when I try to add the integration.

I fetch data using modbus plugin in HA using the same IP, port and device (1), so I know it answers, but could it give problems, what some processes are already communicating with it?

Please tell me, how I can help testing it?

from nilan.

Thanks for your enthusiasm. I will let you know when I need your help. It will take some time to get to that point.

Do you have the old or new cts700?

from nilan.

I have a CTS700 Touch.
Display Software Version: 09.06.45 (2017-07-08)
Print Software Version: 2.02.13.93 (2017-07-08)
I am very interested in a working connection to my Home Assistant and as such would like to offer my help as well!

from nilan.

I have finally started to create development tools for implementing cts700 devices.

It would be great help if owners of cts700 devices would dump all registers to a file with qmodmaster or equivalent accompanied with device information and a picture of the type plate.

Hello everyone, here is the yaml in a package of my Nilan Compct P Geo 6, which has already been working for a few weeks! Unfortunately, a few little things are still missing (for example: manual control of fan speed 1-4)
A small note: I have translated my yaml from German into English. There might have been mistakes

Thanks for sharing your config! Have you figured out how to control active cooling? Neither 3284 nor 5288 works for me, already tried to Google for years with no clue....

What do you mean? For example qmodmaster works on linux and is open source. You just need to compile it yourself.

Software is updated to latest version by Nilan last week

I will be happy to help with qmodmaster if someone can guide me.

What kind of guidance do you need? The software is pretty straight forward.

What I need is: 1. dump of all register contents. This can be tedious. 2. A picture of the device type plate. 3. A clear correlation between register in modbus and function in HMI
