Making progress. Currently warnings from sections and acutators are discovered and organized in devices and entities.

Warnings as problem entities:
Next step is zones and zone errors before I go for the climate entities.
Hi
Any idea on how to connect it if not using a USB into home assistant. (Don’t want the HA in that location for example)
Would it be possible to have a esp8266 board or something pulling the data from the modbus and connecting via wifi to the HA server ? Loos like there is a modbus controller component in esphome.
I think it is possible. But there is no support for climate entity so quite some thinking is needed if you want to control the thermostats.
Also note that the modbus cable is a single twisted pair and it can be very long.
Hmm, ok thanks. My HA is virtual and in a different building 
Guess i will have to do it with a remote home assistant then when there is some raspberry pies in stock someware.
I’m using modbus over Ethernet via an USR-DR302 Din Rail Serial RS485 to Ethernet TCP IP Server Module which has been working really well.
Do you think this would work as well? Serial Port Rs485 To Wifi Device Server Module Converter Elfin-ew11a-0 Modbus Protocol Data Transfer Via Wifi
Sure, it’s the same principle. For me the DIN rail mounted Ethernet version suited my needs. As long as you get “Modbus over network” you’ll be fine.
Hi!
Thanks for great instructions. I have connected my esp32 with max485 modbus successfully to LK ICS. I can read out all temperatures etc but is struggeling with binary values.
@astrandb Do you know how to handle the adresses differently between the modbus registers listed in sheet “Input Registers” vs “Inputs”? I am trying to read out
1:01004 Zone 1 Heat Status 0 1 0 - No Heating In Zone, 1 - Heating Active.
which is listed in the LK “Inputs” sheet. But address 1004 is also listed in LK “Input Registers” sheet as:
3:01004 Zone 1 Battery Level 0 100 %
In your example here: GitHub - astrandb/lk-systems-floor: How to setup Home Assistant with modbus integration for LK Systems ICS.2 (Thanks btw! )
you do not seem to handle them differently?
In my setup i expose input as binary sensor with input_type=discrete_input and input register as a sensor with input_type=input
Thanks! Yes, I learned more about the modbus protocol now and the trick in esphome is to set:
register_type: discrete_input
for the binary sensors reading from modbus discrete inputs (format 1nnnn)
I found some good info here: Standard Modbus Data Address Format
For those of you using Node-red, here is a first devel release of my flow. GitHub - a-n-lundgren/nodered-flow-lk-modbus: Node-red flow to interact with LK ICS.2 Room Temperature Control System from LK Systems using modbus
Some wiring help would be appreciated. The LK box has a three-prong plug (+, -, 0) whereas the server I got off Amazon (https://www.amazon.de/dp/B08Q5H8DFY?psc=1&ref=ppx_yo2ov_dt_b_product_details) has four pins…
This should work:
A = +
B = -
0 = GND
I have the same dongle as @astrandb but get no response from the system. I have plugged it into my computer and trys with all kindes of settings in a modbus pc program but it timesout without answer every time. Its like the modbus comunication from the LK system is not activated. Anyone know what can be the problem?

I just got the modbus integration to LK ICS.2 working.
I used the LilyGo T-CAN485 board and ESPHome.
I haven’t tested it fully yet and I’m sure there are a few mistakes.
There is plenty room for improvement. I haven’t added any write registers for example.
Here is the yaml for esphome:

I’m finally also up and running and I got my first room conencted and possible to control via home assistant. However I struggle somewhat with the logic around the addresses. I got the following set up, is there someone here who could kindly give me a hint of how the address numbering works? More specifically, I’m trying to reach the address of a slave unit.
I’m not sure what you mean by master and slave units. But if you just got a single LK ICS.2 controller unit with thermostats in each room. The thermostats only communicate with the controller unit and you only communicate with the controller unit via modbus.
So each room would be address 1001 for zone 1, 1101 for zone 2, 1201 for zone 3 and so on.
I have put my updated code for the Lilygo T-CAN485 on github btw if anyone is interested.
First I want to say nice work.
How do you have it setup in HA?
Has anyone tried to connect HA to the LK Webserver instead of RS485 on the ICS.2 controller ? I have the LK master ICS.2 and webserver located in a very inconvenient place so running a new cable from my NUC to that place would be a mess so really hoping there is a way to get the LK system into HA through the webserver. Anyone tried this or working on it, pleased let me know.
