Does your system have CTS700 or CTS602 control?
With CTS602 you can use the Nilan App.
With CTS700 you cannot - it only talks native modbus - I thinks this app is for CTS700 systems, as it works fine for my unit
I think you’re right. It’s a pity though, because I was thinking of running programs based energy price, like when energy price is negative to increase fan speed and cooling.
Hopefully some nifty homey developer will build something for my model 
. I think I saw some integrations for the 602 with home assistant.
Please note that outside temperature is not pushed with the trigger-event, you will need to read the given outside tempature from device capability. I’m sure you will figure it out 
New version pushed for verification (1.0.2). Please donate if you like the app.
Hi
I just purchased the homey pro to get access to the Nilan app
Iam the owner of a Nilan Combi polar 302. And the Nilan user app is working perfect. But I get: connection error
How do I find the right IP address?
I can also pay someone here to fix the connection between my Nilan, and Homey pro 
Hi Magnus, I am not aware of all models. In my case, I did connect the device with lan-cable and found the options in the menu. Maybe send a picture of your interface on the device itself.
You can also try and check your router, to see if the device is connected - dependening on your network configuration ofcourse.
When I did find the correct ip and default page was shown, when entering the ip in the address of a browser.
Please try that out and share your findings.
Hello Kim
I have plugged in the Nilan gateway with lan cable, and everything is working just fine with the Nilan user app.
Attached are pictures of the interface from the Nilan user app, and from the advanced setting in Homey.
How should I proceed here to fix the error in communication ?
Thanks for your help! 
Dear @Kim_Kokholm and @Tibor_Haraga,
CTS700 has an onboard RS485-TCP gateway, but CTS602 does not have such module. You don’t have to buy expensive gateway from Nilan, there are cheaper ones on the market (e.g. Elfin).
A comprehensive guide on how to wire and configure such a gateway for CTS602 can be found on my website.
You can find there a complete solution for Nilan machines. A QuickApp that can control almost everything in CTS602 or even CTS700 boards.

Hello,
I recently purchased a Nilan Compact P CTS700 and was wondering if you @Kim_Kokholm or @rolcsi.hu have a tutorial for setting up the remote connection for this specific model.
I also bought a USR-W630 Modbus TCP to Wi-Fi module and would like to integrate it with my system. I have the latest touch panel (pictured on the right), but I’d prefer to remotely control the system rather than relying on the built-in interface.
Would using the USR-W630 module with Home Assistant be the easiest way to achieve this? If anyone has experience with a similar setup, I’d love to hear your thoughts!
Any advice or recommendations would be greatly appreciated!
I have bought the USR-W630, but i am having trouble locating the ModBus on the Nilan Compact P CTS700
Does anyone know where to connect it?
Here is the USR-W630, and it is the RS385 i have to connect it to.
But i am not sure where on the other end.
There is both the spare “panel” RJ45 that isn’t connected to anything, and there’s the cable endpoint where the control panel is connected to.
At the top left, the Internet cable is split up and put into the 4 points.
But the USR-W630 only has 3 holes to put wires into for some reason.
Hi Niels,
Curious if you managed to get this to work as I have the same setup 
Cheers

Hi Kim,
Apologise for late answer.
I get the attached picture. Can’t find the site
Is there something to buy as an easy fix?
For my installation, the only experience I have, is that the url should display a welcome message.
Reasons you are not able to see the same:
- IP is incorrect
- Phone-/ and Nilan-network is not connected
- Other Nilan hardware than mine
Hi @Niels_Bakraie Did you manage to get the Nilan Comfort 300LR with CTS602 to work with Homey Pro. I’m strungling and cannot figure out whats wrong. I have the IP adress but cannot get a webpage when using the IP adress. I can ping it, but that’s it. The iOS app works just fine so it is connected. PS. I use Wifi and not a wired connection, maybe that’s why?
Hope somebody will share if they have succeeded
