Hi all. I’ve just submitted an app with Homey support for Nilan Air.
I’m the owner of a Nilan Compact P - Air9 heat-pump.
With LAN-connected and network settings configured, I am now able with this app to get data from the device into Homey. Communication is local-network based and using ModBus communication.
The journey getting data from the Nilan Compact P has been very challenging (and time-consuming) and this topic we can share information/troubleshooting.
The CTS-7000 controller is installed in my Nilan Air. Using ModBus all kind of different documents and addressing spaces searched to get the version/state of which the app is in now.
Looking forward to your constructive feedback.
Before using this App, please make sure the LAN/network settings are working as intended.
I’m new to the Homey universe and have a Homey Pro 2023 and also a Nilan Comfort 300LR with CTS602 and Nilan Lan Gateway.
I tried your APP to see if it could connect and get some kind of data, and it seems like I get some readings but not sure if they are correct at any point.
Is it possible that you would share your code with me, so I can try to modify it to fit the Comfort 300LR, without starting from scratch.
I have the exact same config as you (Niels) have, but get a connection error. The Nilan LAN app works fine, and Homey finds the Nilan Comfort but no data coming through and in the app it says connection error. So clearly IP/Port/ID is wrong. I have identified the IP adress from the router, but that is different from the one Homey setup automatically. How did you get Data from your Comfort 300L?
I do not have a Nilan Gateway, I was told my product is not compatible with this. So did some digging myself. There is a lot of version/controllers and also different manuels/guides.
With my device connected to lan and I visit the ip in the browser (with http://), I get the folllowing:
I have CTS602 controller, it is not connected to LAN. I quess, via this modbus it is possible. I wanna my unit Nilan VPL 15 integrate to Homey. Any user experiences via your Homey App?
I dont know if (or how) your device is supported. Maybe some options are available with your controller and this app - or not. No guarantees.
In my case, with my device, a lan output was located inside the cabinet and with operator passcode, I was able to set network settings to match my network and then communicate.
Also cant Connect to my compact P AiR 9. The initial connection worked but then it says “no connection” in homey. I can’t understand why it’s not working, both the compact P and homey are on the same vlan so they should see each other. When I ping the Nilan it doesn’t respond. I am connected to the nilan gateway which in return is connect to the modbus. Any help or thoughts would be much appreciated!
Hey Kim,
Thanks for your swift reply. When I enter the ip address there is no response and no web page like you show. I could send Nilan a support ticket perhaps? But maybe the protocol for the gateway that I have is different? Since the Nilan app is working and I can control the heat pump with it I assume that the modbus connection is working. Orrr should there be a separate modbus connection into my lan?
Hello Kim,
Thanks for your app for Nilan.
I have a Nilan Compact P XL and have trying for a long time to read the data.
Was hoping that Homey community would eventually make an app.
It works just fine!
Initially I just had to change the IP address in the display of the unit back and forth - then the connection was ok and data being read.
Very nice!
Thanks
Would it be possible to add a “when” for outside temperature?
Making decision on the outside temperature makes sense to me - if under 5C I would turn on my air-supply pre-heater to save electricity in the unit (it turns on the compressor to heat air, when supply temperature is below setpoint)
