self hosted.

I’ve e-mailed the developer of the app, but haven’t got a reply.

Update:  
I’ve checked the code and I think I’ve found it.

Root cause:  
In lib/helper/LocalIp.ts:11-14:

`ip = await homey.cloud.getLocalAddress();`  
`// Homey adds a port, so remove that`  
`// Old implement was always removing the last three characters, so keep using that for now`  
`ip = ip.slice(0, -3);`

The code assumes getLocalAddress() returns an IP with a 2-digit port (like :80), so it removes the last 3 characters. However, Homey self-hosted uses port 4860 (and 4859), so getLocalAddress() returns 192.168.2.170:4860. Removing 3 characters leaves 192.168.2.170:4 instead of 192.168.2.170.

This corrupted IP is then used in:

- lib/util.js:4044 for Gen2+ websocket config: ws://${homey\_ip}:6113/
- lib/util.js:4018 for Gen1 CoIoT config: coiot\_peer=${homey\_ip} (which should append :5683)

Additionally, the check in drivers/device.js:160 keeps re-corrupting manually fixed URLs. It checks if the current server URL contains homey\_ip (the corrupted 192.168.2.170:4). Since a correct URL like ws://192.168.2.170:6113/ doesn’t contain :4, the code thinks the URL is wrong and “fixes” it back to the malformed version.

Suggested fix:  
Replace the naive slice(0, -3) with proper port removal:

`ip = await homey.cloud.getLocalAddress();`  
`// Homey adds a port, so remove that`  
`const lastColon = ip.lastIndexOf(‘:’);`  
`if (lastColon !== -1) {`  
`ip = ip.substring(0, lastColon);`  
`}`

This correctly handles any port length.

I will mail this info again to the developer, maybe he reads this forum.
