This is possible. Tom Heine has made an app to do this with a TCP-modbus konverter (webpage in Norwegian): [Flexit Nordic S4/S3 og Homey – tomheine.net](https://tomheine.net/flexit-nordic-s4-og-homey/)  
To use this app you need CLI access to Homey Pro. That prosess is explained here: [Getting Started | Homey Apps SDK](https://apps.developer.homey.app/the-basics/getting-started)  
Is it not an ease process if you are not a developer. You need a PC or Mac with admin rights to do this.
