Hi,

I have a device on KNX that is giving me the Energy usage in KW or Watts.  
I can see it in the ETS. But when I want to get it in Homey and choose for power than nothing happens.  
It seems like homey does not read this sensor.

Has anyone luck with this ?

Not yet from my side ☹  
I opened a case here [Support | Homey](https://homey.app/en-us/support/)

I think it could be a mismatch between data types. I’m using Power(W) in ETS and the KNX plugin for Homey is probably expecting something else.

I have a workaround for this if you have a NAS, Raspberry Pi or anything else that can run Docker.

With the help of knx2mqtt you can communicate with KNX.  
[https://hub.docker.com/r/krambox/knx2mqtt/](https://hub.docker.com/r/krambox/knx2mqtt/)

On Homey I have been using MQTT Client, HTTP request flowcards(for parsing JSON), Better Logic and Virtual Devices.

Hi, Looks good, but a bit to difficult for me 🙂

Hope Homey can come up with a solution @Klash
