I have a Homey, and just bought some Ikea Tradfri parts: E27 full color lamp, E14 dimmable lamp and power switch, and also a E1524 remote, so the basic remote version.
For some unknown reason this remote device is not supported in the Homey Ikea app.A rotating dimmer remote is supported however.
It would be very convenient to use the Ikea E1524 remote to control the Ikea lights, but also through flows control my KNX devices. One control for all. It is a fairly cheap remote and it is easy to add 1 or 2 to trigger flows.
So why is the standard remote not included in the Ikea app?
Is there a technical reason for it?
I believe it is a Homey app, who is responsible and maintains the app? What is the correct place to request new app features?
