Hey guys,
I created an app for AppDaemon to bring full functionality to IKEA E1524/E1810 and IKEA E1743. If you have more than one controller you can add a new instance app and that’s it. I don’t support group of lights, just 1 sensor connected with 1 light. However, you can connect them by creating different apps with multiple lights and the same controller in all of them. You can see the post about it here.
