I want to link a Tradfri dimmable transformator to Homey. The device is in the list in my Homey app but it does not connect. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/f/0ffecc7e4c9fbf63434a47c679ca69bdd7ef9316.jpeg) The transformer works together with this remote. The remote I can connect to Homey. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/4/44fa6af1b65631ef2edb18dd4f68422efa0de13a.jpeg) I want to be able to control the lights with voice (Google assistent) And flows. This together with the remote. What do I do wrong? ---

I followed the steps Homey proposes to link new apparatus. With the remote it works, with the transfo nothing happens ---

Does the request time out? Did you reset the driver? Are you using the experimental v5 firmware? ---

No time out, no reaction at all. Screen of connecting stays on the question to switch off/on the drive. What experimental firmware? ---

Did you reset the driver by sticking a pin in the reset hole (shown in your photo)? Which firmware version are you running (in the Homey mobile app, go to “More \> Settings \> General / Meer \> Instellingen \> Algemeen” and look at the “Homey version/versie”)? Since you say that “The remote I can connect to Homey”, it should be the experimental v5 firmware because earlier versions of the firmware couldn’t pair with that particular remote. ---

I did use the reset hole with a pin. App 5.0.0.557 ---

Ikea’s documentation says to have minimum one light connected to it when pairing. Not sure if that makes a difference. But at least then you will get a visual confirmation of a reset. I noticed that I sometimes needed a bit of a longer hold with the pin in the hole. And the toggle power 6 times _should_ do the trick. ---

I have the same problem. Brand new transformer. No connection. Even tried resetting (6x off and on). Any suggestions?
