Hey vlxne_god! Apologies for our delayed response. We know having your controllers in reach are an important part of making the experience easier to access, so we'd be glad to provide some insight.
At the moment, there currently is not a way to locate your lost controllers, we would recommend retracing your steps and seeing if it was left in a different room possibly.
With this being said, our engineers are always working towards expanding the VR experience for our users. We suggest posting this as an idea to our team who looks into features for future updates!
