We likely would only be able to support Virtual Station on specific Android devices due to hardware requirements, but we'll definitely take a look! Currently we ask Virtual Station users to keep the app open rather than in the background, so unfortunately it does turn the spare device into a dedicated Wi-Fi Access Point stand-in. In your case, a Wi-Fi Access Point may be a better solution.
You can see our documentation for the API here: https://docs.candyhouse.co/ It will be open to Android users as well as soon as we finish implementing Wi-Fi Access Point support for the Android app. We currently only support calls made through the cloud, but we appreciate your suggestion and will be sure to mention it to our product development team.
Thanks for your feedback, we appreciate it! Hope you're enjoying your Sesame and don't hesitate to let us know if you have any further questions. - CANDY HOUSE
