Hi, thanks for the questions.
At the moment, MiraPlay AiO doesn’t support funscript-only playback (script without a video loaded in the app).
This feature is planned for the update after the upcoming Wi-Fi (UDP) connection update. We’ll announce it in the MiraPlay thread and on Discord once the schedule is confirmed.
For now on PC: you can use MultiFunPlayer (MFP) to play funscripts only, with the video running on another device.
Buttplug / Intiface are not supported. MiraBot uses TCode (multi-axis), which is structurally different from Buttplug (mainly single-axis toys).
Appreciate the question and the patience — more updates coming soon.
