Introducing ScriptO Studio
Posted: Wed Dec 24, 2025 6:47 am
Little did I know how far down the rabbit hole this whole Zombieverter, Openinverter thing would take me...
After making the hardware for Headless Zombie, I started on the difficult bit, the software, and frankly it grew out of control.
Finally got it converged though, and the result is ScriptO Studio, which is a PWA that talks to MicroPython over a webrepl.
It turns out that the ESP32 has enough horsepower, RAM and storage to run multiple projects at the same time!
Here's a video of it running an OVMS emulator, OpenInverter configurator and GVRET at the same time (yes it really is connected to my OVMS mobile app).
So you get not just a UI to configure OI and OVMS, manage the 4G modem and GPS and send metrics , but also have plenty of capacity left to run users scripts to do all the little bits of IFTTT that come up in all the variations of conversions we do. And because it supports
And on top of it it has a Cursor style agent interface for the editor, so you can just say 'when a Tesla Model S brake pedal is pressed, turn on the brake light', and you have the ScriptO to do that in seconds, from the AI provider of your choice (it even looks up the right CAN IDs for you)
In a way its a bit like Dave Fiddes' OI CAN tool, but the python code is running on the ESP32!
