ESP32-S3 remote – A new hardware dashboard built around an ESP32-S3 Super Mini adds a remote, always-on status display for Bambu Labs 3D printers, streaming live parameters over MQTT with TLS and surfacing them on a 1.54-inch 240×240 TFT screen.
Keeping tabs on a 3D printer usually means either leaning on Bambu Labs’ onboard display or using the company’s apps. But for anyone who wants a dedicated screen somewhere else in the room, [Keralots] has put together a remote status setup built specifically for Bambu Labs printers.
At the center of the project is an ESP32-S3 Super Mini paired with a 1.54-inch TFT display that runs at a 240 x 240 resolution.. The device connects to Bambu Labs printers using MQTT secured with TLS. then collects status data and turns it into a real-time dashboard.. Critical printer parameters are shown as arc gauges, while additional live stats are available for deeper checking.. If you prefer alerts over visuals alone, the build also supports buzzer notifications for what’s happening during a job.
The connection approach is designed to be flexible.. The dashboard can be used with just about any Bambu Labs printer that has a Bambu Cloud access token.. For some models. it’s also possible to connect through LAN Direct—though the project notes that Developer Mode may need to be enabled depending on the rig.
The shape of the system stays consistent across those connection options: once the device can pull status data—either through Bambu Cloud with an access token or through LAN Direct when Developer Mode is available—it converts that stream into the same on-screen dashboard with arc gauges. live stats. and optional buzzer alerts.
For makers who want to read printer “vital statistics” at a glance. the pitch is simple: the dashboard breaks out the fundamental numbers in a way that’s quicker to parse than the interface of Bambu’s official software.. The project also aligns with a broader pattern of similar builds being shared previously—especially among people using prints as motivation to create practical monitoring hardware..

So they made a screen to watch the printer… doesn’t Bambu already have like a whole app for that? Seems kinda pointless.
Wait, it says it brings monitoring offline. Like… the printer goes offline? Or the dashboard is offline? I’m confused but also I feel like this is gonna break when updates happen.
I saw “MQTT with TLS” and I’m like ok so it’s super secure right? But then it says “access token” and “Developer Mode” which sounds sketchy. Like why do I need developer mode just to see gauges??
Arc gauges on a tiny screen is cool I guess. But if it’s streaming live parameters over MQTT, wouldn’t that drain your Wi-Fi or cause lag? Also TFT screens always look kinda washed out to me. Still though, buzzer notifications sound like my kind of chaos when filament starts acting up.
