T3E-PRO-V1.2 D121BBV flash ( openHASP )

Dirk2.0 · December 31, 2025, 9:10am

Hi,

I bought a T3E display without buttons. I was under the impression that I could flash OpenHASP (or something similar) onto it. There’s an explanation for this here: https://www.openhasp.com/0.7.0/hardware/golden-security/gs-t3e/. But before I hit flash, it seems to me that this device doesn’t have an ESP32 chip in it.

Next to both chips, there’s a JTAG connector to communicate with and possibly flash the device.

I suspect that the D121BBV is the CPU for rendering the GUI on the display, but I’m not sure.
Does anyone have experience with this, or is this something I can’t use?

By the way, Home Assistant detects the Zigbee device (without additional sensors), but I would of course like to configure the buttons on the display myself and have that handled through Home Assistant.

Type: T3E-PRO-V1.2
CPU: D121BBV
Zigbee: ZS3L

Firmware OpenHASP:

[edit]
For clarity: I purchased the Tuya T3E Pro Smart Control Panel Switch (Touch Screen Panel Switch, Zigbee, Intelligent Home Wall Push Light Switch, black ABS).
The price is currently higher than when I bought it.

This version is without ESP, and uses a D121BBV CPU.

This one? https://nl.aliexpress.com/item/1005009264062272.html?gatewayAdapt=glo2nld

Seems the only thing in common with the openhasp device you mention is the name…

Yes, and based on a tip that it would be the same as this device https://www.thesmarthomebook.com/2022/09/30/sonoff-cam-slim-and-the-nspanel-pro/

and this GS-T3E v1 - DISCONTINUED PRODUCT !!

The casing looks the same, but the print is slightly different. So apparently it’s a few euros cheaper, but without the ESP and I don’t think it’s usable

Oh, and because this post:

Hello @Dirk2.0,
Have you received the pro version by buying the non pro version on your link ?
I was about to buy exactly the same and I suspect them to send the pro version that seems not based on esp anymore …

I’ve been working on a configuration for the TS0601 by _TZE284_6ewhzbx4 in ZHA and created a config file called
tze284_6ewhzbx4_display_switch.py.

Current results:

Time sync works
Scene page 1 & 2: Home Mode / Away Mode / Party Mode / Full-off Mode (sync not applicable)
Switch (including internal relays): Chandelier / Downlight / Light Strip — synced
Dimmer switch page 1 & 2: all 4 — fully synced
Curtains: 1 / 2 / 3 / 4 — synced
Device: Scene 4-gang switch 1 / 2 / 3 / 4 — not full synced

The only thing I can’t get fully synced is the Device switch. When I change it in Home Assistant, the state does not update on the display. All other sliders and buttons do sync correctly

However, since I originally wanted to flash it with ESP firmware, and that turns out not to be possible, I decided not to use it.
