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:
