GS-T3E v2.4 - Home Assistant integration fails to load — KeyError and "restart HA" error

[fabiogfabio]

After successfully flashing openHASP v0.7.0-rc12 (May 23 2024) on a GS-T3E v2.4 panel (no USB port, UART only), I was able to connect the device to my Wi-Fi and it correctly publishes MQTT messages. Home Assistant detects the plate via MQTT, but the openHASP integration fails to load.

When I try to add the plate via the openHASP integration (installed through HACS, version 0.7.0 or 0.7.6), I get this error in the UI:

“Configuration created for plate. The integration cannot be loaded, try restarting Home Assistant.”

Restarting HA doesn't resolve the issue.

Error log

Here’s the relevant error in home-assistant.log:

python
Error calling entry remove callback plate for openhasp
File "/config/custom_components/openhasp/init.py", line 296, in async_remove_entry
KeyError: 'openhasp'
This error repeats if I try to remove/re-add the plate.

Additional context
Board: Golden Security GS-T3E v2.4, ESP32, 16MB flash, no USB (requires UART flasher)

Firmware flashed: openHASP 0.7.0-rc12 cd34d89, environment: gs-t3e_16MB

I found no official documentation for the v2.4 variant of this GS-T3E board.

MQTT works fine — I’ve manually configured a button (e.g., p0b4) and successfully toggle a Home Assistant switch using MQTT automation.

The plate publishes state topics like:
hasp/plate/state/p0b4 = {"event":"up","val":0}

Feature request or fix?
It looks like there's either a bug in how the integration registers the plate, or a missing key that assumes something is already populated in hass.data[DOMAIN][CONF_PLATE][plate]. Would be great if this could be fixed or documented.

Let me know if I can provide more logs or test fixes!
