Description
The problem
Description:
After the automatic firmware update to version 1.1.2_b, it is no longer possible to control my EZ1-M device from APsystems.
Details:
Device: EZ1-M by APsystems
Firmware version: 1.1.2_b
Serial number: E070000009266
Issue: Control via automations, scenes, and scripts is no longer functional.
Current behavior:
Since the update, no active automations, scenes, or scripts are shown in the interface. Adding new ones appears possible, but they do not take effect.
External control (e.g., via Home Assistant or API) also seems to be non-functional.
Observed behavior:
No error messages on the UI
Logbook only shows standard messages (“OK”, “no problem detected”)
Control commands have no effect
Suspected cause:
It seems likely that firmware version 1.1.2_b disabled or blocked the control functionality or relevant interfaces.
Question to the community / developers:
Are there any known changes introduced with firmware 1.1.2_b that affect device control?
Is there a fix or rollback option available?
Thanks in advance for your support!
