Firmware VER 1.30 (released 06/2026 as OTA)
- Fixed a bug where the child input could become stuck in the ON state when parameter 5 = 10 and parameter 11 = 1. The issue occurred only while the relay was ON, even though keypress events from input wire changes were still being generated.
- Fixed a bug where the device stopped reporting relay and input states to the controller after a power loss in a garage door opener configuration (relay + door sensor). The ZEN58 continued to accept commands, but status reports were no longer transmitted.
