Enbrighten ZW4002 Fan Controller Firmware 5.51

HA Configuration:
Home Assistant Blue / Hardkernel ODROID-N2/N2+
Core: 2025.10.3
Z-Wave: usb-Nabu_Casa_ZWA-2_80B54EE233F8-if00

HA was showing a Firmware update available (5.51) for my 2 Enbrighten Z-Wave 3-Speed Fan Controller Wall Switches. One of the new features is an adjustable LED parameter. I ran the updates and performed a re-interview. The new LED parameter showed up and is functional.
However, HA is now showing the installed firmware as 0.51 and is again showing an available update to 5.51. I reran the firmware update again but it has just repeated the same indication as having 0.51 installed.
I’m not sure where the problem lies so I’m just starting with raising it here.

I am having the same issue as well.

Same here. I found somewhere online to try pushing the top paddle 3 times, followed by the bottom paddle 3 times…but this did not help. I am going to try using the power cut tab and ā€˜restart’ the controller before attempting the firmware update again.

I’m having the same issue with mine. One of them locks up and I have to re-power the switch. None of them are updating. While observing the update I noticed the percentage would get to 88 percent or so and the window would just vanish. A few moments later it would show back up as needing the update. I decided to use Simplicity this morning and attempt to diagnose and possibly update. I’m just not finding a happy way to do this.

Functionality remains ok as of this morning.

I just noticed that Simplicity reports ā€œOTA Firmware Initialization failedā€ when checking for new firmware.

I’m going to put it back in the controller and let the HA gurus figure this out.

same issue here. also no luck after trying a manual update from this file firmware/zwave/Enbrighten-GE/ZW4002/55258 - In-Wall Fan Speed Control, 500S/5.51 at main Ā· jascoproducts/firmware Ā· GitHub

Im guessing its the actual firmware and not HA related, bug reported here [Bug Report]: Enbrighten - ZW4002 - 55258 - 5.51 Ā· Issue #137 Ā· jascoproducts/firmware Ā· GitHub and here [Bug Report]: Enbrighten-GE - ZW 4002 - 55258 - FW 5.51 Ā· Issue #138 Ā· jascoproducts/firmware Ā· GitHub

sounds like they just forgot to update the version to 5.51 from the 0.51 beta. same code. Release 5.51 for Enbrighten 55258 by steverep Ā· Pull Request #216 Ā· zwave-js/firmware-updates Ā· GitHub

I observed the same behavior, so started poking around and found this thread.

Has anyone reported the issue to Jasco / Enbrighten?

@bobbeims, as @devWaves posted right above you, it has been reported on their GitHub: [Bug Report]: Enbrighten - ZW4002 - 55258 - 5.51 Ā· Issue #137 Ā· jascoproducts/firmware Ā· GitHub
