I thought I would post this for those looking to improve their experience with the Zooz ZSE50 Siren & Chime. I didn't see anything and didn't get alerted to it. This is my biggest gripe with this device where you add a file for playback and you have to adjust all rules to match the newly mixed up tone numbers. You can use the Device Firmware Updater app to get it transferred OTA. It takes forever to update so be patient.
Firmware – Version 1.20 (released 10/2025 as OTA)
Improved Tone File Management: Resolved the tone file ordering issue by introducing fixed, addressable locations for each tone. Adding or removing sound files will no longer alter the sequence of existing tones. This update ensures that scenes remain consistent and unchanged when new files are loaded.
Sadly this really doesn’t work well. I added a tone last night and it screwed up 75% of my tone numbers. I really wish Zooz would find a better way to manage the tones so that every time I touch a tone in the thing it would NOT change tone numbers.
I noticed that there is a 1.3 version, but I am unable to install it. After copying if to the hub and select Device firmware updater and then the ZSE50, the only option is V 1.20 and it can’t fing the v 1.3 file.
I was able to update to 1.30 which, of course, screwed up a few of the file numbers AGAIN! You have to choose the file to upgrade too…1.30 in your case, then upload it. The select the device: ZSE50. Choose the target: 1.20. The select the upgrade file: 1.30. It takes quite a while to upload to the device.
Where you click Upload. Then you choose the Device (Zooz Chime in my case) and it will show the current version if the device is online. As you can see, mine is already at 1.3, but yours will show 1.2 if it’s at that version.
Excellent description of the process, thanks. I was doing those steps exactly. I guess 10th time was the charm, as it finally showed the 1.3 firmware file. Strange, that was.
