Firmware update for Leviton DZPA1 outlet switch?

I noticed in Zwavejs2Mqtt that I have a variance in the firmware on my DZPA1 devices (0.5 vs. 1.20).

I know Zwavejs2Mqtt can perform a firmware update, but I can’t find the firmware update anywhere so far. Anyone accomplished this or know where to find it?

Download link is here. You should be able to upload the DZPA1_01_20_ota__TargetZwave__.exe file to z2m.

Thanks! I’ll try that out this evening.

Well, that failed. :frowning:

I used the exact file you specified.

No idea then, I don’t have the devices. If no one else responds, you can ask for help at node-zwave-js discussions, they might be able to figure out how to extract the firmware, or provide a fix to support that file format. It seems similar to the Aeotec exe upgrades, which are supported.

Or you can try to use the updater tool itself. I’m not familiar with how it works.

I got the same error. Did you ever figure this out?

You can contact Leviton support and try to get the actual firmware files (*.ota) as other users have had success doing, or possibly wait for that exe format to be supported.

Firmware update instructions and OTA files can be found here:
