Ok, I was able to verify that firmware on the device was 1.40. The firmware I'm trying to put on is 1.50, so it is newer. However, after I did an update with interview on the device as was suggested in the thread, the information in Xray was now empty. The firmware info major and minor, plus pretty much the entire DH Commands sections were empty. Also my rules in eisy referring to that device said it was no longer available. I'm disappointed. I have a new Zwave stick coming. I think I will give up on ZWave OTA firmware updates in eisy and do firmware updates outside of eisy using Simplicity Studio. I know that works and is pretty straightforward. In this experience and for the Zooz ZSE42water sensors at least, eisy's ZWave OTA firmware update feature isn't ready. Updating firmware on devices inside of eisy should not be problematic and convoluted. For the moment, I regret attempting it.
