I did one of these and several Zen21 switches. The firmware updated fine, but also reset the switches. If I were doing it again, here's what I would do:
- Replace the first switch in rules/apps with a placeholder virtual switch
- Update the firmware on the first switch
- When the update is complete, check if the switch is still paired to HE. If it is, all you need to do is replace the placeholder switch with the real switch. If it isn't, then:
- Exclude the switch
- Include the switch
- Replace the placeholder switch in rules with the newly included switch
- Proceed to the next switch
Edit: I didn't do step 4 and it messed up my z-wave network within a day. But when all is said and done, the firmware update was totally worth it. Thanks @bcopeland for providing this tool, and @agnes.zooz for the firmware files. Also thanks @bobbyD for helping me identify what I had done to mess up my z-wave network!
