First off, before I dive into this I want to be clear that I consider this to be fairly advanced functionality that the average user will probably never use, and I’m not really expecting any effort to be put in to fix the issues I’ve come across (unless they’re my own issues by doing something wrong).
I have a number of Zooz ZEN26 and ZEN27 switches that I’m working through updating the firmware on. I also have a Zooz z wave stick and the Silicon Labs PC Controller software. I’ve obtained the firmware updates from Zooz’s support. I have the z wave stick successfully paired as a secondary controller and it’s state is listed as “ZWAVE_S2_ACCESS_CONTROL”.
I’ve come across 2 main issues while attempting to update firmware:
- Firmware updates fail to transmit (first packet of the update file never sends) when the switch is paired with SmartThings with the state of “ZWAVE_S2_FAILED”. This is probably to be expected, given it’s already a failed state, however the switches in this state function perfectly fine otherwise. I haven’t had enough motivation to re pair these switches to fix the S2 state in order to do the firmware update.
- Firmware updates apply successfully when the switch is paired with SmartThings with the state of “ZWAVE_S2_UNAUTHENTICATED”, however, after the update the switch will drop off the network and requires a factory reset to pair it again.
If anyone can point out something obvious that I’m doing wrong (other than being too lazy to bite the bullet and re pair the switches and re set up the associated Automations) I’d appreciate it. Otherwise, perhaps these details will shed a bit of light on the subject for others that attempt this.
