I need to update the firmware in my Zen26 and Zen27 switches. I was given a link to a page that has directions however I am unable to find out how to change the driver to Z-Wave Firmware Updater. When I look at the list of drivers this driver does not show in the list.

You need to install the Updater driver manually. Located here: [image] [RELEASE] Z-Wave Firmware Updater Custom Apps and Drivers Hubitat OTA Z-Wave Firmware Updater [584828d8cef1014c0b5e49ee] The firmware updater is in the form of a driver. It is a uti…

Also, please be aware that firmware updates have factory reset every single Zooz switch I have (Zen21, Zen22, Zen27, Zen30). If you do not want your automations to break or run into massive zwave network issues, I strongly recommend you follow these steps: Replace each Zooz switch (whose firmware…

Will the switch need to be replaced in each automation one by one? That sounds very tedious if it's the case

[image] mraz.camren: Will the switch need to be replaced in each automation one by one? Yup. There is no "global" way to do it. The key point though is preventing the creation of a stranded z-wave device. At worst, corrupted automations can be deleted and re-created, which really isn't that…

I installed the Z-wave firmware updater and started to update the firmware. It is now over an hour and the status shows: "firmwareUpdateProgress: Complete device is flashing..." and the currentFirmwareVersion still shows 2.1 when I am installing 3.0. It has been over an hour. Any thoughts as to th…

It's done and has factory reset. If you change drivers back to the original, you'll find that you cannot control the switch. So proceed with step 3 from the instructions above.

[image] aaiyar: stranded z-wave devices can really cripple a z-wave network I know you've mentioned this issue before. How do you tell if there are any stranded devices? I have some z-wave (not plus) locks that are misbehaving and I wonder if this is the issue.

[image] danfox52: How do you tell if there are any stranded devices? No easy way unless you have a secondary z-wave controller (like PC controller or z-wave toolbox). Then you'll start seeing nodes on the secondary contorller that don't show up in your list of z-wave devices (on the Hubitat). …

I followed step 3 by excluding the device then removing the device. Now I cannot add it back, when I try to add it back HE does not find the switch.

Try this first: Do a shutdown and then disconnect power from the HE for 30s. Power it up again and then try pairing. If that doesn’t work, bring the HE close to the switch and try pairing. I had to do that for a Zen30 recently.
