[RELEASE] Z-Wave Firmware Updater

Just updated 3 of my Inovelli dimmers painlessly. Working on 4th now. This is truly awesome. Thanks and great work @bcopeland

Bryan,

I've attempted updating devices that were within 10 feet of my Hubitat Elevation after successfully performing a Z-Wave repair. I would think that the routing should have been correct and signal strength good, but I am new to Z-Wave so maybe I'm missing something.

I did just successfully update one of the 8 Inovelli Red Series Dimmers and noticed something different about the successful attempt vs. the unsuccessful attempts.

The successful attempt had firmwareFragmentSize set to 40, while all of the unsuccessful attempts had it set to 46. Could this be the problem?

I live in an 2-storey townhouse. I've seen z-wave packets go from upstairs to downstairs and back upstairs rather than just go across an open room. So physical proximity doesn't mean they're taking a direct route.

I don't know what the solution is. What I would do is unpair each switch; bring the HE close to it and pair it again, and then try the firmware update.

It’s possible.. But the fragment size is mostly decided by the device.. depending on the command class version..

It’s also possible as @aaiyar pointed out that it’s the mesh routing. You may want to try a z-wave repair and then attempt it again..

If that doesn’t work, I’ll make a debug version that will force the fragment size smaller for you to try

Bryan,

I'm having some trouble with a Zen21 switch.

deviceType: 45329
inClusters: 0x5E,0x86,0x72,0x5A,0x73,0x85,0x59,0x25,0x27,0x20,0x70
firmwareVersion: 20.16
deviceId: 7708
manufacturer: 634

I suspect I'm trying to go a bridge too far in firmware versions. Zooz gave mew what I think i8s 2.26 : (ZEN21_V304_slave_enhanced_232_OTA_ZW050x_US_WD_027a_b111_1e1c_304_20200226.otz)

And If I read the above correctly, I'm running 2.16.

Every time I try to load it, I get the Sleepy Device message and the update just halts.

Suggestions? @aaiyar I know you updated some of these, any tips?

Thanks!
Scott

aaiyar · May 9, 2020, 8:38pm

Sorry, pretty worthless here. None of mine had that issue.

bcopeland · May 9, 2020, 8:39pm

Going to need logs

NotTheHerbie · May 9, 2020, 8:44pm

Thanks @aaiyar. I've seen similar behavior with my mesh WiFi network. I was hoping the repair would produce an optimized route. (FYI, the only LZW31-SN to be successfully updated of the 8 I've attempted is the one that is physically farthest from the HE. Go figure.)

Thanks Bryan. All of the devices are the same model with the same current version number (1.35) reported. Shouldn't the max fragment size be the same for each of them or is it dynamically calculated by each device?

Thanks,
Mike

scottgu3 · May 9, 2020, 8:50pm

I can probably do that.

I'm flashing a Zen27 at the moment, and everything is peachy. I presume you'll want me to switch on Debug logging in the Updater?

Scott

scottgu3 · May 9, 2020, 8:51pm

Thanks Ashok. Given you didn't mention any difficulties other than the Exclude thing, I figured that was the case! Thanks for confirming though!

Scott

bcopeland · May 9, 2020, 9:39pm

The device (depending on command class version) will request a fragment size

bcopeland · May 9, 2020, 9:39pm

No need.. It should show in the normal log

NotTheHerbie · May 9, 2020, 9:58pm

Okay. The same device version with the same firmware should request the same fragment size then, correct?

I saw in your code that it looks like if the device does not return a fragment size, it is defaulted to 40. All of the failed attempts for the other Dimmers always showed a fragment size of 46. The only one that succeeded reported a size of 40. Any suggestions on what I should try next?

Thanks,
Mike

bcopeland · May 9, 2020, 9:59pm

In theory

Correct.. On earlier command class versions this was not requested by the device

bcopeland · May 9, 2020, 10:00pm

I can throw up a debugger version that forces fragment size of 40

bcopeland · May 9, 2020, 10:04pm

@NotTheHerbie

This version forces the fragment size of 40 bytes

Gotcha. I'll probably mess with it tomorrow.

Scott

NotTheHerbie · May 9, 2020, 11:28pm

Thanks Bryan!

Unfortunately, I have not had any luck yet. I've tried four different devices with the same results. I think I'm going to try using the method Inovelli published to see if I have any better luck.

Thanks again for all your help. I've only had my HE for two months, but the more I explore this community, the more I'm convinced I made the right HA platform choice.

Best community ever!

I noticed the same with one of my Inovelli Reds: firmware flash would fail due to device being sleepy. I noticed that switch was also using frame size 46 instead of 40.

Checked my switch preferences and noticed that it was paired with secure z-wave. Excluded the switch, re-included it as non-secure, and it flashed perfectly with the expected 40 frame size.

Is your switch paired as secure?
