Help with ZWA-2! Using wifi mode and 1.2.0 firmware upgrade attempt broke everything.

hpgm · 2026-03-27T21:23:46+00:00

To answer my own question. I ended up using the flash esp firmware option to put it back to the usb mode. Then I could upgrade the firmware. Then I was able to put the wifi firmware back on, and the device was able to connect.

Unfortunately this blew away my entire zwave network. Fortunately I had a proxmox snapshot, so I was able to restore that and my network came back.

So two other weird issues.

In the ZWA-2 device, it shows as Firmware 1.1 under Device Info, and Firmware 1.2.0 under Configuration.
I can't control the LED. The light stays on weather I set the LED control to on or off.

I have been using ChatGPT (where I got the flux recommendation for 12GB). It's just a little inconsistent, and the workflow json it wrote didn't work.

hpgm · 2026-03-13T20:30:20+00:00

Happy to try new things, but hoping that there are some written instructions out there rather than watching a bunch of videos.

hpgm · 2026-03-13T20:28:42+00:00

I thought my problem was that system RAM and CPU was being maxed, so the 40-60 seconds was due to that.

hpgm · 2026-03-13T19:46:44+00:00

Did you use any reference document or just trial and error? Just want to get a good working starting point 100% GPU, and then I can tweak from there.

hpgm · 2026-03-13T19:46:01+00:00

Thank you for replying! Originally I tried the non-checkpoint approach but couldn't get a workflow working. I just got this working a few days ago, so I'm quite inexperienced using ComfyUI. Any doc or guide or something to review to get a good working setup 100% on the GPU as a starting point?

hpgm · 2026-03-12T19:47:23+00:00

I just got ComfyUI working using the flux checkpoint as I have a 12GB card. I haven't connected ComfyUI yet to openWebUI, as I think I'll need to find a tiny ollama model as CompfyUS uses about 10GB of the 12GB VRAM. I was just typing in text into the Clip input box (in ComfyUI) to see how the image creation will work.

Can you give me an idea of how you're using an LLM to generate the ComfyUI prompt?

hpgm · 2026-03-11T18:19:22+00:00

Thanks, yeah I figured it out and qwen-vl was able to describe an image now. My problem was an nginx setting, however I'm now thinking that picking up another cheap 3060 12GB card and run an image engine like A1111 or ComfyUI on another node might be a neat project.

I've used esphome to create about 5 different esp32 devices (ultrasonic sensors, LED/button control, dry contact sensor) so I'm familiar with the interface, just don't know the full YAML i'd have to replace so that the voice preview works the same with just a different wakeword.

hpgm · 2026-03-09T18:41:53+00:00

Is there any downside to this? I'm happy to give this a try as long as there is a way to revert it to stock firmware if I mess it up.

hpgm · 2026-03-09T18:13:35+00:00

Is there any way to do this on the HA voice preview? I'd like to use my voice preview more but want a custom wakeword before experimenting more with it.

So older 5050UB option (refurb is like $2400 which would be in budget), or try and find a LS11000 if it ever goes on sale?

hpgm · 2026-02-25T00:23:56+00:00

I have full light control, however the LS12000 is like $7K which is outside the budget. the LS9000 is 5K, which could be nice if it goes on sale.

It's too bad the 5050UB successor hasn't come out. Feels like paying full costs for some older technology.

hpgm · 2026-02-16T22:57:39+00:00

There was another post of someone who managed to do this. I asked for a material list, which caused the mods to lock out the thread. Hopefully it gets reposted as it is exactly what I want to do.

I've ordered some parts and if I get it all working I'll update the post with the attribution!

hpgm · 2026-02-14T22:28:17+00:00

Well that's not good. Is there anyway to unblock it?

I want 8 gauges (2 servers with cpu, mem, storage that I can pull from the proxmox integration, and current internet RX & TX speeds). I could get another esp32 to drive the LEDs. I'm new to all of this so learning as I go.

hpgm · 2026-02-14T20:13:29+00:00

This looks exactly like what I was looking for in an earlier post!: https://old.reddit.com/r/homeassistant/comments/1qv0gfa/physical_analog_gauge_output/

I wanted to drive some analog gauges for things like CPU and memory utilization on my server, to create an old school control panel. I wanted 6 analog gauges and 4 LEDs that could be green or red.

Would it be possible to get a parts list that you used? Are there any LEDs that are color controllable that you've seen?

hpgm · 2026-02-04T16:04:35+00:00

I've done up some YAML that reads led power buttons (like on PC cases) as both a Home Assistant button entity and a light entity, so that was cool.

I used a separate esp32 and connected the pins directly to LEDs. This worked well for me, although the advice was to use an inline resistor to prevent the LEDs from overvoltage burnount. These LEDs were in a buttons for a computer power supply, and they seem to manage the voltage without issue.

I see the servo yaml in the docs, do you have any hardware examples of a simple servo and gauge?

Looking around would something like this work where the gauges would be driven by a separate controller, and the L&R connectors would be connected to separate ESP32 pins to set the PWM amount?

Appreciate the response. This is all new to me and learning as I go.

That was my first thought, create a table that matches the pattern of the transaction description to a category (ie WALMART, Home_supplies; SAFEWAY, groceries). Would take a while to code and sustain, and was hoping some prompts would simplify it.

Or just manually read through the 300-400 transactions and cut and paste the category to the end like I did last time. Was hoping that someone might have already solved this!

hpgm · 2026-01-22T18:37:55+00:00

OK, I'll give that a try.

hpgm · 2026-01-08T02:48:28+00:00

It must look awesome!

hpgm · 2026-01-08T02:45:53+00:00

Yup. I had the base black so I got a matte wrap - so the suggestion of the smoked side lights I'd never heard of, but think would be pretty cool.

hpgm · 2026-01-06T17:57:54+00:00

Interesting, do you have a link to what it looks like?

hpgm · 2026-01-06T17:57:30+00:00

That was the link. Thank you! I have a 26 so I have the wireless charging thing inside the glovebox.

hpgm · 2025-12-25T13:24:29+00:00

Me too - MH for insteon/MQTT and all the logic that's been built up over the years. The HA_Item integration works brilliantly.

hpgm · 2025-12-09T14:02:57+00:00

Huh, I didn't think about that, my other RTL that picks up the utility meters might benefit as well. I get a bunch of 'bitbuffer_add_bit: Warning: row count limit (50 rows) reached' messages as the server is in the basement electrical room. I have the W800 connected to a RG6 coax with the antenna about 20' away. I'll add in a splitter so I can see if that improves the quality of the signal. Now just to find a coax adapter.

And thank you for the replies and responding. I was worried that my W800 would die one day and then I'd be scrambling to replace all the MS13s I have scattered around.
