Zigbee2MQTT setup - 502 Bad Gateway

Configuration Zigbee
,
1

Hi,

Sort of a newbie to this all. So I have replaced my Sonoff dongle with a SLZB-06M (I was using ZHA Zigbee integration before) I wanted to start to use Zigbee2MQTT but unable to get it working. I get a 502 Bad Gateway error. I removed any old data I could (or so I hope). I installed MQTT and Zigbee2MQTT and followed this guy’s link for setup.

https://thebloody.cloud/posts/Installing-Zigbee2MQTT/

I’ve tried this at least twice and checked my configuration but not sure what I am missing?

I looked up the zigbee-herdsman failure (that was in the log) but not finding a fix that seems to work for me. I am getting a host failure. I’ve doublechecked my configuration, but can’t seem to find anythign that looks out of place when compared to what the link I used for setup of Zigbee2MQTT article mentioned. Anyone have any ideas?? I know I am new to Zigbee2MQTT so maybe I’m missing something obvious, but can’t seem to narrow it down! Is it some legacy config info for my old Sonoff that coudl be doing it? I did delete any old reference to it in my config file (or so I believe).

Did you try a total reboot of the host?
Check also your coordinator, the address and port match the one you configured?

Yes, looks like your old one is already in the new config, check all the settings or start from scratch:

I guess you removed the old one from the host, right?

And remember to stop the addon before making changes to the config.

Thanks for pointing that out - I’m trying to dig now thru HA and check where I can remove it from. I did go into hardware, and yes indeed, it’s still showing as a connected device though I’ve physically removed it and deleted any addons related to it. I didn’t find anything in my config.yaml referring to it, and checking my zigbee folder (via file editor) and seeing if I can find any entries. Checking any of my VM settings as well (running HA via virtual on Virtualbox

Have you looked at the dashboard for the SLZB-06? There is a config editor built in.

Hi,

Yeah, I did use that to help configure Zigbee2MQTT and the configuration yaml does reflect that configuration

This is my SLZB-06 config. I have an extra M that I can use to compare settings.

Is the adapter discovered in Integrations?

Yes, it is detected in integrations and I do have it added. I do currently have my devices (initially I have the motion sensors [aqara] added via ZHA. Do you think maybe if I delete all the devices, remove the Zigbee integration and then try-readding maybe it should wipe out any orphaned entries pointing to the now retired Sonoff?

I think that is a logical step because HA is seeing the device. Check this out…

Deleting the state.json file in the Z2M folder fixed the conflict for most folks.

There is a port conflict as @mcarty mentioned earlier and based on the error log it still looking for the USB device.

{“path”:“/dev/ttyUSB0”,“manufacturer”:“Itead”,“serialNumber”:“a6f6f0ae8a38ef1196dd357af3d9b1e5”,“pnpId”:“usb-Itead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_V2_a6f6f0ae8a38ef1196dd357af3d9b1e5-if00-port0”,“vendorId”:“10c4”,“productId”:“ea60”} => ember: 4

Ensure ZHA isn’t installed and I’d start from scratch with Z2M. I’d suggest verifying the Z2M folder doesn’t exist after the uninstall.

thanks for the helpful info. I did in fact delete everything (the slzb-06m integration, zigbee integration, and deleted the entire zigbee2mqtt folder as well (didn’t find a json file in there interesting enough) and then started from scratch. Same thing: 502 Bad Gateway. I even went into my VM settings → USB, and removed any mention of the sonoff under there. Rebooted twice, and still getting the same error. This is really strange! The retired Sonoff must still be referenced somewhere, but for the life of me, I can’t seem to find it anywhere I look :frowning:

ZHA is uninstalled, correct?

Look through that list of installed devices and services. If you do see it listed. Then delete it and restart your HA instance afterwards.

Your photo shows it is installed

ZHA and Z2M can’t run on the same coordinator. It creates a port conflict.

You are a godsend my friend!! Thank you :slight_smile: So it looks like ZHA was still enabled. I did go in and delete everything per the article you linked to (I don’t know why that one hadn’t come up in my search earlier regarding 502 Bad Gateway error, but that one was SO helpful or got me on the right path (I hadn’t previously removed the zigbee.db as I wasn’t sure if it was needed to be, but once I removed everything including that, and then rebooted, and then started from scratch (ignoring the ZHA integration that prompted to be added in integration) and setup the SLZB-06M from scratch and followed the article I previously referred to everything worked flawlessly! Thanks again, I’m happy to finally have it working - just now need to add on re-adding those zigbee devices that were in ZHA before.

I am happy to assist knowing how frustrating ZigBee installs can be.

If you can, please take the time to mark my previous post as the Solution.

That will ensure this thread is closed out and more importantly, useful to other users who encounter similar issues.

on a side note….Welcome to the HA community!

The error log in your first post literally links you to this.
Point 4 of that page tells you to make sure ZHA is disabled.

You could have fixed your issue in 5 minutes if you’d taken the time to read the error on the screen & pasted the link in the logs.
