cannot get it to work after second install

[nilsmau]

Configuration
Add-on Version: 1.2.0
Installation method: Home Assistant OS
Core: 2026.5.3
Supervisor: 2026.05.0
Operating System: 17.3
Frontend: 20260429.4
All devices are in the same network.

Issue:
The integration aborts with "failed to set-up"
How did I get there:
I had removed the initial integration (it seemed to work) of the add-on and removed it via HACS b/c it only brought up one of my two Miele devices.
Rebooted HA and then reinstalled via HACS.
ever since then I get the same error (also after rebooting HA again)

This is the error log I get:

This error originated from a custom integration.

i have no clue what: "Check Settings → Devices & services → Discover devicesshows _mieleathome._tcp entries. " under trouble shooting means, its only leads me to home assistant's device list also that "Discover devices" I can't seem to find.

[tiehfood]

Most probably a mDNS problem, so HA can't see the Miele devices...
I will make the integration more robust against that, so it is at least "usable" but you won't get push events probably, if mDNS can't reach HA (because that's the way, endpoints are registered by the devices).

Could you verify, that HA receives the mDNS messages?

[tiehfood]

Please try version 1.4.0. The integration should at least load without error. But without mDNS you probably won't see devices or push events

[nilsmau]

@tiehfood, i have installed 1.4.0, still the same errors in the logs.
I now get "Failed setup, will retry: no Miele devices reachable on the LAN yet — will retry. Configure static IPs in the integration's options if your network blocks mDNS/multicast."
what I observe in Settings -> Network -> ZeroConf Browser: the mieleathome._tcp.local pops into existence and then disappears again. it repeats after a short while.

NB: I have tons of others for other services, no issues, e.g. Airplay devices, printers, etc

[tiehfood]

The device you see for a short time is the device the integration creates itself. So this is fine.
But it seems, that mDNS traffic from your Miele devices does not reach Home Assistant!
If they are on a different subnet, make sure you have something like avahi-daemon running on your router.
Unfortunately the integration does need mDNS, as I had no luck in creating the device subscriptions over IP.

this is the text-content I can access while its there.

[tiehfood]

Yes, that's fine. As I said, this is the device, Home Assistent itself creates. Not a real Miele device and this should be hidden from Integration.
I assume 192.168.2.101 is also the IP of your HA instance.
Your real Miele devices are not recognized. There must be a problem with mDNS

[nilsmau]

yes, ...101 is my HA instance. I made some inroads: the devices were not advertising themselves via mDNS. Only after power-off (unplug and plug back in) they announced themselves.
The integration picked them up indeed.

[nilsmau]

Now I am struggling with getting HA to interact with them but that:

[tiehfood]

Thanks for the detailed logs — both issues are fixed in the next release:

• Standby state crash: your dishwasher reports StandbyState=3 ("going to standby"), a transient state we hadn't mapped. It no longer crashes the sensor.
• Power switch 404: your G7191 blocks all DOP2 writes over the local API — so remote on/off isn't possible on this hardware (it's a firmware lock, not a bug in the integration). Instead of throwing an error, the integration now hides the power switch when the firmware blocks writes, and shows a clear message if a command is refused.
