Failed to load integration for translation: Integration 'MQTT' not found.

Is it called something else?

#

Tried to disable it and reenable it went ok but still nothing... Restarted HA I don't see that same error in the log any more yet still it doesn't see it updating lock/unlock

#

Oh I just found this error
Log details (ERROR)
Logger: homeassistant.components.mqtt

The 'color_mode' option has been removed, please remove it from your configuration

#

not sure what color_mode is

#

I guess maybe look in the configuration files for something hiding

#

grep -rnw --include="*.yaml" --include="*.yml" 'color_mode' .

#

didn't seem to find anything

#

maybe I will update dev and hope for magic.

#

probably from a light entity coming from MQTT discovery

wooden island
#

I had an old light.yaml so I removed that and updated to beta 2025.8.3

#

the color log error went away before I removed the light.yaml

#

but still no mqtt updating rtl_433 sensor

#

Oh it's working now

Sweet now I need to connect this to my door lock

I guess just old dragons in the code some place.
