Please remove [flash]

My frontend reports I have an extra key [flash] that will be a breaking change soon. Only thing is, I search for it, and the only place I can find a reference to it is in the @OttoWinter ESPHOME addon, which, if I may say, is just about the greatest thing since sliced bread.

Is it just my bad config, or will this be solved somehow by itself (someone else way smarter than me : )

Thanks!

What is the exact message? There is usually a line number.

flash could also be related to lights

All it says is:

Your configuration contains extra keys that the platform does not support.
Please remove [flash].

And I have none of those “effect: flash” in my lights…

Do you have any auto discovered mqtt devices?

try looking in the actual homeassistant.log file. there may be more helpful information in there.

I have the same error:

2019-03-21 19:59:12 WARNING (MainThread) [homeassistant.helpers.config_validation] Your configuration contains extra keys that the platform does not support.
Please remove [flash]. 

Searching all my config files only brought it up as a comment (# before it)

Do you have any auto discovered mqtt devices?

I have one ESPhome device still running on MQTT as I haven’t yet switched it over to the api

Take a look at the home assistant discovery topics.

mosquitto_sub (your login and host stuff) -t homeassistant/# 

It might be a retained discovery message.

And the geniouses strike again! You were absolutely right. I went into terminal and found the mosquitto.db, stopped mosquitto and deleted the file. restarted Home Assistant and - Gone! Thank you so much all who cares to help!

where do you find the mosquitto.db file?

It’s hard to find with hass.io but if you delete the broker it deleted the dB as well then add the broker back. Or use MQTT explorer…

I have hass.io install with docker via @dale3h’s script on USB stick, so mine was here:

/usr/share/hassio/addons/data/core_mosquitto

Great script by the way : )
