I have an ESP8266 sending data from a moisture probe, been working fine for some time.
It is now throwing this error........

14:36:08

[W]

[component:170]

Component api cleared Warning flag

14:36:08

[W]

[api.connection:107]

: Reading failed: BAD_INDICATOR errno=11

14:36:08

[W]

[component:157]

Component api set Warning flag: unspecified

When I checked the yaml file i see this...

# Enable Home Assistant API

api:

I thought there was a key there before, any idea on where I would find the api key?

Thanks.

I'm supposed to respect my elders, but it's getting harder and harder for me to find one now.

Are you using this sensor with ESPHome?

You put the api key into each ESPHome device firmware, use the addon to find the editor.

# Enable Home Assistant API

api:

encryption:

key: "API key goes here"

But you also have to enter the same key so HA knows these messages are from ESPHome...... sorry, can't find where that is controlled right now.

In ESP Home, where it says show api key I get "Unable to automatically extract API key. It may not be set. Open the configuration and look for api:."

and in the config it just says

# Enable Home Assistant API

api:

Sorry, I can't for the life of me find the place where this is autogenerated in HA.

No worries, I had another ESP device so I copied the api from that and it worked, guess its not specific to the device.
Thanks for the replies.

Glad you got there.

AFAIK you're right, the API is common to all ESPHome devices. Accordingly, its defined in HA somewhere - but where?!

I am going to keep a copy, until I find where it's stored in HA 😀
