I tried to turn on debug on default hassio level ā¦ got trylion of lines 
but when searched for string fao got plenty of those:

of course real data hidden behind XXXXX
I havenāt found anything for string āopenweatherā¦ā or error which I could connect in any manner to fao sensor.
Further, openweathermap_key string in this debug log I found only in lines provided above.
Maybe this is a hint somehow ?
another thing Iāve found in log:
2020-04-12 22:23:55 WARNING (MainThread) [homeassistant.helpers.service] Unable to find services.yaml for the wb_irrigation integration
2020-04-12 22:23:55 WARNING (MainThread) [homeassistant.helpers.service] Unable to find services.yaml for the variable integration
but those are just warnings not errors ā¦
other logs but seems nothing special ā¦
2020-04-12 22:23:58 DEBUG (SyncWorker_5) [homeassistant.util.json] JSON file not found: /config/custom_components/wb_irrigation/.translations/en.json

sic! ā¦ I must be doing something wrong here 
for sure this is some super silly mistake but where ā¦
