Home Assistant removes sensitive values from several messages that can end up in troubleshooting logs. Xiaomi router login failures stop recording the supplied username and password, and a failed Start.ca setup stops repeating the configured API key.
The National Weather Service integration also stops recording the coordinates of a followed person or device when it updates the weather station for that location. FinTS banking messages drop account numbers and the online-banking username while retaining the configured bank name.
Franck Nijhof’s corrections remove these particular exposures; they do not make every log free of private information. FinTS can still include an account number when it forms part of an entity’s existing name.
