Common Issues / Frequently Asked Questions

  1. homebridge-fritz can't login to the FritzBox
Some users have reported that logging into the FritzBox internally via `https` fails. This seems to be caused by the FritzApp *occupying* the same port.
In this case you can connect internally via `http` or use the external IP.

`Fritz!Box platform login failed` messages can be caused by invalid login data or wrong url.

Log messages if the form of:

    { error: { [Error: self signed certificate] code: 'DEPTH_ZERO_SELF_SIGNED_CERT' }

indicate that there are SSL security problems- most likely due to self-signed certificates. Use the `"strictSSL": false` option to disable the respective check.
  1. homebridge-fritz is not able to update my thermostat
Current FritzBox firmwares seem to ignore API updates when the thermostat has been key-locked. 
No workaround available- please contact AVM to change this behaviour or don't use the locking mechanism.
  1. homebridge-fritz can login but not update thermostat battery charge
Battery charge is not an API function. That means that the user must have access to FritzBox administration, not only to the SmartHome API in order to use this functionality. 
Update your Fritz!Box user accordingly.
