 **Note**: Before using this agent, please make sure that the names of your smart home devices are compatible with CMK.
 CMK only allows `.-_a-zA-Z0-9`. If your devices do not follow this pattern, the agent replaces ` ` (space) with `_` and removes all other non-allowed characters from the host names.
 
 After installing the package, create a new WATO rule **Setup -> Other integrations -> Fritz!Box Smarthome devices**.
 Here you need at least the user name and password to log in to your Fritz!Box For the password, I recommend using the CMK password store. The agent uses HTTPS on port TCP/443 by default and checks the certificate of your Fritz!Box, so if you do not have a good certificate, activate the option `Ignore SSL errors`. Don't forget to use your Fritz!Box as a condition with **Explicit hosts**.
 
+**Note:** If you are also using the Fritz!Box agent with your Fritz1Box, you need to change in the CMK host settings of your Fritz!Box for _**Checkmk agent / API integrations**_ to _**Configured API integrations, no Checkmk agent**_
+
 By default, the agent uses the CMK piggyback mechanism for the Smarthome devices. Depending on your CMK edition, you therefore have two options for adding these hosts. In the _RAW_ edition, you create them like any other host object (by hand, CSV, API). Set the following fields:
 - IP address family -> No IP
 - Checkmk agent / API integrations -> No API integration, no Checkmk agent
