An important event that your SmartHome should be able to react to is the occupant's presence status. For example, you can switch off lights when they are absent or switch on radiators when they are present.
If you happen to still have a FritzBox, this presence detection is particularly easy.<\/p>\n\n\n\n

All you need is a FritzBox, NodeRed and the MAC address(es) of the resident smartphones.<\/p>\n\n\n\n

How to implement presence detection with the FritzBox in NodeRed is described in the following article.<\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>

<\/strong>To be able to use this configuration, NodeRed should of course already be installed.
How to prepare a RaspberryPi and then install NodeRed on it is described in the following articles.<\/p>\n\n\n\n

Log into the NodeRed configuration interface<\/h2>\r\n

Before you can edit your NodeRed configuration, you must - if activated - first log into the NodeRed configuration interface.<\/p>\r\n

\"\"<\/a>
View of the login dialog. Here you have to enter the login data that you specified during the configuration of the login. You can find information about this in the article NodeRed - set up user login<\/strong><\/em><\/a>.<\/figcaption><\/figure>\n\n\n\n
\n\n\n\n

Install FritzBox node<\/h2>\n\n\n\n

To enable NodeRed to communicate with your FritzBox you have to install the node \"node-red-contrib-fritz\". How to install nodes is described in the article NodeRed \u2013 Install new nodes<\/a><\/em> <\/strong>described.<\/p>\n\n\n\n

\n\n\n\n

Enter FritzBox node configuration<\/h2>\n\n\n\n

So that the FritzBox node you have just installed can also communicate with your FritzBox, you must enter your FritzBox login data in the node configuration.<\/p>\n\n\n\n

\"\"<\/a>
To do this, click on the \"Fritz!Box Callmonitor\" node. A new window will open in which you can select \"Add new fritzbox-config\" from the drop-down list in the \"Device\" line. Select this and then click on the pencil icon to the right of it.<\/figcaption><\/figure>\n\n\n\n
\"\"<\/a>
In the window that now opens, you must enter the login data for your FritzBox. First enter the name so that the configuration does not remain nameless and then the user name and password. If the FritzBox is in your private network, you can leave the details for Host as they are. Only if you are accessing a remote FritzBox do you have to enter the URL to the FritzBox here. Then you should also make sure that this connection is encrypted via HTTPS. in this case you must also check the box \"Is SSL connection\". once you have entered everything, confirm this by clicking on \"Add\".<\/figcaption><\/figure>\n\n\n\n
\"\"<\/a>
This will take you back to the previous window. The New FritzBox configuration is now already selected. You only need to confirm the window by clicking on \"Done\".<\/figcaption><\/figure>\n\n\n\n

Node code for presence detection<\/h2>\n\n\n\n

Presence detection via the FritzBox basically works by checking which smartphones are logged into the FritzBox's Wi-Fi or network.<\/p>\n\n\n\n

First you have to insert the node code listed below into your NodeRed configuration.
Then you need the MAC addresses of the smartphones whose presence you want to detect. You must then enter this in the configuration of the Fritz!<\/p>\n\n\n\n

It is important that you update the MAC address entered in the FritzBox node after importing the NodeCode. This should of course correspond to the device whose presence you want to monitor. How you can find out the MAC address(es) of devices in your network is described in the article Display\/find out the IP address of the devices in the network<\/strong><\/a> mentioned.<\/em><\/p>\n\n\n\n

Set a fixed MAC address for the smartphone<\/h2>\n\n\n\n
Some smartphone manufacturers have now started to randomly change the MAC addresses of their devices. This is a security feature so that your smartphone cannot be tracked in potentially unfamiliar WLANs.<\/p>\n\n\n\n
In our case, however, it is a hindrance as we identify the smartphones by the fixed MAC address. You should therefore deactivate this function for your Wi-Fi.<\/p>\n\n\n\n
