Phone presence instead of geofencing

[vincentcox]

It would be nice if it can set the status to away if certain devices are absent in the network. I don't like geofencing because it drains the battery.

Following code is an example if 2 devices are present or not:

# Function to check for the presence of two MAC addresses in the network
check_mac_addresses() {
    # Arguments: Two MAC addresses to check
    local mac1="$1"
    local mac2="$2"

    # Run arp-scan to detect all MAC addresses in the network
    # Adjust the network range as per your configuration
    local mac_addresses
    mac_addresses=$(arp-scan --localnet | awk '{print $2}')

    # Check if both MAC addresses are in the output
    if echo "$mac_addresses" | grep -iq "$mac1" && echo "$mac_addresses" | grep -iq "$mac2"; then
        return 0  # True: Both MAC addresses found
    else
        return 1  # False: At least one MAC address not found
    fi
}

# Example usage
if check_mac_addresses "aa:bb:cc:dd:ee:ff" "11:22:33:44:55:66"; then
    echo "Both MAC addresses are present."
else
    echo "One or both MAC addresses are missing."
fi 

Is that something that fits the project?

@vincentcox, since the only device I have running 24/7 is my router (running openwrt) I adapted Silviu's amazing script to run there and implemented your phone presence idea.
I used a built-in tool instead of arp-scan but it works really well.

Hi guys,
Unfortunately, the last period was a little busy for me.
@vincentcox thanks for the idea and for the 🍕 :) I will try to analyze and find the time to implement that.
@tbilou sounds interesting, maybe you can contribute to a separate branch with your implementation if not to the main with a cross-platform solution
Best,
Silviu
