GREP commnad Reading through file Question

[notchy]

I have a need to read through the client list on my asus router RT-AC66U_B1 with Merlin Firmware Version:384.10_2

and if I find the MAC address I am searching for in the file location "/tmp/clientlist.json, I will execute a "CURL" command.

What I have, so far is this logic that i copied from another source. It is using the "wl assoclist" but I have a few AP's that my devices can be on and they will not show up with this command. That is why I want to read the "clientlist.json" with the current MAC addresses and if I find it I do some logic.

#!/bin/sh
# seconds between checks
WATCHDOG_SLEEP_SEC=2
# MAC Address 1
MAC_ADDRESS_1="[38:8B:59:2F:B5:XX]"
# MAC Address 2
MAC_ADDRESS_2="[08:78:08:3C:3E:XX]"
# Vera VSwitch 1 Device ID
VSWITCH_1="[457]"
# Vera VSwitch 2 Device ID
VSWITCH_2="[459]"

#This loop will check if a device is registered on the AP and send the on/off command to vera.

while sleep $WATCHDOG_SLEEP_SEC
do
if wl assoclist | grep -Fq $MAC_ADDRESS_1
then
    #echo Device 1 user is in
    curl "http://192.168.1.XXX:3480/data_request?id=action&output_format=xml&DeviceNum=457&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=1"
else
    #echo Device 1 user is out
    curl "http://192.168.1.XXX:3480/data_request?id=action&output_format=xml&DeviceNum=457&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=0"
fi

if wl assoclist | grep -Fq $MAC_ADDRESS_2
then
    curl "http://192.168.1.XXX:3480/data_request?id=action&output_format=xml&DeviceNum=458&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=1"
else
    curl "http://192.168.1.XXX:3480/data_request?id=action&output_format=xml&DeviceNum=458&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=0"
fi

done

Try:

if grep -q "$MAC_ADDRESS_1" /tmp/clientlist.json
