curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$return = curl_exec($ch);
curl_close($ch);

echos the single DS18B20 on your linux system as a REST string. if you have two, see my other gists
<?php
$command = "find /sys/bus/w1/devices -name '28-*'";
$path = exec($command);
$fullpath = $path . "/w1_slave";
$filename1 = $fullpath;
$handle1 = fopen($filename1, "r") or die("Unable to open file!");
$myString1 = fread($handle1,filesize($filename1));
fclose($handle1);
$tempC1 = ((float) substr($myString1, strpos($myString1,"t=")+2))/1000;
$tempF1 = ($tempC1*(9.0 / 5.0)) + 32.0;

is the ac running based on if the temperature is rising or falling
import homeassistant.remote as remote
import time
import math
import sys
def updateState(previous,current):
settings = {"device_class": "cold", "friendly_name": "Is the AC Running"}
if previous.state != current.state and math.fabs(float(previous.state)-float(current.state)) > .2: #if the absolute value delta is between 0 and 0.2 then we don't want to update the state to prevent false positives
if previous.state > current.state: #air temp is falling
print(":: ",current.state,"AC is running")

Quick script to echo the CPU temperature in F and C of a Raspberry Pi Zero, in my case
<?php
$command = "cat /sys/class/thermal/thermal_zone0/temp";
$temp = exec($command);
$tempC1 = ((float) $temp)/1000;
$tempF1 = ($tempC1*(9.0 / 5.0)) + 32.0;
$str = '{"cpu_temperature_F":'.number_format($tempF1,2).',"cpu_temperature_C":'.number_format($tempC1,2).'}';
echo $str;
?>
