UPnP implementation for Arduino, and on ESP 8266
This is a library containing a couple of simple classes to implement a UPnP device on an ESP8266.
The demo is a MotionSensorService class which can be detected with SSDP :

...
Device #5 {UPnP Motion Sensor Kit}, url http://192.168.1.100:80/description.xml
Service {urn:danny-backx-info:serviceId:sensor1}, url /scpd.xml
type urn:danny-backx-info:service:sensor:1
and that produces (debug) output such as this when queried

Sample queries are provided in examples/UPnP/scripts . Note that the getVersion script invokes a function that should return XML, but I'm a bit lazy : the output isn't valid XML.
This is the output of the example that does produce sensible XML :
Query 192.168.1.100 ...
<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<s:body>
<u:GetStateResponse xmlns="urn:danny-backx-info:service:sensor:1">
<State></State>
</u:GetStateResponse>
</s:body>
</s:Envelope>
The only hardware you need for this is an ESP8266 device and a motion sensor.
You can build this application via the Makefiles supplied, or from the regular Arduino IDE. Either way, you'll need to supply a file called
mywifi.hin each application directory, with contents such as
#define MY_SSID "my-wifi-ssid"
#define MY_WIFI_PASSWORD "secret"
