Spoiler Alert Literally the day after I got the Echo to work with my home automation, there were a flurry ofannouncements about the Alexa Skills Kit. Thats a subject for another post. It turns out that this hack to do direct home automation is a better experience than what you can get by making an Echo app. Anyone who has taken steps toward home automation can probably relate to the feeling of wrongness that the Amazon Echo has such limited options for integrating into a smart home. I dont use the Belkin We. Mo system or Philips Hue light bulbs. But it just seems like I should be able to say, Alexa, turn on the kitchen light and make it work with my setup. Theres just enough already built in that not being able to do this is frustrating. Heres what I did to get it to work. My solution is general enough that it can be easily tweaked to work with many different technologies as long as youve got some kind of API available. My Setup. Does anyone besides me feel like the ability to tie multiple home automation technologies together, with reasonably scriptable APIs, has finally arrived It used to take tons of custom code to interface to each different component. More often than not, the technology got upgraded X 1. Insteon, for example before the integration code was finished. So I, at least, never got to the point of being able to use all those drivers from automation logic.

Ive built small Python modules that implement functions for common actions on each device. So I have an elk. I then provide a more or less unified RESTful API on an internal URL. Amazon Echos Current Home Automation Support. Until the recent addition of support for the Wink hub, the Echo knew how to talk to only the Belkin We. Mo switches and the Philips Hue lights. Thats great if you have those devices, but even with the added support for Wink, theres no overlap between my home setup and what the Echo supports. And the minute you want to do something more complex, say a macro that turns down the lights and turns on the TV, youre out of luck. The We. Mo devices use the UPn. P protocol to advertise themselves on the network, respond to searches from controllers, and define the details of their control interfaces. The Echo searches for the We. Mo devices specifically and is programmed to know about the We. Mo API. The minimal amount that the Echo uses the UPn. P protocol means that it should be possible to emulate We. Mo devices on the network in software. Finding out how the Echo and the We. Mo interact took some network sniffing with Wireshark. Because the Echo and We. Mo are both Wi. Fi devices, capturing the network traffic required a wireless adapter that could be put into monitor mode. This is often not possible under Windows. I used a USB Wi. Fi adapter on a Linux system and had no problems. The next obstacle is the encryption between the access point and the Wi. Fi devices. I wasnt willing to turn off my security. Wireshark can decrypt the traffic if you tell it your SSID and passphrase, as long as the captured data includes the four EAPOL handshake packets from each device. This handshake is done when the device connects to the access point, so Wireshark needs to be capturing when you plug in the Echo and the We. Mo. Heres an overview of the sequence of events that takes place when the Echo discovers We. Mo switches and then responds to a voice command to turn the switch on Emulating the We. Mo Switch. Creating a software emulation of the We. Mo switch would allow me to have as many virtual We. Mo devices as I wanted on my network, each with a different name. Each switch can be told to turn on or off, so the interface is pretty basic. But with an unlimited number of virtual switches, it doesnt cost anything to have one called Television, another called T. V. that does the same thing as Television, and one more called T. V. Mode that turns the television on or off and sets the lights to their desired states. Heres what I decided I needed for my virtual We. Mo cloud An IP address for each virtual switch. A listener for UDP broadcasts to address 2. A listener on port 4. IP address. Logic to customize the search response and the setup. UPn. P protocol and give the Echo the right information about each switch. Logic to respond to the on and off commands sent by the Echo and tie them to whatever action I wanted to really perform. I dont know that the Echo requires a different IP address for each switch or if I can use multiple ports on a single IP address or even multiple URLs on a single port. In theory, if the Echo honors the data sent in response to its searches and requests, it should be possible to just assign each virtual switch its own URL. But its also possible that the Echo is hard coded to use port 4. Pokemon Fire Red Omega Ips Patch on this page. POST to upnpcontrolbasicevent. I havent yet experimented to find the minimum conditions that will work, so I started by emulating each switch with its own IP address. With the Linux server Im using, its easy to create eth. IP address. 2. 39. UPn. P protocol. Only one such listener is needed since it can send multiple responses, one for each switch, in response to a search request. A search request from the Echo is a UDP broadcast formatted as an HTTP request, with HTTP headers indicating what is being searched for. There is no body. The search request comes from the Echos IP address and at least in my case port 5. The request looks like this M SEARCH HTTP1. HOST 2. 39. 2. 55. MAN ssdp discover. ST urn Belkin device Each UPn. P device on the network that satisfies the search term is supposed to send a UDP message to the IP address and port that made the search request. The response is formatted as an HTTP response. But this is not TCP, there arent really any connections involved. Buddha Serial On Zee Tv. One request from the Echo generates many responses depending on the number of switches on the network. The response from a switch looks like this HTTP1. OK. CACHE CONTROL max age8. DATE Mon, 2. 2 Jun 2. GMT. LOCATION http 1.

K0. 10. 17. 69 urn Belkin device In order to avoid potential problems with my switch emulation, I tried to make it as compliant as possible with the UPn. P specification and the actual behavior of the We. Mo devices. I suspect that the Echo is probably not very picky, though, and many of the details could be ignored. The 0. 1 NLS header is supposed to contain a UUID that changes with every reboot. I assign a UUID each time the virtual switch is created, which happens each time I restart my We. Mo emulation program. The X User Agent is not part of the UPn. P spec. However, this is what the We. Mo sends and theres at least one project on the web Ive seen where they look for this string to find We. Mo devices. The uuid part of the USN header is supposed to be persistent for each device even across reboots. Belkin appears to use the fixed string Socket 10 followed by the switch serial number.
