Yeap, thats the one. It’s a lot smaller than you’d expect, it’ll only have shortish radio xmit since the antenna isn’t external. In the US there are a few place flogging these off for $15-20ea, and they’re low wattage during xmit operations.
[quote=“Brientim, post:80, topic:167178”]Have a look at the TP-Link TL-WR702N.

Yes, that would be small enough to make it a go. I just had a thought… what about a USB dongle sized 802.11 B or G adapter (client)? Those are even smaller, cheaper (nearly free) … if they would transmit something to your existing Wifi AP that could be seen by the Vera we’d be good.
doable?
@Aaron, the USB dongle on it own won’t work as it would be dependent on a PC or something to get it up an running with drivers etc.
Doesn’t get much cheaper than that! I thought I recognized them, they are the same routers that are linked from this post by the eBay vendor:

More expensive there as I guess they are loaded with some custom firmware.
For the ultimate in small (not really cheap) then an eye-fi card might work.
So assuming the TPlink AP… is there code that would use it?
The code running on the vera will need to somehow detect/poll the access point (since most will be using an access point that is not the vera itself) and look for a specific MAC address or IP address.
thoughts on how to make this work?
Just need to load the Ping sensor from the app store, associate the wifi access point in bridge mode, give it a static address (or static DHCP assignment), then enter this address in the ping sensors configuration.
I don’t want to look paranoid, but this TPLink with not-so-clear sources makes me thinking… You know, plugging unknown boxes with customized firmware into your network can lead to some interesting experiences. They can open SSH tunnels too, just like Vera does, but to other places - giving outsiders nearly unlimited control over your network. People actually do that.
I’ll probably get one - but I’ll make sure to block it from opening any conection to the outside world (same should be done to all “uncontrolled” inexpensive IP cameras originating from the same place)
but do you really want to keep this device hooked up to the car’s battery 24/7? :-\
I doubt it would cause much drain!
in most modern cars the 12v power plug is turned off when you turn off the car.
Then how do you discern between events of coming back from work vs turning on the engine in the garage?
Easily. 
I explain in one of my previous posts
Well… if wifi power is off you have no way to know if it’s just off or the car is away
This would be interesting and always on alternative

As I explained in my post, the code tracks status. It is dead simple for anyone who knows even basic coding.
TP-Link TL-WR702N mini portable AP/bridge
$20 shipped!
… I may just get one!
only downside is according to many posts (Amazon, Focalprice, etc) the UI is in Chinese and cannot be changed to English. BUT, I did confirm the docs posted online at TP-Links web site are fully in English. Very odd.
update … just found the UK firmware posted… Download Center | TP-Link United Kingdom
Good deal, I’d almost be tempted to buy one myself for a spare travel router, or to have a stab at something like this myself.
Make sure you post how you get on with this project!
I would get the TL-WR703N model instead, it appears to be the exact size but has more memory and possible to run OpenWrt on: TP-Link TL-WR703N [Old OpenWrt Wiki]
Great idea. I have an unused eye-fi card since I’ve replaced to a mini-sd based camera.
I will try to plug in the eye-fi card into the SD slot in my car’s audio system and see how it works.
Please let us know if the eye-fi Card works. I have one also.
[quote=“dj2020, post:69, topic:167178”]I want to say thanks to Woodsby for the plugin and the others who contributed to this thread. I just installed the garage plugin with the Evolve LFM-20 relay and Everspring SM103 sensor. It works like a charm!!
Curious for those who use the Everspring sensor, what kind of battery life are you guys getting . . . especially with the more extreme temperatures of a garage?[/quote]
hi dj2020, i am also planning to use LFM-20 and SM103-1. may i ask if you are now able to control your garage door through your smart phone? are you able to see the status in your smart phone. thanks in advance.
