SumnerBoy:

I have a few of these (http://www.wemos.cc/Products/) - their shop link just takes you direct to Aliexpress. They are a very small size and have some cool little shields which makes life easy for prototyping. And also got a few of these (http://www.electrodragon.com/product/wifi-iot-relay-board-based-esp8266/) which are pretty impressive for the price - case included!

I have Homie running on both and they seem very reliable/solid so far (early days admittedly).

Thanks for the links, I was just about to ask the same question.

Slight improvement on the code, as I use Amazon Echo (Alexa) to open or shut the garage door - if I tell her to open it when its already open she shuts it and visa versa.

For brevity, this just makes sure if I say "Alexa, shut the garage door" and its already shut, she won't open it and if I say "Alexa, open the garage door" and its already open, she won't close it.

Change line in Arduino code where it says if ( msgString == "ACTIVATE" ) { to this:

if ( (msgString == "ACTIVATE" && doorState != DOOROPEN) || (msgString == "DEACTIVATE" && doorState != DOORCLOSED) ) {

Change Openhab sitemap file to this:

Frame label="Garage Door" {
Text item=doorStatus
Switch item=doorButton mappings=[ON="Open", OFF="Close"]
}

Change OpenHAB items file to this:

/* Doors */
Number doorStatus "Door Status [MAP(switch.map):%d]" <garagedoor> (gGarage) { mqtt="<[mqttbroker:openhab/garage/doorstatus:state:default]" }
Switch doorButton "Garage Door" <garage> (gGarage) { mqtt=">[mqttbroker:openhab/garage/doorswitch:command:ON:ACTIVATE],>[mqttbroker:openhab/garage/doorswitch:command:OFF:DEACTIVATE]" }
