My garage door is a tubular motor, with a remote control receiver in a 433MHZ. Remote control batteries run out one day, but not long after I replace the battery, find the remote control receiver is bad. After a few days to manually open the door, I decided to make a controller that can support mobile remote control.

Step 1: ​Research Motor

I look up some manual of tubular motor, found that it has four lines, grounding wire, an N lines and two control lines. By change the connection of L line and two control lines, you can achieve positive reversal.

Step 2: WIFI Relay Design

I chose MT7681 as WIFI module, and designed

a relay module with it. I chose the MQTT protocol for remote control via the Internet. Because MQTT has open source server programs, and also has free cloud services.

I want to put it in an aluminum shell, but manufacturers require a minimum number of processing is 100.

Step 3: The APP

Because I'm not very good at developing mobile phone APP, so I make a simple application using PHONEGAP with HTML5 and JAVASCIRPT.

Step 4: Wires Connection

Step 5: Finish

I configure the controller's broker address

to iot.eclipse.org, now I can use the mobile phone network to control the garage door.

<p>Hello, Could you please share, where to get MQTT code for MT7681?</p>
<p>Hello, would you mind sharing the MT7681 code for this project?</p>
