I'll still continue building it even if there are already tons out there. There could be features that are not implemented on that existing product mentioned above but I'm not sure which product you are referring to when you said "it's already being done".   Also,  there'll be 20+billion devices...

:) It's ok. It's not only for ELK. Thank you.

You mean which Elk? Actually any device as long as there is a serial port and rs232 manual where I can learn about the product's api.

Because it's fun to write. I'm going to learn writing it. The web application will be a responsive website which means it will work in desktop, laptops, and phones. Also, the program I'm developing will not only be dedicated for ELK but can be used anywhere though I will have to write an...

Just an update. I took a video of my phone beside my laptop and asked my son to walk so that the sensor in the living room and family room will be triggered :)   https://www.youtube.com/watch?v=oqy2UibmEgo

I'm so happy tonight because I accomplished the goal I started last week. I am now able to control my sprinkler system as well as realtime monitoring of the motion sensors from anywhere such as laptop or phone. I can now focus on the design and I'll make sure the UX will be really nice. Right...

Thanks.

Hi folks,   I can't find information about the voltage on the built-in serial port on ELK-M1 gold. Can someone please help?   Thanks!

Yup, that should work. I actually just bought a beaglebone. I had a $30 amazon gift card from last Christmas that I just remembered this evening. I'll use it as the gateway instead of my old dirty computer :D I'm very excited!

The reason why I'm doing this is because I can't afford to buy the Ethernet module. So I'm going to take advantage of my old computer which will run linux. I'll build a NodeJS application programming interface so it can accept HTTP request. I will parse the request, massage the string, calculate...

I forgot the names of the modules. However, I just use the serial port on the M1 and I hook it directly to my computer. I'm not sure what XSP is

  Just a regular usb to db-9 cable(my mac doesn't have 9-pin serial port). I had to install a usb-to-serial driver on my mac so that osx will create the device in /dev. The block device that gets created when I connect to my M1 is /dev/tty.usbserial

  You're very welcome! :)

Here is a new version. It pads zero if result is a single character   pad = function (str, max) { str = str.toString(); return str.length < max ? pad("0" + str, max) : str; } function generateChecksum(command) { var sum = 0; for (i = 0; i < command.length; i++) { sum +=...

if in case someone in the future also needs it, they'll find it here. It might help me too if in case I lost my code in the future   function generateChecksum(command) { var sum = 0; for (i = 0; i < command.length; i++) { sum += command[i].charCodeAt(); }; sum = -(sum % 256) &...
