I am interested in building a Raspi garaged door monitor and remote open & close web application but all the tutorials on the internet or YouTube are incomplete. Would it be possible for know how to do with a pi or arduino

I use Arduinos for all my home automation sensors and controls. Low cost and easy to build. I use the MySensors.org plug in for the Vera Lite home automation controller to interact with my sensors. Very low cost and easy home automation solution. I use an app called Imperihome on my wall mounted tablets and phones as well as the web interface on Vera to control the sensors and relays. Since I can't add pictures here, this is a couple photos of my controllers.

http://lowpowerlab.com/garagemote/#whatisit    uses an arduinoclone with radio to control door.  Communication via Pi for remote access.  Good pics and tutorials on software for both.

Roy Z There is some very nice components at that link. I have not seen those before. A bit on the pricey side per sensor or switch. But if you only need or want to automate a couple items, not a bad way to go.

A friend of mine helped start a company called Garageio (https://garageio.com). I've lost track of how they're doing, but their early prototyping was done with a Raspberry Pi.

 

I've wanted to start this same project a few times, but still haven't gotten around to it. The concept is super simple. I especially like the idea of using the Pi somewhere in the mix, but as Scott said, there are somewhat simple to use products already made.

Scott W maybe we've discussed this before, but I'm a bit concerned about the security of the MySensors projects. I love that it's open source and has a great UI, but it seems like it would be relatively easy to hack. The only security I've seen added on was an encrypted signature accompanying the message. Since NRF24L01+ chips are so cheap and readily available, I the signed key idea should probably be the bare minimum.

 

Do you have any opinion on the topic or know if MySensors are otherwise protected from replay attacks?

Ben Reese Hey Ben, I think we have talked about this before. I personally have done minimal research on security with the MySensors project, and actually I am not very educated on how to secure them. I live way out in the sticks, closest neighbor is about a 1/4 mile.  My sensors are on on their own LAN not connected at all to the internet, for me I don't need them to be. The last time we brought it up I bookmarked a couple forum topics dealing with security and have not read them yet.

Maybe you can make sense of them and fill me in.

Scott W actually, that second one is a lot more in line with what I had thought of. I'll definitely have to bookmark that and check it out later. I don't know if is implemented in that or not, but I'd want a unique key for each sensor and a way to store those keys securely on the hub. Pretty good stuff regardless!
