  • Uber Home Automation w/ Arduino & Pi

    This is all fantastic stuff and right up my alley. I am not only an IT Analyst by trade, but also have been a developer by hobby (as well as some freelancing) for more than a decade..finally I LOVE DIY, so openHAB, Arduino, and RPi are basically a match made in heaven. I just started on an automation learning project, so to speak, and have an android app I built that uses PubNub DSN and python on my RPi to control some 433 outlets in my house. Didn't take me long to get this far, and of course ideas are coming faster than I can get them done. Problem I soon realized, though, was that I wanted to automate things that are not just RF, like WiFi bulbs, light switches etc. So many commercial automation is very closed source and proprietary. Fine for most people, I guess, but not me. So I st...see more »This is all fantastic stuff and right up my alley.

Fine for most people, I guess, but not me. So I stumbled upon openHAB and it is great. I look forward to getting started on some of these projects. One question for anyone though - I assume I can build my own custom app, or modify the existing one, to better suit my needs and style? (I would share, of course :) ) Thanks!Mike

  • Super simple Raspberry Pi 433MHz home automation

    Thanks, I believe I finally got the code for the waves. One other question that, if I may suggest, could be mentioned in your tutorial is how precise do the intervals need to be? I ask because my calculations are actually an additional decimal place than yours are. (e.g. 0.000525). Also, I am not sure how far to zoom in to get this info. I am taking a couple of different samples of the long length and am getting some different numbers. (e.g. some are 0.000525 and another is 0.000609) Finally, is it fairly standard for the shorts to generally be half the longs? Mine are not - my shorts are measuring consistently at 0.00023. Thanks again! (Think I am almost there and hopefully my questions and your answers will help others as well)

    EDIT: OK, so right after my previous comment, I figured out I was using the plot tools wrong. I was zooming by rectangle and not the pan/zoom feature. That helps a lot. Still having a slight issue determining how to find a single pattern though. Will keep working on it, but if anyone has any suggestions, that would be great.

    Your tutorial is great; however, I am getting a little tripped up on the plot and what I am looking for. This is all fairly new to me, but generally consider myself fairly sharp when it comes to picking up new info like this. My plot doesn't look anything like yours. Do you know of any other sources of information on zooming and transcribing the waves? I believe I am using different plugs that you are here (I am using ZAP brand). It is picking up signal, but it seems I have to zoom in way more than you are here (also, my Y axis gets really small as I do it as well - I can't get it to stay at 1.0 like yours so the tops get cut off). Is there any easy way to pickup on a single instance of the signal? Testing the plugs with the handset, they work very quickly, so I am essentially just usin...see more »Your tutorial is great; however, I am getting a little tripped up on the plot and what I am looking for.

Is there any easy way to pickup on a single instance of the signal? Testing the plugs with the handset, they work very quickly, so I am essentially just using a single click, otherwise I will get a HUGE solid block on some of the buttons. Any help would be appreciated, I really want to get this so that I can understand it better. Thanks!

    So here is what I have determined is one cycle of signal coming from the first button. I think if someone helped me with this one, I would understand it better for the rest. Another question also, what the heck is at the end of it? The darker (and clearly MUCH faster signals at the end. Should I just consider this noise?
