  • Grafana
    Update 12-10-2016 Grafana is a tool that’s under heavy development and since this post was written it’s been updated several times and my use of it has evolved somewhat. Here are some links to up-to-date Grafana resources I’ve created: Github Gist, wherein I attempt to document in BASH-script fashion every...

  • SmartThings Multipurpose Sensor
    SmartThings was nice enough to send me a pair of their Multipurpose Sensors, which I’ve been meaning to pick up. These little guys pack 4 different sensors into a small form factor (which while small is not discreet), but you can only really use 3 of them at a time1....

  • Speed At Last
    ** Updated Oct 2, 2016 ** In a previous post, I described the state of my home Internet service. Today Spectrum (née Time Warner Cable) came by and installed my new high-speed service. This should tide me over until Google Fiber finally comes through. The Installation The installation went well;...

  • A Tale of Two Internets
    I’ve had two Internet setups at the house so far, with a third and – I hope – a fourth coming soon. Long-Term Evolution, Short-Term Solution As the neighborhood was new construction, options for Internet were limited at first, as only AT&T had installed any infrastructure. Because of city Planning...

  • Using GE Z-Wave Smart Dimmer Switches
    In a previous post I detailed the installation of a few GE Z-Wave Smart Dimmer Switches in 3- and 4-way installations. In this post I’ll detail more of the implementation. Inclusion Inclusion is the process of “including” a Z-Wave device into a network. Usually it involves two steps: put your...

  • Installing GE Z-Wave Smart Dimmer Switches
    Disclaimer: This post is not meant as advice or tutorial for performing electrical work. Treat it only as food for thought when considering your own electrical projects. Every house is different: there is no guarantee what color your wires will be or how exactly your switches are wired. I haven’t...

  • Raspberry Pi Serial Server Part 2
    In Part 1 I detailed attaching a Raspberry Pi to my Monoprice 6-zone amp via a serial cable and getting them talking with the help of a Node-based app. I left off after suggesting that my end goal was to integrate the Amp into my SmartThings ecosystem using this Rpi<->Serial<->Amp...

  • Raspberry Pi Serial Server
    I have an old Raspberry Pi sitting around. It’s one of the first or second edition Pis, the kind that uses a full-size SD card and doesn’t even have any built-in Wi-Fi. I believe it is a Raspberry Pi 1 Model B. It’s still a capable little computer even if...

  • Z-Wave Project Board
    When it comes to smart home or home automation doo-dads, some you put a battery in and stick on a shelf; some you plug into the wall wherever you want the thing. But yet others require you to open up a part of your house and dig around in its...

  • Assembling a 12v Water Valve
    I just picked up a few knick-knacks with which to start prototyping part of an implementation for my irrigation-related use case. In this article I’ll be assembling a 12-volt water valve that I will use in tandem with a Z-Wave dry-contact relay to automate filling my 500+ gallon rain tank...

  • SmartThings SmartSense Temp/Humidity Sensor
    When I first got my SmartThings hub (version 2), I didn’t have much in the way of Things to connect to it. I did have some rough ideas of use cases in mind, so instead of a bunch of switches I went for the low-hanging fruit: battery-powered sensors. Along with...

  • Automating the ERV Part 3
    In Part 1 I leveraged the Z-Wave functionality I’d added to my ERV to create some basic automation for its operation. I implemented a SmartThings routine to begin high-speed ventilation on demand and, not liking the open-endedness of that, wrote a Smart App to shut the thing down again after...

  • Automating the ERV Part 1
    Previously, I wrote about adding Z-Wave functionality to my ERV. With that in place, I can use SmartThings to perform automation of this appliance in an intelligent manner, or at least with something approaching intelligence. A good place to start is to automate some of the operational features that would...

  • Adding Z-Wave Functionality To My ERV
    I previously described the low-voltage wiring block on my ERV and how I intended to use it to hook up some smartness: In a purely mechanical world, I could use a 3-position switch to make these connections, where the ON terminal is the common line and I switch it between...

  • Aeon Labs Smart Switch 6
    When it comes to switching things on and off via Z-Wave, you don’t have a lot of options. You can buy an appliance that has Z-Wave functionality built in, you can install a Z-Wave module behind your in-wall switches or replace the switch entirely, or you can use a plug-in...

  • The Dashboard (Part II) - Logstash
    I was wondering if I’d have a use for Logstash in my ELK Stack. So far I’ve used Elasticsearch (the “E”) and Kibana (the “K”) in setting up a dashboard for my home. It turns out there is a reason to use Logstash (the “L”) after all. Bulk Data While...

  • SmartThings
    I added a page for Samsung SmartThings to The Tools collection.

  • Kibana Memory
    Kibana and Memory Last post I left off having just set up Kibana. In the meantime I’ve added some more data to my Elasticsearch database and created some visualizations and dashboard in Kibana. Then my Raspberry Pi ground to a halt when Node decided to use all the memory and...

  • The Dashboard (Part I)
    An important component to a smart home is tracking the sorts of things that the house is trying to tell you and putting those facts in context with things you already know. One of the tools I’m using is an ELK Stack, which will let me develop a dashboard on...

  • First Steps
    This is my Intranet of Things blog. It’s new, it’s built in Jekyll and hosted in Github Pages. I’m not trying to win any design awards, but I do want to evolve a bit from this stark utilitarian default theme. I chose Jekyll because “Why not” (which is more or...
