We moved to Georgetown Texas in September.  I left my Elk M1 Gold behind.  The Georgetown house, built in 2005, is equipped with a DSC1616 alarm system with one keypad; all the doors and windows appear to be equipped with wired sensors.  Previous owner never used the system.   I'm open to...

http://plantpi.gabrielbarnes.co.uk/   Arduino and Raspberry Pi source code to make 24L01's talk.   PM me for other links on 24L01

Just an FYI, you might consider the Arduino Nano v3 (clone) (~$11) and a mini breadboard (~$5) as a way to get started. You'll need some male-female jumper wires to get started.  That's a cheaper route than an UNO R3 or even a Raspberry Pi. Warning: this hobby can get addictive; fortunately the...

  Similar yes.  I have an Insteon ISY994i Pro with the Elk Integration module.  I have ~20 Insteon devices (lamp modules, switch modules, sensor / relays and motion sensors).  The ISY994i handles all the scheduled lighting events and reacts to Elk zone violations.  See some of my other posts for...

  I have nRF2401's working on Arduino Unos, Raspberry Pi's and an Arduino Nano on a small breadboard.  

I've had success getting Raspberry Pi's and Arduinos communicating wirelessly using Nordic Semiconductor nRF24L01.  The modules operate in th 2.4ghz band.  They are les than $5USD and well documented in both the Arduino and Raspberry Pi libraries.  ...

  PSC05 isn't required, since PLM module attached to ISY994i handles all communication with Insteon as well as X10 devices.  PLM sends signals over the powerline as well as wirelessly, so dual-band Insteon devices will react to either signal.  Head over to Universal Devices for an intro

  Actually, my initial design thoughts were more along the lines of a network of Arduino-compatible processors with sensors and low-cost wireless communication, 9v battery power communicating with a Raspberry Pi running Apache2 web server which in turn communicates with the Network Module on my...

To each his own I say.  I have the same setup but my ISY perform handles all the scheduled lighting events as well as reacting to sensors and Elk zone violations. e.g. lamp comes on when an exterior door has been open for more than 30 seconds.  Prior to getting the ISY and replacing all my x10...

I've been playing with several, using a Raspberry Pi and Arduino UNO.  The DHT-11 and DHT-22 sensors do both temperature and humidity.  The TC74A does temperature, but requires the i2C communication protocol, readily available on both the Pi and the Arduino.  The DS18B20 (Maxim) is a 1-Wire...

+1 on assigning static IP addresses to both the ISY994i AND the M1XEP.  Experience is the best teacher and as attractive as having the router assign IP addresses via DHCP can be, you will have less headache using static IPs on these two devices.  Just be certain you select two IP addresses...

  Great to hear it worked for you Rich.  "Free" is nice when it works!

FWIW, you might consider acquiring an ISY994 from Universal Devices.  By adding the Network module and the Elk Integration module, you could "listen" for any Elk event (e.g. zone violated) and have the ISY994 react.  You can host web servers on the ISY994 and they in turn could notify your cloud...

Have you tried using the non-secure port 2101 instead of the secure port 2601?  My Windows 8 desktop refuses to connect on 2601 but does so willingly on 2101.  What version of Elk RP2 are you using?  If version 2.0.18 is caused difficulties, switch to the previous version 2.0.16.   Assigning the...

  Elk M1 Gold with M1XEP and ISY994i PRO with Elk Integration module is serving me very well.  Others will disagree, but I subscribe to the "best of breed" philosophy, let the Elk monitor zones and alert and let the ISY994i sense everything going on.  ISY994i and folks at Universal Devices are...
