dscKeybusInterface reviews and mentions

• Ask HN: What have you built with ESPHome, ESP8266 or similar hardware
  26 projects | news.ycombinator.com | 27 Apr 2024

  Brought an inactive home security system onto Home Assistant using the below repository, so I can track everything from smoke alarms to motion, doors, and windows. I swear there's a niche business opportunity in retrofitting all these deactivated systems!

• I'm a security technician. I found out where all our Pis are going. Access control panel I'm working on:
  1 project | /r/raspberry_pi | 20 Jun 2023

  The sensors themselves are relatively easy to defeat, a strong enough magnet in the right position and you can pop a door or window open without tripping the sensor. This specific DSC panel was chosen as the bus protocol was unencrypted(the only reasonable attack would be a playback attack, everything needs a user, master, or installer code), but it would be relatively easy to add an esp8266 behind the wall plate of a keypad. (take notes, this is why you should have motion detectors wired inside, and add latching tamper zones). I don't have to worry about the encryption issue, since the keybus line doesn't go outside of a locked closet, which will probably use the latching tamper preset.

• Connector identification
  1 project | /r/arduino | 18 Jun 2023

  Additional context for anyone that's trying to google the same thing. DSC power series pc1816, pc1832, and pc1864 main boards use this connector for the battery harness, which is difficult to source. (This sub is also relevant as there is a DSC key bus Protocol library for Arduino or espressif boards, this was one of the last boards they made before the bus line was encrypted).

• Upgrade from DSC Powerseries PC1555
  1 project | /r/homesecurity | 27 Dec 2022

  Actually it's not "dated" as much as it's "timeless" :) Things get a lot easier with a serial cable and the DLS software. You can even build your own Envisalink like module that works with Home Assistant, for about $6, see: https://github.com/taligentx/dscKeybusInterface

• DSC Powerseries NEO keybus interface?
  1 project | /r/homedefense | 18 Aug 2022

  There is a lot of work done for DSC powerseries keybus interface (not the NEO version): - https://github.com/taligentx/dscKeybusInterface - https://github.com/taligentx/dscKeybusInterface/tree/expander But I cannot find any documentation online for the NEO version.

• Best communicator for PowerSeries with IT-100?
  1 project | /r/homesecurity | 11 May 2022

  What's the main goal here? The EnvisaLink™ EVL-4EZR module works really well with home automation like Home Assistant or, if you want a less expensive solution taligentx / dscKeybusInterface is an open source solution which can run on a Wemos D1 mini (< $10). Both of these solutions appear to the DSC panel to be a keypad so unless you exceed the maximum number of keypads for a given panel then you should be OK.

• Service options with DSC PC1616
  2 projects | /r/homesecurity | 3 Mar 2022

  Speaking of DIY, you can build your own for under $10 in components and use opensource software like taligentx / dscKeybusInterface, then monitor yourself with Home Assistant. There is even open source software to recover the installer code. So the options for such an panel are not limited.

• If your alarm system is no longer being monitored by a company and you set the alarm off, would it still dial to the old company?
  1 project | /r/homesecurity | 17 Jul 2021

  I'm wondering because I'm planning to run this project on the system to recover the installer code. I'm a little worried that doing so will start dialing to the old alarm company.

• Don't have installer code for old DSC PC1555 (defaults don't work). Would it be straightforward to replace with a DSC PC1616 or DSC PC1832?
  1 project | /r/homesecurity | 26 Jun 2021

  Did you check if https://github.com/taligentx/dscKeybusInterface would support to unlock it? It would only require an arduino and a few days maximum to run (most likely a few hours). I've done it on my panel although it was more recent.

• Ademco Central Office reciever manual
  1 project | /r/homesecurity | 11 May 2021

  If one doesn't like the $100 cost of Envisalink, with DSC systems there is open source software on GitHub that uses a $5 Wemos D1 mini board and another $1 worth of electronic components (couple resistors and a transistor) to interface directly to the KeyBus and then provides several methods of control.
