Most alarm systems are hilariously simple.

It’s entirely possible the domain exists but only resolves and accessible within the corporate network. To quit, that is, specifically stating that.

Follow all reddit rules and obey reddiquette.

As a developer, I would refuse to work under those conditions. As well, all the zone names basically everything about them can be read and changed over the RS interface so this plug-in just reads them all in – no setup required. I accidentally used ‘decompiled’ where it should have been ‘extracted’. It works on all boards above the Vista20 full-sized boards – even old ones but only the latest boards the BPT series have the RS level shifters built in so no additional hardware is needed.

You’ll have to excuse any issues in my blog post as it was my first time doing any of this. Did you miss your activation email? Does that mean all the sensors are some industry standard stuff that would work with something different? The sensors are just contact closures, sometimes with a resistor or two worked in. A lot of it could be considered illegal, but it is rarely prosecuted. First, I wouldn’t call myself an expert either so no problem!


Can you post a pic of the control panel?

Honeywell/Ademco Alarm Panel Plugin Development (RS)

Check out our Community updated “known to work” device list. There was actually a post a while ago of exactly that if I recall, where most people said exactly that. Yeah, that’s what you get for making the assumption that the extension has any canonical meaning. In the longer term, Honeywell has a nice home automation interface board called the CBM which appears to solve all the issues associated with using the ECP bus. Lua just keeps restarting over and over. Github is a major resource for those groups.

Welcome to Reddit, the front page of the internet. No Personally Identifying Information! I might be able to help. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. The ECP serial protocol used to talk to the keypads has been reverse engineered in a few places it’s just bps ttl serial.

Reverse Engineering My Home Security System: Decompiling Firmware Updates : netsec

I see there has been no activity in a while, so I would like to know current status of your plugin. Smart Home, made easy. These these boards work with the ECP adsmco options as well – just slower responsiveness and more complex setup.

I would suggest starting with sniffing the RF traffic of your system.

Keypads use 4 wires- two for DC power, two for a simple serial data bus. Simply adding sendRequest “08ZPE” before the call to loadPartitionData fixes the problem with the partitions not loading. The folks who have them rarely let them go until they have to. Decompiling Firmware Updates markclayton. Several of the big name HA guys use it adeco Control4 and others. Ask questions in our Discussion Threads. Alternatively if you don’t care about alarm functionality, rip out the alarm panel and put an arduino or RPi with lots of GPIO pins that will sense the state of each sensor and report them back to your HA system and blueiris.


I don’t think the sendRequest matters much, it just needs to be a valid request. Honestly I would rather not break it or physically poke and prod at it and cause an issue.

Just because you can’t hit it, doesn’t mean it’s not in existence. Some just don’t want you posting code, or commenting on any forums including GitHub. Honestly if it were the industry I was in, I’d avoid American companies like the plague because of the way the law is there. But security research has always existed devvelopment a legally grey area.

Just looking for that response and resubmitting the request one or two times until it’s seen would probably fix this issues. Keep the discussion on topic. Keep up the work! I find it annoying that Windows doesn’t look at file headers when there is no extension, and that not every linux application tries to use an extension for ease of use.

I’m also working on some updates to the RS plug-in because I ro to migrate to that soon because of it’s benefits. Content should focus on the “how.
