There seems to be some python code out there for the IT-100, which I’m hoping someone can work into Home Assistant.
A Python driver for the DSC IT-100 integration module
Just a follow up my earlier post to see if anyone has made any progress with getting Home Assistant to work with a DSC Alarm panel via their IT-100 (RS232) module.
It would be a great addition.
Having same problem getting home assistant to work with IT-100 module. If someone have figured it out it would be great.
I’m not sure if this helps - but while I’m not using it with HASS, I am using my IT-100 with my Vera home automation controller via a raspberry pi , USB to serial cable (running ser2net)
That allows me to connect to the it-100 which is connected to my DSC panel over Ethernet/IP like Envisalink
I am interested in implementing this. Python is not my native language but I should have no problem putting something together. That driver linked above seems pretty simple to use. I can’t commit to making this fully featured but I’m pretty sure I can get some basic functionality up for this. Has anyone already began any work here?
Hi @pho3nixf1re
I’m not aware of anyone starting on this so it would be great to have the IT-100 supported. If I can help with testing please let me know.
EDIT: Ignore the code in this post, use the github repo at https://github.com/SolidElectronics/evl-emu
I’d like to see a native driver as well, but in the meantime I wrote this.
It’s a service that connects to the serial port and emulates an Envisalink so Home Assistant can use it. I haven’t tested this extensively, and I offer no guarantees it will work, but I thought I’d share it in case it’s useful to someone. It’s written using the Python multiprocessing libraries so it spawns several processes that each perform one task. Ideally this would be rewritten in a cleaner way with asyncio but that’s currently beyond my ability.
I have this running under Hassbian on a rPi3 with the DSC panel connected via a serial-USB adapter at /dev/ttyUSB0. Note: It requires the ‘pyserial’ module for interacting with the serial port.
Include this in /etc/rc.local to automatically start after boot.
/bin/su -c '/home/homeassistant/.homeassistant/evl-emu.py >/dev/null 2>&1' homeassistant
configuration.yaml
envisalink: !include envisalink.yaml
envisalink.yaml
Change 0000 to a valid code (for arming and disarming the panel)
I only included two zones here, and it probably only works with one partition.
host: 127.0.0.1
panel_type: DSC
user_name: user
password: pass
code: '0000'
zones:
1:
name: 'Front door'
type: 'door'
2:
name: 'Garage back door'
type: 'door'
#...
partitions:
1:
name: 'Alarm'
/home/homeassistant/.homeassistant/evl-emu.py
Change the SERIAL_PORT to match your setup. If possible, create a udev rule to make the USB-serial adapter always show up as /dev/it100.

Thank you so much @SolidElectronics! This was such a tremendous help! I am finally up and running using the DSC IT100 USB adapter connected to a Pi2 running hassbian. The emulator works great!
I had two snags in my setup:
-
I was getting a connect error in the logs. I checked and discovered that evl-emu.py was not running (listening). This was even after I included your line in /etc/rc.local. I worked around it and piped the output to a log file.
-
Once the emulator was listening, I got the following error: “device reports readiness to read but returned no data.” I figured another process was already using the serial-USB adapter, so I commented out alarmdecoder in configuration.yaml
envisalink: !include envisalink.yaml #alarmdecoder: !include alarmdecoder.yaml
Restarted both the emulator (evl-emu.py) and HA, now it’s working like a charm! Thank you, again, for sharing!
@SolidElectronics - great work on this - I thought I would reach out to see if you have updated the python script at all or if you had it on a public repo?
Thanks for the suggestion, I’d been meaning to put it in a public repo but never got around to it until now.

Since the original post I switched over to running HA inside Docker and moved this script to a standalone Pi1 but there were essentially no changes to the script other than updating a couple of IP addresses and the device name.
@SolidElectronics - awesome; thanks! I am running it the same way as well (an external PI (away from HA)).
All, I wrote up the process on how I got HA working with the IT-100 using @SolidElectronics script - works great and response time is nominal for the binary sensors as well.

Hi @cbschuld, I followed the instructions you posted on your site using a fresh RPi 3 B+ and a known working USB to serial converter (known working, as in it was doing the same job with openHAB, which I am moving away from).
Unfortunately, I just cannot get this working! I tried a commit from Feb (9b3eb4c), considering that was closer to when you posted your instructions (after I couldn’t get the latest working), and there is definitely more output in that version.
I can see what I assume to be serial input and output (the EVL In and EVL Out) when running the script manually, and it also shows the IP address of my hass.io instance making the connection.
The defined sensors matched up with my zones are not reporting status in Home Assistant, nor are the arm actions working - when I send an arm request, I can see that the script sees it (I get an EVL In, with a bunch of data), but nothing happens.
Was hoping you or @SolidElectronics might have some pointers?
And since I posted this, I dug a little deeper… Still not working properly, but at least I know what’s going on…
My baud rate isn’t set to the default 9600, and is instead 115200. I changed that, and then was getting responses from the panel (I assumed I was getting responses from the panel before, but looks like it was just responses from the IT100 module only).
Only problem is that it is detecting all data from the panel as having a bad checksum. To confirm if the data was really bad, I commented out the lines in the script that validate the checksum, and was finally able to see the state change in Home Assistant for the zones!
However… as soon as the scheduled blob of data comes through (I guess regular polling or something?), it wipes out the current reported status. This is the chunk of data I am talking about: -
[14:09:05] EVL Out < 36:31:35:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:39:43:0D:0A 61500000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000009C
Once that is received, all zone statuses are wiped out and they go back to being “closed” or equivalent.
Would the checksum change with the baud rate? I wouldn’t think it would make a difference, but I don’t have a great deal of experience.
Hi @ebadayon
First things first, I’d really try to get the latest version of the code working, there definitely some bugs in the older version, mostly around HA not being able to reconnect after it restarts.
The EVL Out messages are the ones being sent from the script (pretending to be a real EVL) to HA, likely in response to HA occasionally polling the status. The ‘615’ message is the EVL sending the zone timer values back to HA. A value of zero means they’re basically uninitialized (EVL has never seen the zone close). When a zone closes, the value gets set to 0xFFFA and counts down by one every 30s.
The checksum is defined in the DSC IT-100 interfacing guide, it’s definitely not supposed to be dependent on baud rate.
Can you try the latest code version and send me a full debug output and I’ll see if I can make any sense of it?
@SolidElectronics, thanks for the reply! I’ll give the latest code a go when I get back home tonight (I’m in Australia). I did try the latest version first, but that was obviously before I sorted out a couple of my other local issues.
Is there a particular or preferred way to obtain the debug output?
@SolidElectronics, when I run the latest version (after updating the baud rate and device), I get the following output only: -
Process Process-2:
Traceback (most recent call last):
File "/usr/lib/python3.7/multiprocessing/process.py", line 297, in _bootstrap
self.run()
File "/usr/lib/python3.7/multiprocessing/process.py", line 99, in run
self._target(*self._args, **self._kwargs)
File "./evl-emu.py", line 264, in serialRead
logger.debug ("{} DSC In > Checksum error".format(timestamp))
NameError: name 'timestamp' is not defined
Edit: When I get rid of the .format(timestamp) off the end of the logger.debug, I get no output at all after executing the script (left for 5 minutes with nothing at all happening). There’s also no status update in Home Assistant when I deliberately trip sensors, so it doesn’t appear to actually be doing anything now.
Interestingly, I seem to be able to issue commands to the DSC panel now (I was able to arm the system), but I am not getting anything FROM it (it didn’t know it was armed, it doesn’t report zone changes, etc.)
EDIT: I have a workaround, which is basically to…
- Set “
zonedump_interval: 0” in my yaml to prevent zone status from being overwritten every 30 seconds - Use the initial and original commit from Feb 21 which is the only version of the script that seems to work for me!
- Comment out the checksum verification code to allow the data to actually be received
The last item is obviously less than ideal, but I have no idea why the checksums are failing for everything when the data is obviously valid. Would be great to be able to work out what’s going on at least with that last point!
I was able to fix the timestamp issue, thanks for finding that. I’ve never had a checksum error that causes that section of code to run. 
I’d still like to see the a log of the interaction between your panel and the software to see how it compares to the specification document from DSC. Can you tell me which panel and serial interface you’re using? I’ve got a Power864 with an IT-100 at 9600 baud, which is really the only thing this has ever been tested with.
I attached a log of what mine does when starting up if you want to compare it.
It starts the serial read/write processes immediately, then waits for HA to connect. When that happens, it starts up the network read/write processes and message handlers. After doing the initial connection and login stuff, HA will send a status request message (001 91) that causes the panel to start dumping out its software version followed by all the partition and zone status messages.
