Elk-M1 Control
The Elk-M1 is a home security and automation controller that is capable of alarm control panel functions and automation.
The Elk-M1 controller is manufactured by Elk Products
There is currently support for the following device types within Home Assistant:
-
Alarm - An ElkM1 area (also known as partition) is represented as an
alarm_control_panel
. -
Binary sensor - ElkM1 zones that have 4 states (i.e.: are not analog zones) are represented as
binary_sensor
entities.Normal
isoff
and any of the other values ison
. -
Climate - An ElkM1 thermostat is represented as a
climate
entity. -
Light - An ElkM1 light (which can be X10, Insteon, UPB) is represented as a
light
. -
Scene - ElkM1 tasks are represented as
scene
entities. -
Sensor - ElkM1 counters, keypads, panel, settings, and zones are represented as
sensor
entities. -
Switch - ElkM1 outputs are represented as
switch
entities.
The implementation follows the Elk Products ElkM1 “ASCII Protocol & Interface Specification, Revision 1.84” document. This document can be found on the Internet.
ElkM1 configuration and version
In order for the ElkM1 integration to work to its fullest with Home Assistant the ElkM1 panel must be configured correctly. This section describes the configuration required on the ElkM1 panel.
ElkM1 version
ElkM1 should be running:
- Version 4.6.8, or
- Version 5.2.0 or higher.
Force arm away and stay are available in 5.3.0 or higher.
Many features will work with lower versions of the ElkM1. Check the “ElkM1 RS232 Protocol” manual for details.
ELK-M1XEP version
The ELK-M1XEP is the Ethernet controller board for the ElkM1. If connecting the integration
in secure mode the version of the ELK-M1XEP determines which secure protocol is supported.
ELK-M1XEP versions less than 2.0.46 support TLS 1.0, while version 2.0.46 and above support
TLS 1.2. When adding the ElkM1 integration in the user interface use secure
for TLS 1.0 and
use TLS 1.2
for TLS 1.2. Note that ELK-M1XEP does not support auto-negotiation of the
version of the TLS protocol, the user must specify the TLS version to connect.
Global Setting 35
The ElkM1 integration tracks the user number and name of the last username to
arm or disarm the panel. The changed_by
and changed_by_id
attributes of
the alarm_control_panel
hold those two attributes.
On the ElkM1 panel Global Setting 35, “Transmit Event Log” must be enabled for this to fully work.
Note that without Global Setting 35 set and in a single area system,
changed_by
and changed_by_id
are updated when a user enters a valid
code on a physical keypad.
Global Setting 36 — 40
If you are using the features below then these respective global options should be enabled:
Option # | Option Name | Description |
---|---|---|
36 | Transmit Zone Changes | If you are using Zones this allows Home Assistant to track the status of the Zones. |
37 | Transmit Output Changes | If you are using Outputs this allows Home Assistant to track the status of the Outputs. |
38 | Transmit Automation Task Changes | If you are using ElkM1 Tasks this allows Home Assistant to track the status of the Tasks. |
39 | Transmit Light Changes | If you are using ElkM1 Lights this allows Home Assistant to track the status of the lights. |
40 | Transmit Keypad Changes | Oddly, this option tracks keypad changes and alarm status. If you are wishing to track keypresses on ElkM1 keypad or if you are wishing to track the armed, disarmed, and alarm state of the ElkM1 then this option should be set. |
System Trouble Status
The ElkM1 is able to report general system trouble statuses. This is
reported using the system_trouble_status
attribute of the
panel sensor (often named sensor.elkm1
) in Home Assistant.
The format of the system_trouble_status
attribute is a comma separated list
of the active troubles. Only active trouble statuses are in the list.
If the trouble is for a zone then zone <number>
is appended to the trouble name.
For example, if zone 42 wireless sensor lost communication with the panel then
system_trouble_status
would be “Lost Transmitter zone 42”. If in addition there
was an AC failure then system_trouble_status
would be the string
“AC Fail, Lost Transmitter zone 42”.
The complete list of trouble statuses are:
- AC Fail
- Box Tamper (zone is part of status)
- Fail To Communicate
- EEProm Memory Error
- Low Battery Control
- Transmitter Low Battery (zone is part of status)
- Over Current
- Telephone Fault
- Output 2
- Missing Keypad
- Zone Expander
- Output Expander
- ELKRP Remote Access
- Common Area Not Armed
- Flash Memory Error
- Security Alert (zone is part of status)
- Serial Port Expander
- Lost Transmitter (zone is part of status)
- GE Smoke CleanMe
- Ethernet
- Display Message In Keypad Line 1
- Display Message In Keypad Line 2
- Fire (zone is part of status)
Configuration
To add the Elk-M1 Control integration to your Home Assistant instance, use this My button:
Elk-M1 Control can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.
Manual configuration steps
If it wasn’t discovered automatically, don’t worry! You can set up a manual integration entry:
-
Browse to your Home Assistant instance.
-
In the bottom right corner, select the
Add Integration button. -
From the list, select Elk-M1 Control.
-
Follow the instructions on screen to complete the setup.
Manual configuration
Alternatively, configuration through the configuration.yaml
The configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file
is supported (example below).
Both methods of configuration support “auto configuration”. This works by reporting only elements on the ElkM1 that have a “Name” configured. So, for example, if counter #11 on the panel was configured with the name “Test counter” then this element would show up in Home Assistant. If an element is being used but does not have a name configured then it will not appear in Home Assistant through the auto-configuration feature.
# Example configuration.yaml entry
elkm1:
- host: elk://IP_ADDRESS_1
...
- host: elk://IP_ADDRESS_2
prefix: gh # for guest house controller
Configuration Variables
Connection string to Elk of the form <method>://<address>[:port]
. <method>
is elk
for non-secure connection, elks
for secure TLS 1.0 connection, elksv1_2
for secure TLS 1.2 connection, and serial
for serial port connection. <address>
is IP address or domain or for serial
the serial port that the Elk is connected to. Optional <port>
is the port to connect to on the Elk, defaulting to 2101 for elk
and 2601 for elks
and elksv1_2
. For serial
method, address is the path to the tty /dev/ttyS1 for example and [:baud]
is the baud rate to connect with (Elk systems default to 115200 baud, but this can be changed during Elk system configuration). See ELK-M1XEP section above for information on selecting the appropriate secure version. You may have multiple host sections for connecting multiple controllers.
The prefix to use, if any, for all the devices created for this controller. At most one host can omit the prefix, all others must have a unique prefix within the Home Assistant instance.

Debugging
Debug logs are often required to solve an issue. Follow the instructions on Enabling debug logging.
Sometimes, for example, a problem can occur while starting Home Assistant. In this case, follow these instructions.
Add the following to your configuration.yaml
The configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file in your Home Assistant config
directory:
logger:
logs:
elkm1_lib: debug
homeassistant.components.elkm1: debug
After updating your configuration file, restart Home Assistant. The debug logs will be in the file homeassistant.log
in the config
directory.
