:description: Instructions for setting up the SIM800L GSM module to dial, send and receive SMS in ESPHome.
:image: sim800l.jpg
:keywords: SMS SIM800L GSM
Component/Hub
-------------
The ``SIM800L`` Component provides the ability to dial, answer calls, send/receive SMS text messages and
send/receive USSD codes. The device must be connected via a :doc:`UART bus </components/uart>`
supporting both receiving and transmitting line. The UART bus must be configured at the same speed
of the module which is by default 9600bps. The required connection wires are ``+VCC``, ``GND``,
``RX`` and ``TX``.
.. warning::
If you are using the :doc:`logger` make sure you are not using the same pins for ``TX`` and ``RX`` or
otherwise disable the UART logging with the ``baud_rate: 0`` option.
.. note::
This module requires a power supply between 3.8V and 4.2V that can handle current spikes up
to 2 amps, it will not work by powering from the same 3.3V power source of the ESP. However you can
connect ``TX`` and ``RX`` lines directly without any level shifter.

# Example configuration entry
uart:
baud_rate: 9600
tx_pin: TX
rx_pin: RX
sim800l:
on_sms_received:
- logger.log:
format: "Received '%s' from %s"
args: [ 'message.c_str()', 'sender.c_str()' ]
logger:
baud_rate: 0 # disable uart logger on esp 8266
Configuration variables:
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the UART hub.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- **on_sms_received** (*Optional*, :ref:`Automation <automation>`): An action to be
performed when an SMS is received. See :ref:`sim800l-on_sms_received`.
- **on_incoming_call** (*Optional*, :ref:`Automation <automation>`): An action to be
performed when a call is received. See :ref:`sim800l-on_incoming_call`.
- **on_call_connected** (*Optional*, :ref:`Automation <automation>`): An action to be
performed when a call is connected, either because an outgoing call accepted is
accepted or an incoming call answered.
- **on_call_disconnected** (*Optional*, :ref:`Automation <automation>`): An action to be
performed when a call is disconnected.
Sensor
------
.. code-block:: yaml
sensor:
- platform: sim800l
rssi:
name: "Sim800L RSSI"
Configuration variables:
- **rssi** (*Optional*): The informed Received signal strength indication (RSSI) in dBm.
- **name** (**Required**, string): The name for the rssi sensor.
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
- All other options from :ref:`Sensor <config-sensor>`.
Binary Sensor
-------------
.. code-block:: yaml
binary_sensor:
- platform: sim800l
registered:
name: "Sim800L Registered"
Configuration variables:
- **registered** (*Optional*): Indicates if the SIM800L has successfully registered in the cellular network.
- **name** (**Required**, string): The name for the registered binary sensor.
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
- All other options from :ref:`Binary Sensor <config-binary_sensor>`.
.. _sim800l-on_sms_received:
``on_sms_received`` Trigger
---------------------------
With this configuration option you can write complex automations whenever an SMS message
is received. To use the message content, use a :ref:`lambda <config-lambda>`
template, the message content and the sender phone number are available inside that lambda
under the variables named ``message`` and ``sender`` respectively.
.. code-block:: yaml
on_sms_received:
- lambda: |-
id(sms_sender).publish_state(sender);
id(sms_message).publish_state(message);
.. _sim800l-on_incoming_call:
``on_incoming_call`` Trigger
----------------------------
This automation triggers every time the SIM800L sends a RING / Caller ID message, this message
is sent several times per call, presumably every time the phone "RINGs". The automation provides
a ``caller_id`` string parameter which received information. The phone call is neither accepted
or rejected.
.. code-block:: yaml
on_incoming_call:
- logger.log:
format: "Incoming call from '%s'"
args: ["caller_id.c_str()"]
- lambda: |-
id(caller_id_text_sensor).publish_state(caller_id);
- sim800l.disconnect
- homeassistant.event:
event: esphome.incoming_call_event
data:
payload: !lambda 'return id(caller_id_text_sensor).state;'
``on_ussd_received`` Trigger
----------------------------
With this configuration option you can write complex automations whenever the ussd code from network
has been received.
.. code-block:: yaml
on_ussd_received:
.. _sim800l-send_sms_action:
``sim800l.send_sms`` Action
---------------------------
Send a SMS message to a phone recipient using this action in automations.
.. code-block:: yaml
on_...:
then:
- sim800l.send_sms:
recipient: '+15551234567'
message: Hello there
# Templated:
- sim800l.send_sms:
recipient: !lambda |-
if (id(reed_switch).state) return "+15551234567";
else return "15551234568";
message: !lambda |-
return id(reed_switch).state ? "Door is now OPEN" : "Hey door just CLOSED";
Configuration options:
- **recipient** (**Required**, string, :ref:`templatable <config-templatable>`): The message recipient.
number.
- **message** (**Required**, string, :ref:`templatable <config-templatable>`): The message content.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID of the SIM800L if you have multiple components.
.. _sim800l-dial_action:
``sim800l.dial`` Action
-----------------------
Dial to a phone recipient using this action in automations.
.. code-block:: yaml
on_...:
then:
- sim800l.dial:
recipient: '+15551234567'
Configuration options:
- **recipient** (**Required**, string, :ref:`templatable <config-templatable>`): The number to dial.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID of the SIM800L if you have multiple components.
``sim800l.connect`` Action
--------------------------
Answers an incoming call.
.. code-block:: yaml
on_...:
then:
- sim800l.connect
``sim800l.disconnect`` Action
-----------------------------
Disconnects a call, either dialed in or received.
.. code-block:: yaml
on_...:
then:
- sim800l.disconnect
``sim800l.send_ussd`` Action
----------------------------
Sends a ussd code to the network.
.. code-block:: yaml
on_...:
then:
- sim800l.send_ussd
Getting started with Home Assistant
-----------------------------------
The following code will get you up and running with a configuration updating received messages
on Home Assistant and will also setup a service so you can send messages and dial with your SIM800L.
.. code-block:: yaml
api:
services:
- service: send_sms
variables:
recipient: string
message: string
then:
- sim800l.send_sms:
recipient: !lambda 'return recipient;'
message: !lambda 'return message;'
- service: dial
variables:
recipient: string
then:
- sim800l.dial:
recipient: !lambda 'return recipient;'
- service: connect
then:
- sim800l.connect
- service: disconnect
then:
- sim800l.disconnect
- service: send_ussd
variables:
ussdCode: string
then:
- sim800l.send_ussd:
ussd: !lambda 'return ussdCode;'
text_sensor:
- platform: template
id: sms_sender
name: "Sms Sender"
- platform: template
id: sms_message
name: "Sms Message"
- platform: template
id: caller_id_text_sensor
name: "Caller ID"
- platform: template
id: ussd_message
name: "Ussd Code"
uart:
baud_rate: 9600
tx_pin: TX
rx_pin: RX
sim800l:
on_sms_received:
- lambda: |-
id(sms_sender).publish_state(sender);
id(sms_message).publish_state(message);
on_incoming_call:
- lambda: |-
id(caller_id_text_sensor).publish_state(caller_id);
on_call_connected:
- logger.log:
format: Call connected
on_call_disconnected:
- logger.log:
format: Call disconnected
on_ussd_received:
- lambda: |-
id(ussd_message).publish_state(ussd);
Now your latest received SMS and sender number will be displayed by the text sensors.
To trigger the automation from Home Assistant you can invoke the service with this code:
.. code-block:: yaml
automation:
# ...
action:
- service: esphome.livingroom_send_sms
data:
recipient: "+15551234567"
message: "Hello World!"
- service: esphome.livingroom_dial
data:
recipient: "+15551234567"
Relay management commands received from an authorized sender:
.. code-block:: yaml
sim800l:
on_sms_received:
- lambda: |-
if ( (id(sms_sender).state == "+79991234567") && ( (id(sms_message).state == "relay_1_on") OR (id(sms_message).state == "Relay_1_on") ) ) {
id(relay_1).turn_on();
}
switch:
- platform: gpio
id: relay_1
pin: GPIOXX
