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.

|
name: "Sim800L RSSI"
|
|
|
|

|
|
|
|

|
|
- **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.

|
|

|
.. _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
|
|

payload: !lambda 'return id(caller_id_text_sensor).state;'
|
|
|
|
|
|

|
|
has been received.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_ussd_received:

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: 0
|
|
|
|
|
|
