esphome_syslog

A simple syslog component for esphome. The component is designed to auto attach itself to the logger core module (like the MQTT component does with the log_topic)

This component uses the https://github.com/arcao/Syslog library version 2.0 at its core

How to

Manually

To install, locate your esphome folder, create a folder named custom_components got into it and execute

git clone https://github.com/TheStaticTurtle/esphome_syslog.git
mv esphome_syslog/components/syslog .
rm -rf esphome_syslog

YAML

external_components:
  - source: github://TheStaticTurtle/esphome_syslog
    components: [syslog]

Configuration

Simply add this to the configuration of your esphome node:

syslog:

When used like this, the component will simply broadcast its log to everyone on the network to change this behavior you can add the ip_address and port option like this:

syslog:
    ip_address: "192.168.1.53"
    port: 514

Default behavior strips the esphome color tags from the log (The 033[0;xxx and the #033[0m) if you do not want this set the strip_colors option to False.

Default behavior also sets enable_logger to True if you wish to disable sending logger messages and only use the syslog.log action you can do so by setting it to False:

The action syslog.log has 3 settings:

then:
    - syslog.log:
        level: 7
        tag: "custom_action"
        payload: "My log message"

Due to the differences in log levels of syslog and esphome I had to translate them, here is a table:

Esphome level	Syslog level
ESPHOME_LOG_LEVEL_NONE	LOG_EMERG
ESPHOME_LOG_LEVEL_ERROR	LOG_ERR
ESPHOME_LOG_LEVEL_WARN	LOG_WARNING
ESPHOME_LOG_LEVEL_INFO	LOG_INFO
ESPHOME_LOG_LEVEL_CONFIG	LOG_NOTICE
ESPHOME_LOG_LEVEL_DEBUG	LOG_DEBUG
ESPHOME_LOG_LEVEL_VERBOSE	LOG_DEBUG
ESPHOME_LOG_LEVEL_VERY_VERBOSE	LOG_DEBUG

This table is however open to discussion as it's my interpretation, if you want to change it you can do so in the syslog_component.cpp file and change the array at line 22

Warning

This component should not break anything and should work with everything however if it doesn't please open an issue. I have successfully tested this component with an esp8266 and an esp32. BUT The esp32 seems to have issue when there is a lot of thing to send very fast which you can see turing boot when it prints the config, see my comment in issue #7 for more details .
