InfluxDB2 custom component for ESPHome

Changes from Jepsson/esphome-influxdb:

• Changed to InfluxDB2 API
• Made usable as external component
• Remove "device" as it can be replaced by a tag
• Made tags by sensor usable
• Added option to switch to https
• field_key can be set manually

Installation

Add this repository as an submodule in your esphome custom_compontents; git clone https://github.com/CalvinSchwartz/esphome-influxdb custom_components/influxdb2

Usage

Add influxdb2 section to your ESPHome configuration file.

Update notes for ESPHome 2024.06

With ESPHome 2024.06 the http component was rewritten. Therefore this component had to be updated. In regards to this component the user has to do nothing. However, as the http component is utilized the corresponding configuration variables for ESP8266 have to be set, see: HTTP Request.

This means setting

http_request:
  verify_ssl: false

for ESP8266.
