Tool for HomeAssistant MySQL Historical Sensor Data Migration to InfluxDB

Purpose

Migration of the sensor state historical data from MYSQLDB to InfluxDB.

Pre-requisits

Home Assistant: https://www.home-assistant.io

MySQL used as a Home Assistant recorder. I have MySQL 8.

InfluxDB V2 https://docs.influxdata.com/influxdb/v2.0/ I have used official HomeAssistant Guide for the configuration: https://www.home-assistant.io/integrations/influxdb/

Both MySQL and InfluxDB need to be exposed to the host you run the tool on over the network.
