Log MQTT to MySQL
Logs all or selected MQTT activity to a MySQL database.
By default logs everything - change the topic in the MQTT node to be more selective (e.g. "my\path\#" or "my\topic")
MySQL table needs the following columns:
- id (integer, autoincrement) (optional)
- timestamp (date-time)
- topic (string 200)
- data (string 200)
Requires node-red-node-mysql and configuration of your MQTT and MySQL server details
