esp32-mqtt-telegraf-influxdb

info about programing a esp32 and collecting and storing the information this is a work in progress for my own learning, but also if the information can help others

Software

• Home-assistant (hassos)(rpi4)
• Mosquitto mqtt broker (standalone)
• influxdb v2 (time-series database) (standalone)
• telegraf (agent for translating data from mqtt to influxdb) (standalone)

home assistant discovery

• This mqtt topic structure is to suit home assistant and allow automatic device discovery
• Could not find many other examples on the net that allowed home assistant to find the mqtt devices without requireing having to edit configuration.yaml to add them
• currently have home assistant and influxdb in parallel, both reading seperately from mqtt.
  • homeassitant displaying live data
  • influxdb storing long term sensor data
