Dear TTN community,
thanks for this story! We want to take the chance to introduce you to Kotori, a full-stack FOSS data historian integrating InfluxDB, Grafana, Mosquitto, MongoDB, dygraphs, mqttwarn and more with each other.
It offers multi-channel, multi-protocol and multi-tenant data acquisition and data export features and is super easy to install and operate.
The system might be interesting to the whole TTN community for different tasks in the field of measurement data collection and storage, data telemetry, environmental monitoring and beyond. As it was designed to glue best-of-breed FOSS components together, it could be a viable alternative to platforms like Thingspeak or Opensensors.io. However - through its open architecture - adapters to other systems are possible and encouraged.
We appreciate comments and suggestions and will be happy to answer any questions.
With kind regards,
the Kotori developers.
