Hi @faelannm ,
We must obviously mention our Ruuvi Station app to begin with, as it is the easiest way to get into world of Ruuvi sensors. We have collected a list of projects to our integrations page to help you find ways to integrate Ruuvi sensors and Ruuvi Gateway to your existing setup.
Grafana is one popular option for visualisation and we have a use case example for using it together with RuuviCollector and InfluxDB here.
I hope this gets you started!
