I built a really cool little temperature and air quality sensor that reports data to particle.io events and from there into influxdb cloud. With Free Dashboards!! Yes I mean free as free can get. Particle.io, free (to 100 devices). InfluxDB cloud, free (to (x) amount of stats). We’re not talking about a lot of stats here, but after many hours of research for a free dashboard solution this was the absolute best!
