This repo contains code and instructions to setup a ESP8266 NodeMCU for monitoring "things" using graphite and grafana.
We use basic ESP8266 client, ping and ntpclient modules to ping google.com at regular intervals and send the results to graphite. We then visualise the data on grafana.
We use a load cell, HX711 load cell amplifier and a ESP8266 NodeMCU for measuring the weight of a "thing". We then use the ESP8266 client to connect to a graphite server and send the weight of the "thing" to graphite. Alerts and visualisation is on grafana.
