IotaWattTM is an open-hardware 14 channel WiFi connected AC electric power monitor.

This bundle is tailored for the USA users (see 'includes' section below)

Save 10% over purchasing items individually

It's based on the ESP8266 IoT platform using MCP3208 12 bit ADCs to sample AC voltage and current at high sample rates. Data is saved locally to the on-board SD card and (optionally) posted online to Emoncms.org or another Emoncms server e.g. emonPi. On-board data storage ensures no data-loss in the event of network failure. If network is lost data saved locally will be bulk-uploaded to Emoncms when connectivity is restored.


The IotaWatt is configured via a web-interface, see online demo: iotawatt.com
