Those that have followed my posts will probably know that I have long being looking for a solution to monitor and control at the appliance level. Historically this has been an unsolved challenge; finding something that is network connected, monitors power consumption, provides a web interface and doesn't cost the earth has been impossible. However, last month on another thread someone suggested taking a look at Sonoff PoW.
The module is made in China, where else, but does tick most of the boxes. The final tick box came on discovery that the modules are relatively easy to hack with custom firmware and a very active alternative firmware exists on GitHub. After initial testing last night all appears to work as I had hoped. Integrating into Cortex should be easy because the firmware provides a simple HTML interface (although MQTT would be better).
Details of the module are available on the manufacturers website, note it is CE certified although many people are commenting that current should be kept below 5 Amp due to the tin tracks on the PCB. It is rated at 16 A, 3.5KW.
