I’ve created an extended version of the Aeom HEM ST device that works with the HEM v2.
It also includes complete reporting of kWh, Watts, Amps & Volts, and calculated costs - including high and low since kWh reset. Doesn’t need Polling() (sets each metric to report in reasonable frequency), and you can automate resetting by calling the reset() command.
Enjoy, and feedback is welcome
Here’s a screenshot
