I purchased a Shelly 3EM, which I tought was able to help me analyse the power diagram of the installation with high resolution.
In the past I used a "home made" energy meter with emoncms and I could get readings every few seconds, which automatically generated high resolution graphics.
With Shelly, I can only get the energy graph, and even the export of the data only gives the energy data with 1h resolution (basically it's just the data from the graph, in csv format).
Is it possible to have high resolution power data using Shelly 3EM? Either graphic or csv?
Thanks
