Where to find current voltage?

    As with the older Shelly 1PM, the energy metering of Shelly plus 1PM is done via a BL0937 integrated circuit. This device measures current and voltage and the phase deviation (power factor) between both current and voltage to calculate the electrical power (real power). This value is delivered to the CPU of the Shelly. Unfortunately, the value for real power is transferred only - NOT the actual values of voltage and current! Thus, voltage value (and current) are missing in the WebUI and in the App.

    Amendment: The above statement is true für Shelly 1PM only! With Shelly plus 1PM, real power AND current AND voltage is transferred by the energy metering integrated circuit to the ESP32 (CPU). Hence, voltage and current are available in WebUI and Shelly App. Sorry for the confusion!

    „Nothing in life is to be feared, it is only to be understood.“ (Marie Curie, 1867-1934)

    „Es reicht nicht“, rief Schiller, „Gedankenfreiheit zu fordern, man muß auch denken können, sonst fordert man Gedankenlosigkeitsfreiheit und die ist die Freiheit zur Dummheit, welche wiederum die schlimmste Unfreiheit überhaupt ist!“
