PM1 No Voltage Reading

    I bought two PM1 Plus at the same time and both are marked the same. Both are running 0.9.1 firmware. One shows power and voltage but the other only shows power. The Channel Settings are also different with one having a Maximum Current setting and the other lacking that setting. Did I get different levels of hardware or is there a device setting that is causing the difference?

    RE: 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…
