Metering AC power and energy put us to new challenges when compared to DC. Lets first assume a resistive load where current and voltage are always in phase. If we sample with a frequency lower than double line frequency (eg. 100 Hz), we’ll get aliasing noise. For energy metering this noise doesn’t pose a problem ..
Protective Earth Hazard As many cheap inverters from China, it uses a capacitor voltage divider to create a „neutral“ ground. This ground is in fact just centered between the 2 output wires using a capacitive voltage. This poses the problem that current can flow through the ground wire undetected by fuses or other protection components. ..

The SensorPush HT.w is a wireless, battery powered air thermometer and hygrometer. It is pricy, I got it for 90$. Let’s compare it to DIY solution with the DHT22 and an ESP32 for less than 10 bucks. For my application the noise level and accuracy of the DHT22 is s..
