Do you use an electric dryer and need a solution to send voice notifications when the cycle is complete? Let's build a simple non-invasive DIY sensor that monitors the electrical draw from the dryer using a Wemos D1/NodeMCU, a couple resistors, capacitor and a split core current transformer. You can also apply this same project to many other electrical monitoring projects in the home.
