Doorbell WiFi Upgrade [DIY, IoT, Node-RED, WLED]

In this video we upgrade a basic doorbell to send notifications over WiFi. With some power harvesting no battery is required. An optional Node-RED server translates the signal and activates a visual notification remotely. This not only helps if the bell isn’t audible but can also be use for hearing disabled people.

Code and Noder-RED flow can be found here:
