![Doorbell WiFi Upgrade [DIY, IoT, Node-RED, WLED]](https://i.ytimg.com/vi/NP7_cPEDocI/mqdefault.jpg "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 isnt audible but can also be use for hearing disabled people.
Code and Noder-RED flow can be found here:
