This ESP32 based WiFi + Ethernet button panel uses MQTT to connect to software. It's designed to work with Home Assistant, but does work with any MQTT devices. It's very much a work in progress project, and I am working on getting the circuit board to a point where I can create these quickly at home and ship them out to people who purchase them. Of course, people can always download the files and make this for themselves. I have a fully working prototype made and I'm proud of myself for learning WiFi and Ethernet programming. I'm working on adding a good web interface and improving functionality. I use it at my church, and I have another church waiting for me to make some more. It's really great for automating lighting scenes and turning systems on and off. I've also created a ProPresenter integration that makes this a super device for churches and event centers. Different slide changes can trigger lighting cues. I'm working on a wall mounted version of the 3D printed case to make this more of a permanent installation. It's powered by USB C, and can be programmed with the internal CP2102n chip or with over the air updates with Ethernet or WiFi via the web interface. Those features are all working in the current version of the firmware. All the files are available on the GitHub page linked at the top. All the buttons on this panel have RGB leds behind them (WS2812b) that illustrate the state of the switch or scene.
