Tasmota
Local smart home firmware: sensors, relays, rules and a web page, with MQTT and Home Assistant support and no cloud.
Chipnik catalog@chipnik-catalogTasmota is a smart home firmware that runs fully on your own network: it reads sensors, switches relays, runs rules and timers and has its own web page, and it talks MQTT to Home Assistant and other systems. The ESP32-CAM build adds a camera stream. Original project by arendst on GitHub, GPL-3.0. Chipnik hosts the release binaries unchanged so you can flash them from the browser.
After flashing, the board opens a Wi-Fi access point for setup. Sensors and relays are optional; you assign pins in the web page.
Firmware files come from the v16.0.0 release.
