About This Project
Konnected integrates the wired door, window and motion sensors and sirens of an existing alarm system with SmartThings, Alexa, Home Assistant, OpenHAB and Hubitat. The open-source firmware runs on the ESP8266, built on the NodeMCU Lua firmware, and it powers Konnected's commercial Alarm Panel products; you can also run it on a compatible ESP8266 development board. Devices talk to local platforms through a two-way real-time REST API, or to the optional Konnected Cloud for SmartThings and Alexa. Setup is: flash the firmware and filesystem, join the device's own Wi-Fi network to configure it, then wire the sensors following the getting-started guide. The repository was last updated in 2023, so check the docs for current hardware.
