Side by side

What it does

Amazon's voice assistant on Echo devices, controlling smart home gear, routines, music and shopping, now upgraded to the generative Alexa+.

Alternative firmware for ESP8266 and ESP32 smart plugs, switches and sensors that gives local control through a web UI, MQTT, HTTP and rules.

Watch out

Voice recordings are processed in Amazon's cloud with no local option, and it pushes shopping and Prime.

Many newer commercial devices are hard to flash, and flashing voids warranties.
