esphome
ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems.
If you reflash the Shelly with Tasmota, ESPHome, or WLED, I believe you can explicitly define the PWM frequency, as well as the min/max dimming levels. I use ESPHome with Home Assistant (and explicitly define the PWM frequency), but even if you used Tasmota, you could masquerade it as a Philips Hue or Belkin WeMo device to use with your Echo for now. WLED can connect to Alexa as well.
