A lightweight gateway to collect, retain, and forward data from Shelly IoT devices.

Shelly Data Gateway enables efficient data collection from Shelly devices when using MQTT instead of the cloud. It retains data sent spontaneously by devices and organizes it into Cloud Events, which can be forwarded to various sinks (currently, MQTT is supported).

• Collects and retains data from Shelly IoT devices.
• Converts data into Cloud Events format.
• Supports forwarding to MQTT sinks.

The following environment variables are expected:

• LOG_LEVEL Log level for the application. Possible values are debug, info, warning, error, critical, notset. Defaults to info.
• MQTT_HOST Name of the MQTT host

With the configuration stored in a file .env, the tool can be started as follows:

docker run --rm \
  --env-file .env \
  mrtux/shelly-data-gateway:latest

Please replace latest with the version you want to run. The latest version is not guaranteed to be stable.
