Docker images for miflora-mqtt-daemon

A simple Linux python script to query arbitrary Mi Flora plant sensor devices and send the data to an MQTT broker.

All credits go to Thom Dietrich for creating miflora-mqtt-daemon.

Image Variants

Miflora2mqtt Docker images come in different variations and are supported by manifest lists (auto-detect architecture). This makes it more easy to deploy in a multi architecture Docker environment. E.g. a Docker Swarm with mix of Raspberry Pi's and amd64 nodes. But also in a non-multi architecture Docker environment, there is no need to explicit add the tag for the architecture to use.

All images are based on Alpine Linux.

Supported architectures are: amd64, arm32v6, arm32v7 and arm64v8.

Usage

docker run -it -e TZ=Europe/Amsterdam --network=host -v <host_path_to_config>:/config --name miflora raymondmm/miflora2mqtt:latest
