A demo of using MQTT bindings with Fyne and Go to show weather data of a remote monitoring station.
Connect mqttweather to broker.emqx.io and then send the following command.
mosquitto_pub -h broker.emqx.io -t "homeassistant/sensor/weatherflow2mqtt_ST-42/status/attributes" -m '{"attribution": "Powered by WeatherFlow2MQTT"}'
mosquitto_pub -h broker.emqx.io -t "homeassistant/sensor/weatherflow2mqtt_ST-42/observation/state" -m '{"absolute_humidity": 2.45, "air_density": 1.19, "air_temperature": -7.7, "battery": 2.58, "battery_level": 78, "battery_mode_description": "All sensors enabled and operating at full performance.
