Weather over MQTT

Live data from EMF’s own weather station.

There is a weather station attached to a mast at HQ. Various sensor readings are pushed to MQTT topics listed below every ten seconds.

The broker is at mqtt://mqtt.emf.camp (more info on the MQTT broker page). The prefix for each topic is emf/weather/.
