this message is addressed to all of you who have been running my script as descripted in the homonym tutorial under the dedicated forum folder. According to infos published by the Eclipse Foundation (link: https://bugs.eclipse.org/bugs/show_bug.cgi?id=541419), the team responsible for the Mosquitto server iot.eclipse.org has migrated on late days to a new machine and a new symbolic name. Therefore if you want to keep running the script, you're required to edit the file, find the following line: Code: MQTTHOST="iot.eclipse.org" change it this way, save and reboot: Code: MQTTHOST="mqtt.eclipse.org"
