This iRobot system potentially poses a serious hacking risk of your entire smart home devices. My AVG antivirus programs tells me over and over again this serious warning: "MQTT-Misconfigured-Broker". I strongly urge the manufacturer of iRobot to fix this software issue - especially in these critical cyber security times. I will discount our iRobot from our home internet right away - only way to avoid hacker exposure for all our electronic devices. I wrote to the developer but they do not reply!
