Hello. In my project I use a temperature controller https://flows.nodered.org/node/node-red-contrib-heater-controller controller works but ...! I noticed that when you remove the sensor physicaly. controller still works. that is, in the absence of a sensor, it displays the last measured temperature and continues to chase the set temperature. This is not very correct about security, I must emphasize it! I tried to deal with the problem myself, but my knowledge is not that great. I have some achievements but it is not the expected result. I want to send a message inside the function before the controller to stop it. This is a half solution because I send the controller the required temperature of 0 degrees. Please review what I am sending you. Thanks. Greetings. Sorry for bad english.
