![]() when the CPU temperature goes over 60 C, an e-mail should be sent to me). With IFTTT I can add alerts on the measurements (e.g. An MQTT subscriber will see to that the measurements are propagated to a cloud service so that I can monitor the values in an external application. My idea is to let the RPi gather board temperature values regularly and then publish these via MQTT. To investigate this further, I want to monitor the CPU temperature without accessing the RPi via ssh or a direct login. The only way to resolve this is to do a hard reboot (then the temperature goes down again). As I can not access the machine, it is hard to investigate the cause of the heat problem (if a process has gone totally wild e.g.). ![]() When the RPi is in this state, it shows a thermometer warning icon and it is not possible to login. Recently I’ve had problems with my Raspberry Pi 3 overheating though I use a heat sink for the processor and have a very modest load on the machine.
