@livius Hi,thanks for your reply.My scenario is about the same as yours.The wipy2.0 is a sensornode in the pumstation an monitors a few digital inputs(gpio).in case of an error(digital in changes status) the wipy has to make a connection to the pushover server in the cloud to send the error message. I'm glad to hear that long stable uptimes are possible!

@rolandvs look at watchdog https://docs.pycom.io/chapter/firmwareapi/pycom/machine/WDT.html

@lollisoft Thanks for this information! I'll try this!
