I am building a temperature controlled beer fermentation fridge with a raspberry pi 2 and a 2 circuit relay and 1 wire temp sensors. My question is this: if my wifi goes down for some reason, will the relays and temp settings still function? I don’t want to lose a batch of beer to a down wifi connection.
No, triggers will not work without a connection to Cayenne. Schedules, however, are local to the Pi and will work. As far as I know schedules and triggers for Arduino will not work though.
