Hi I'm getting my toes wet in electric brewing. I only have a 1500 watt element and heating up 18 gallons for my strike water takes about 3 hours. I'm considering getting a smart outlet so I can turn on my element from anywhere using my phone. My question is when I have my control panel built and all switches set up to heat strike water will the PID automatically start to heat to the set point that it was at before the power was disconnected, or do I have to hit a button to turn it on.
