Based on what was wrote I don't think that's the case. He included some special conditions like: >The monitor knows if I take the boat out when I turn on the main boat power and switches the small pump to auto and otherwise stops monitoring. But when the main power is back on, the pump will initially run every half hour and then every hour and then after about a day it will only be running once a day" Though reading closer there are only two relays, and the author talks about controlling both the small pump and the fan with relays, and there is language around the large pump that while isn't conclusive, may indicate it is indeed on a separate float switch and system and the ESP32 is only involved in the monitoring of it. > I have a large pump that only goes off if the small pump fails or the boat is trying to sink. If the float switch lifts, the monitor wakes up and sends an email alerting me.
