    +-. The geyser is on or off. Size of eliment x hours on.

    That is just for the signal. 3.3 volt, close to zero amp. That is how solid state relays work. It is obviously single pole.

    That is way I use that large heatsink.

    SMART IoT GEYSER

    I builded a Smart Geyser controller using an ESP32 and 50 Amp Solid State Relay. It uses Cayenne IOT Cloud and you can schedule timers and monitor the use of hot water. I am already saving Money. All code and instructions available at https://www.instructables.com/Cayenne-IoT-Geyser/

    Somebody was using hot water from the geyser, but the kettle would have been much more efficient.

    This look like a great Arduino / ESP32 / ESP8266 course. https://www.edx.org/course/a-subjective-introduction-to-the-iot

    Get a good book. Learn python.

    Check peltier eliment and heatsink systems for cooling.

    Unfortunately yes. I hope a proper heatsink will do. For my type of projects low power consumption is important.

    It seems like the ESP32 wifi soil sensor can be repurposed as a rain gauge. Preliminary tests shows that it may be accurate on 0.1 mm. Now I need to see if temperature will effect the capacitive sensor. The gauge will be emptied with a siphon.
