@suhaila96 Hello I have not seen your question since I reviewed this topics, today.
What do you mean about "setup your circuit"? How did you connected you watermark sensor and to what?
@fdlou147 According to my personal experience, I'd recommend to split up Gateway and Node funktionality and use two seperate mcu's.
Wrt. to the code itself: you only set up a debouncer on one of the pins (finally: Pin 5), as you always redefine the same "flags" over and over again. Perhaps have a look at this imo excellent multi relay/button sketch by korttoma here. This one should be not to hard to adopt to your needs (still, I'd recommend two mcu's).
@kimot I am not handling that situation. I'm taking for granted ssr will do his job. Maybe there's some ssr safety topic I'm unaware? Suggestions for a v3.0 are welcome.
About the temperature measuring... I use two sensors. The one in the board protects electronics from temperatures beyond design (60°C). It's near the ssr because the ssr's derating curve is the most limiting condition.
The control sensor is placed in the bottom of the heater. It connects to the board through a 3 pin header connector.
Hi @blackchart,
Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).
