Hi to all,
noob question but I’m lousy in coding
I’m building a electric water heater timer/conroller. I want it to heat when one press the button for 30 minutes and then turn off. Button have 3.3V led in it and I want that LED slowly blink. Here is part of my code:
There is no error, but it doesn’t work when I turn on heater from HA. I want to blink when heater is on. Heater will be triggered by button, by timer, by low temperature of boiler and by HA. So, I want to LED be an indicator for heater.
