Good to know, indeed my setup is working now with stable libraries thanks to this helpful community.
I'll go back later to development libraries to see if I'm able to work with it as well.
@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.
I've added all the files manually so things should be there now (though I'd recommend grabbing things from github to preserve directory structure and get all the files).
