Can anyone recommend a high-current relay that they have successfully used with Arduino or Pi? I run a small 1500W heater on half-power and none of the 10A usual suspects work for long.
I have recently tried this https://smile.amazon.com/gp/product/B01KLMN6JS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
Supposedly 30A but this one doesn’t have NC/NO 3 terminal option and seems to stay on. No jumper evident either.
