I am very new to HA, my first project I am working on is to make a thermostat using a DS18B20 temperature sensor with a 7" touchscreen for local control with Rpi 3B and two IOPi Plus tophats. I am sensing temp and climate function is working properly. However, I am controlling my boiler with a Stainsmart 16 Channel relay board and these are active low relays. Essentially when HA says to turn off it turns on and vise versa. I have tried invert_logic and negate neither seemed to work. Can anyone point me in the right of what to do?
Please do not suggest using the NC contacts instead
