Hi all, I just purchased and installed an emonHP, I intend to roll my own domestic hot water diverter valve sensor. What is the logic for the ‘digital’ DHW input, is it logic 1 (3v3) when the valve is powered and moved to the divert (DHW) port and therefore logic 0 (0v) when unpowered and in the CH position? Do I need to configure this input within the emonHP?
Hi @Staedford - yes, it’s 3V3 when it’s powered, 0 V when unpowered. You don’t need to configure anything specific in the emonHP to use this.
