sorry for my bad english. I need the front and backside from the PCB of my pre-assabled HestiaPi . The Version is V4.0. My Problem is my heater needs a galvanic isolated switch from the relais output. So I had to hack the PCB. I must cut some conducting paths and solder some cables. I will use the cable clamp from the hotwater part and that one for heating and connect it dirctly to he relais switch.
For Information: I dont need the HotWater part.
