This may sound like a silly question but what if I want to switch (on/off) a remotely installed water heater via wifi instead of wiring the Cerbo GX analogue output normally used for relays?
Is there a built-in function or do I have to convert the analog signal to digital?
I'm sure I'm not the first one to have to control an electrical appliance away from the GX without a physical wired connection.
Any comments?
