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?
Something like this https://amzn.eu/d/gG3Oveq will do what you want
Thank you, that is precisely what I ordered last night so that I could try, I'm glad you've confirmed my idea.
I just need to use the relay analogue output to close the circuit and use a receiver to switch on the immersion heater.
I was hoping that Venus would have a built-in wifi way of sending signals to external devices, perhaps in future developments.
