Please let me know.

Re: Get 24v to switch a 3.3v to read GPIO

I was thinking i could use an NPN. so the base would trigger my GPIO pin.
But now i see that the ground need to be on the same ground as the central heating. (true?)

I think i need to use a relay.
Any suggestions?

Thanks,
Michiel

Re: Get 24v to switch a 3.3v to read GPIO

We will need to know a little more about it to help you: - Are you trying to detect when your heating system is running, or are you trying to tell it when you want it to run? - How does the voltage you are trying to sense vary? Does it switch between 0V an 24V? - Is the voltage AC or DC? Hey Xian. ...

Get 24v to switch a 3.3v to read GPIO

Hey there, I'm quite enthousiastic about the pi en de GPIO options. I have, for me, an awesome idea. But at the moment im stuck. What I need to find out is the following; We use the Honeywell Chronotherm iv as a thermostat for our central heating. What i need to find out is when the honeywell is mak...

Re: Implement network displayer via RPi

Dear Jeffery,

This is exactly what I was looking for.
Is everything working out alright? Is there something we can test for you?

Greetings,
Michiel
