Thankyou so much for your advice and the warning regarding the UNI, it's really appreciated thgoebel and I'll let you know how I go!

Hi Thgoebel, thanks again for sending this through.. it's really appreciated.

Unfortunately, it's difficult for me to translate the diagram given i'm a beginner.

Could I ask you a favour to advise what the A stands for, along with the I and P ? Would you be able to advise what the 500 ohm resistor (R1) looks like, perhaps from the following supplier (who is our only supplier where I live):

Jaycar Electronics | Components, connectors, switches, power, and more

Thank you in advance!

I will also try and do some more research in the meantime.

Hi thgoebel,

Thanks so much for posting this link, I’m not sure why I couldn’t find this before, but I see it now.

I have converted these pages to English and reviewed the diagrams here, but unfortunately as I’m a beginner and as English is my first language, I’m still having trouble trying to follow where you ended up with the overall design and layout.

Essentially I can’t determine if the diagram written half way through the thread is correct and the final design?

I was also having trouble interpreting why two 24v supplies are required? Is a separate one required for the pressure sensor and another for the uni?

An updated diagram with some layman terms would be amazing

Thanks for the reply. I have looked and still can’t find anything.

If you do believe there is something already there, any links would be appreciated!

Hi there, I did have a look before posting, but unfortunately couldn’t find any results that matched my situation.

Any links you can provide would be appreciated!

Hi All,

I have a two-wire pressure sensor (4-20ma) that I'm wanting to read the voltage of with the Shelly Uni, but in order to do so, I need to connect this into a current sensor which will then feed the voltage to the uni.

I have the following items;

Would anyone be kind enough to provide me with a basic wiring diagram and how this can be fed into the uni?

thanks in advance!
