Hi,

Quick question, does the shelly work well with HC-SRO4?

Is there a way to connect uni to this device?

HC-SR04

Thanks

Thank you very much - I fully understand now

I didn't research what the Potential-Free means - your drawing helped me a lot!

Thank you!

I have drawn a quick diagram of what i assume should be right?

Does the output (Shelly +) connect to the signal input of the relay?

I assume the relay needs a trigger voltage to NO/NC - ?

Thanks

That's great, thanks for the info -

I am struggling to find the right relay? Are you able to suggest or advise the correct product for this?

I have a 24v Power supply ready to go

I am now looking into this Relay

It requires a signal input, would this be a DC+ signal or DC - ?

Thanks

Hi,

Hoping someone with a bit of electronic knowledge can help?

I am hoping to Connect Uni to a group of water sensors that can actively switch some solenoid valves, However, the solenoids i am looking at require a 24v DC with a current of 1.0A - I assume the voltage is fine but The shelly can only output 0.1a /0.3w

Is there a device that can boost the current?

I am looking at the device below - would this work?
