Shelly One for Septic Monitoring

Try connecting the 120V supply to 1 as well. SW controls O, but needs I to be powered as if your going to use O. No danger to your circuit since O not connected through

Hello!

Here is my question, I am trying to use the Shelly 1 not to switch anything, but to alert me when my septic system is in alarm. Attached is my wiring set up. The Shelly 1 is getting power and connecting to the network.

What I am trying to do is tie the Shelly 1 into the existing Alarm system without putting the shelly inline as a potential point of failure of the alarm. I simply want to use the Shelly 1 with some other automation to notify me.

With this setup, I can confirm that the SW port gets no voltage until the float switch is activated. However, when the float switch is closed, it will not trigger the SW and Shelly 1 to function. I can confirm that the 120V supply voltage getting to the switch and then to the SW terminal when the float switch is activated. I have separately tested the Shelly 1 and it is working.

Is there a way to do this without terminating into the SW port?

Sorry, didn’t work. Only way is to put it in the circuit, which you didn’t want. If you put the float switch direct into the I and the O to the lamp it should be fine since dry contacts

At alarm the float switch sends a permanent voltage to the SW terminal and you will see a blue bar on the shelly button displayed in the App or webui. I opened a ticket at Shelly now asking them to use the ‘blue bar’ as an input state in a scene. They closed it; see screenshot.
