This is the relay that I used. Everything worked well. I went this route for two reasons, 1, simplicity, 2. it did not have the shelly in series with the existing alarm. I did not want to compromise the existing alarm if the shelly or my wiring failed.

Thanks for the help. I solved my problem a different way. I went ahead a bought an external relay and connected it to the float switch. The output of the relay is connected to the SW input on the Shelly1.

Is there another Shelly product that would allow me to do this? As I mentioned, I do no want to add another device/potential failure mechanism in series.

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?
