I am not sure when using a dry contact mode what the input voltage needs to be. Is it 120 V, 12 V, 24 V and AC/DC or what?
Also, has anyone successfully connected this to two devices that require a pulse? (Like a garage) and integrated the sensor feedback into s1 and com?
What voltage do s1 and com see in a dry mode.
Thanks
Hello, welcome to the forum.
S1 and Com support only dry contacts of the dead switch (the potential on them is 220 volts). Dry contacts of the relay work according to the settings of the T2 relay regardless of the power supply voltage (24 volts AC, DC or up to 220 volts AC).
In 24 volt power mode for the relay, S1-com DOES NOT WORK.

Thanks for the information. If i connect a sensor to S1 and COM, where can i see the status of the sensor? I can’t seem to find a setting to see it.
Hello, you have the “push” option selected, select “switch”. In push mode, the automation does not show the relay status
Not sure I am following. I want to see the status of the sensor connected to S1 and com. For instance, i have a reed switch attached (like a garage door sensor that tells you if it is open or closed), I just want to see the status of that in the app itself.
Hi, theoretically you want to see whether the physical switch is in the On or Off position, right (the switch is a reed switch)?
You might be better off using a regular reed switch opening sensor. Make an automation - sensor open On switch, sensor closed - switch Off.
I understood the question, you cannot see the state of these contacts (S1 and com). You can only indirectly find out by the state of the relay (provided that you do not switch in the APP), but this will be an unreliable method.
Yeah i have a few other ways to do this, was just hoping that since the relay already has the capability of getting sensor input then why not be able to see it in the app, oh well.
