Hi I am using Wireless Multichannel wet contact closures https://store.ncd.io/product/long-range-iot-wireless-multi-channel-wet-contact-closure-transmitter/ with 24v DC and detect the input voltage of the device connected with it and send the notification to raspberry pi easily but I also want to check, how much DC voltage every specific device which is connected with contact closure, which is something difficult to know about.
Any suggestions for detecting the voltage specification will be very helpful
 

Hi,

your link points to a device with digital inputs.
If you want to measure voltage, then you should choose a device with analog inputs. (On the same internet page)

hello, thanks for your reply, will definitely look into your advice, but is there any good suggestions to create the push notification for this kind of wireless contact closure which sends email as well as notification smartphones at the same time?
